Full textAbstract:
Organochlorine is a type of persistent organic pollutants which can last long in environment due to the resistance towards the microbial degradation. Previously, the organochlorine pesticides are widely used to reduce the pests in the farm so, the crop yield could be increased, and the losses can be decreased. The organochlorine pesticides previously are used without having a proper study on the effect of organochlorine to the environment. Although the use of organochlorine pesticides has been banned, the residues of organochlorine from previous usage, still exist in the environment, causing negative impacts to the environment and human health. The distribution of the organochlorine pollution in Malaysia is required to be studied more to ensure that the organochlorine concentration will not be increasing according to time. Due to the ban of organochlorine pesticides, other pests control methods such as organophosphate pesticides, and integrated pest management are being used by the farmers. However, there are challenges raised such as financial problem of the farmers to afford the new chemicals or methods and the negative effect from the use of new chemicals, and these challenges should be solved to improve the pest control in Malaysia. Impacts of organochlorines on human health and environment are discussed in this review to show the hazard of organochlorines.

ABSTRACTThe green mussel, Perna viridis can be used to determine bioaccumulation levels of organochlorine pesticides in a marine environment. Measurements on pesticide organochlorine concentration in green mussels (Perna viridis) were conducted in March and May 2013. The purpose of this research was to determine the bioaccumulation level of organochlorine pesticides in green mussels which were cultivated in Jakarta Bay. The samples were collected in Jakarta Bay in March and May 2013. The organochlorine pesticides concentration were measured by gas chromatography HP 5890 series II. The results showed that the average concentration of organochlorine pesticides in the small size of green mussells was 12.842 ppb, in the medium size was 27.065 ppb, and in the big size was 108.646 ppb. These concentrations were still lower than safety threshold limit value for seafood stated by EPA (Environment Protection Agency) i.e., 1,500 ppb. The comparation between organochlorine pesticide concentration in seawater and organochlorine pesticide in green mussels (bioaccumulation factor) were 2,140 for small green mussel, 4,510 for medium green mussel, and 18,107 for big green mussels, respectively.Keywords: bioaccumulation, green musselss, organochlorine pesticide, Jakarta Bay

Abstract A survey was conducted from 1993 through 1995 to monitor organochlorine pesticides and their metabolite residues in milk available in local Hong Kong markets. Of 252 samples analyzed, including pasteurized milk, fresh milk, and raw milk, 42 contained organochloride pesticide residues at levels exceeding the Extraneous Maximum Residue Limits of the Codex Committee on Pesticide Residues. DDE and HCH isomer levels were substantially higher than those found in a 1984–1987 survey, probably because the source of cow’s milk has shifted from local dairy industries to mainland China over the past decade. Although organochlorine pesticides such as DDT and HCH have been banned in China since 1983, residues of such compounds may still persist in the environment and cause contamination through the food chain.

This paper collected 18 soil samples in the Chin-sha River basin, and analyzed residues of organochlorine pesticides (OCPs) in soil using gas chromatographic method, revealing the organochlorine pesticide residues, the distribution and sources in the river basin. The results show that, the relatively high sampling residues of organochlorine pesticide distribute in the industrial area. The composition and characteristics of organic chlorine pesticide show that the organochlorine pesticide residues in soil mainly come from the historical use. Compared with the domestic similar research, residual organochlorine pesticides in Chin-sha River basin were lower.

Organochlorine pesticides derived from the chlorination of cyclic and/or aromatic hydrocarbons. But, due to their persistence in the environment and their bioaccumulation in the body leading health problems, they were banned from using.They have been widely used around the world in agriculture and public health in particular in Cote dIvoire. This study was aimed to determine the concentrations of organochlorine pesticides residues in soils and crops from Hambol region (Cote dIvoire) and to evaluate the potential carcinogenic risk based on the concentrations found.Organochlorine pesticides residues were determined in soils and crops in cotton fields by using an HPLC. Soil samples analysed showed the presence of five organochlorine pesticide residues namely DDT (ND - 0.39 µg/kg), lindane (ND - 0.972 µg/kg), α-endosulfan (ND - 0.481 µg/kg), β-endosulfan (ND - 0.435 µg/kg) and sulfate-endosulfan (ND - 0.44 µg/kg). In crop samples, no pesticides were detected. The concentrations of detected organochlorines in soil samples were less than United States and FAO maximum residues limits for agricultural soils. The cancer risk assessment and hazard quotient values are under 10-6 and 1. The risks related to farmer exposure to DDT and lindane from soil via ingestion, inhalation and dermal route is negligible.

Abstract I compared pesticide levels in the eggs of Loggerhead Shrikes (Lanius ludovicianus) collected from Illinois in 1995–1996 with those reported for the state in 1971–1972. Pesticides were detected in 19 of 21 (90%) eggs from 1995–1996. DDE was the most frequently detected pesticide, occurring in 17 of 21 eggs. DDT was the second most frequent pesticide detected and was found in nine eggs. Mean DDE levels in shrike eggs from 1995–1996 were 79% lower than in eggs from 1971–1972. Unlike most bird species for which pesticide levels are known to have been reduced (whose populations have tended to increase), Loggerhead Shrike populations have declined during the period in which pesticide levels within their eggs has been reduced. These data suggest that organochlorine pesticides are likely not driving current Loggerhead Shrike declines in Illinois. Los Pesticidas Organoclorados no Están Implicados en la Disminución de Lanius ludovicianus Resumen. Comparé los niveles de pesticidas en huevos de Lanius ludovicianus colectados en Illinois entre 1995 y 1996 con los niveles de pesticidas reportados para el estado entre 1971 y 1972. Se detectaron pesticidas en 19 de 21 huevos (90%) entre 1995 y 1996. El pesticida detectado con mayor frecuencia fue DDE, el cual se detectó en 17 de 21 huevos. DDT fue el insecticida detectado con la segundo mayor frecuencia, y fue encontrado en nueve huevos. Los niveles medios de DDE encontrados en los huevos de 1994– 1996 fueron un 79% más bajos que en huevos de 1971–1972. A diferencia de la mayoría de las especies de aves para las cuales se sabe que los niveles de pesticidas se han reducido (cuyas poblaciones han tendido a aumentar), las poblaciones de L. ludovicianus han disminuido durante el período en que los niveles de pesticidas hallados dentro de sus huevos han sido reducidos. Estos datos sugieren que probablemente los pesticidas organoclorados no están causando la disminución actual de las poblaciones de L. ludovicianus.

Abstract The levels of contamination with various organochlorine pesticides (such as total HCH, heptachlor, heptachlor epoxide, aldrin, dieldrin, endrin, endosulfan, and total DDT) of different foods from 3 traditional markets were determined to estimate Taiwanese daily intake of organochlorine pesticides. Of the 18 organochlorine pesticides investigated, α-HCH, β-HCH, lindane, δ-HCH, heptachlor, heptachlor epoxide, dieldrin, endrin, α-endosulfan, p,p′-DDE, and p,p′-DDT were detected at concentrations ranging from 0.26 to 10.2 ng/g wet weight. Contamination with organochlorine pesticides followed the order heptachlor > dieldrin > α-endosulfan > HCH isomers > heptachlor epoxide > DDT. Frequencies of detection of organochlorine pesticide residues ranged from 2.0 to 52.3%. α-Endosulfan was the most frequently detected organochlorine pesticide in the foods analyzed, followed by heptachlor epoxide (47.6%) and α-HCH (38.9%). Estimated daily intakes (EDIs) of organochlorine pesticides from foods were 1.137 μg for total HCH, 2.147 μg for heptachlor, 0.702 μg for heptachlor epoxide, 0.624 μg for endosulfan, 0.098 μg for cyclodiene, and 0.541 μg for total DDT. These EDIs were only 0.075% of the acceptable daily intake (ADI) for lindane, 47.5% of ADI for heptachlor and heptachlor epoxide, 0.045% of ADI for total DDT, and 1.01% of ADI for aldrin and dieldrin. Therefore, consumption of the foods analyzed does not pose a risk to consumer health.

Full textAbstract:
Many human diseases such as cancer, neurological diseases, autism and diabetes are associated with exposure to pesticides, especially organochlorine pesticides. However, pesticide exposure is also associated with cardiovascular disease (CVD) as the leading cause of death worldwide. In this systematic review, results on the link between organochlorine pesticide pollution and CVD were collected from databases (Medline (PubMed), Scopus and Science Direct) in May 2022 from studies published between 2010 and 2022. A total of 24 articles were selected for this systematic review. Sixteen articles were extracted by reviewers using a standardized form that included cross-sectional, cohort, and ecological studies that reported exposure to organochlorine pesticides in association with increased CVD risk. In addition, eight articles covering molecular mechanisms organochlorine pesticides and polychlorinated biphenyls (PCBs) on cardiovascular effects were retrieved for detailed evaluation. Based on the findings of the study, it seems elevated circulating levels of organochlorine pesticides and PCBs increase the risk of coronary heart disease, especially in early life exposure to these pesticides and especially in men. Changes in the regulatory function of peroxisome proliferator-activated γ receptor (PPARγ), reduction of paroxonase activity (PON1), epigenetic changes of histone through induction of reactive oxygen species, vascular endothelial inflammation with miR-expression 126 and miR-31, increased collagen synthesis enzymes in the extracellular matrix and left ventricular hypertrophy (LVH) and fibrosis are mechanisms by which PCBs increase the risk of CVD. According to this systematic review, organochlorine pesticide exposure is associated with increased risk of CVD and CVD mortality through the atherogenic and inflammatory molecular mechanism involving fatty acid and glucose metabolism.

Full textAbstract:
This study reports the presence, distribution pattern, concentration levels and health risk assessment of organochlorine pesticide residues in fresh and cured fish species in South-South Nigeria. The concentrations of organochlorine pesticides in fresh and cured fish were analysed with Gas Chromatography/ Mass Spectrophotometry (GC-MS) after Soxhlet extraction of the fish species. The study revealed that no organochlorine pesticide was present in fresh fish. However, cured fish species from all the markets sampled had at least two organochlorine pesticide residues which ranged from endosulfan (0.252±0.0022–748±0.004ug/g), lindane (0.386±0.010–0.443±0.009 ug/g), heptachlor-epoxide (0.328±0.005–3.162±0.010ug/g), ortho-para-dichloro-diphenyl-trichloro-ethane (o,p’-DDT) (0.021±0.001–0.180±0.030ug/g) and aldrin (0.140±0.040–2.770±0.020ug/g). These levels are far higher than the maximum residual limit and allowable daily intake values recommended by World Health Organization (WHO) and Food and Agricultural Organization (FAO). There were no pesticide residues in fresh fish probably because the fisher folks in the study area may have abolished the use of obnoxious fishing methods due to the awareness of threats to the aquatic ecosystem. The high percentage occurrences, amounts and distribution of organochlorine pesticides in cured-fish from markets sampled could be as a result of the fact that these organochlorine pesticides were consistently used in the study area by fish processors, distributors and sellers. Human risk assessment of this study revealed a potential danger in the consumption of cured-fish containing the organochlorine pesticides seen in the study.

Most of the locally consumed beans in our vicinity contain excess chemicals of pesticides residues which are harmful to humans and environmental hazards to ecosystem. Investigation of this study revealed contamination level of organochlorine pesticides residues in dried beans originating from Nigeria with a view to controlling them, it also studies crude fiber of beans showed that B4 has the highest fiber content, 27.85% and the order of decreasing value as B4, B5 , B1, B3 and B2. The least percentage of crude fiber was shown by B2 in all the beans samples analyzed. This study also investigated the pesticides residue components of the organochlorinated pesticides test. The presence of pesticide residues in all 14 types of organochlorine pesticides in beans is lower than a previously reported level. Despite this, the amount of organochlorine pesticides tested is more than the permitted levels of 0.01 to 0.2 mg/kg, indicating that the beans consumed in the Gombe metropolis included pesticide residues beyond the permissible limit.

This study uses repeated measures to document the pesticide exposure of rural and urban Latinx children (age eight at baseline), and to compare these children in terms of the frequency and concentration of their exposure to a large set of pesticides, accounting for season. We used silicone wristbands worn for one week up to ten times at quarterly intervals from 2018 to 2022 to assess pesticide exposure in children from rural farmworker (n = 75) and urban non-farmworker (n = 61) families. We determined the detection and concentrations (ng/g) of 72 pesticides and pesticide degradation products in the wristbands using gas chromatography electron capture detection and gas chromatography mass spectrometry. The most frequently detected pesticide classes were organochlorines, pyrethroids, and organophosphates. Controlling for season, organochlorine or phenylpyrazole detections were less likely for rural children than for urban children. Detections of organochlorines, pyrethroids, or organophosphates were lower in spring and summer versus winter. Controlling for season, urban children had greater concentrations of organochlorines, while rural children had greater concentrations of pyrethroids and Chlorpyrifos. Pesticide concentrations were lower in winter and spring compared with summer and fall. These results further document that pesticides are ubiquitous in the living environment for children in vulnerable, immigrant communities.

Abstract Organophosphorus, dithiocarbamates, and some synthetic pyrethroids pesticides, which are commonly used in Egypt for pest control, were monitored, as well as persistent organochlorines, which had been prohibited from use several years ago. Fruit and vegetable samples (397) were collected from 8 local markets and examined for 52 pesticides. Of all analyzed samples, 42.8% contained detectable residues, of which 1.76% exceeded their maximum residue limits (MRLs). The rates of contamination with the different pesticides were 0-86%. However, violation rates among contaminated products were very low, ranging from 0 to 4.6%. In general, organochlorine pesticide residues were not detected in most samples. Dithiocarbamate residues were found in 70.4% of 98 samples analyzed for dithiocarbamates, but only one grape sample had residues exceeding the MRL established by the Codex Committee on Pesticide Residues.

The use of pesticides in the agricultural sector can overcome pest attacks and diseases on crops. Pesticide residue levels that exceed the maximum residue limit (BMR) will be a bad effect on health and the environment. Pesticides that cause the most damage to the environment and human health are the organochlorine group. Levels of organochlorine pesticide residues can be analyzed through gas chromatography (GC) methods. This study aims to describe the levels of organolcorin pesticide residues in a wide variety of plants using gas chromatography (GC) methods. The results of analysis from several literature studies show that the use of gas chromatography (GC) methods can analyze organochlorine pesticide residues contained in plants because they have a high level of sensitivity.

The concentrations of organochlorine pesticide residues were analysed in some vegetables and fruit (spinach, lettuce, cabbage, tomatoes, carrots and onions) grown at Dagachi farming areas along River Galma of Zaria in Kaduna State, Nigeria. Sample collection and preparation were carried out using standard procedures. The concentrations of all the pesticides in the fruits and vegetables samples were analysed using quick easy cheap effective rugged and safe (QuEChERS) multi- residue extraction and clean up techniques, followed by gas chromatography – mass spectrometry (GC – MS). The most commonly detected organochlorine pesticide residues in the entire samples analysed are lindane, delta – BHC, heptachlor epoxide (B), endosulfan I, dieldrin, and endosulfan II. Furthermore, the results of the study shows that the mean concentration of these organochlorines pesticide detected were higher in onion and spinach with heptachlor epoxide (B) having concentrations 2.303 mg/kg and 2.011 mg/kg respectively. Likewise, endosulfan II (1.433 mg/kg) in lettuce was observed. Heptachlor epoxide (B) detected were also very high in other samples such as carrot, cabbage, and tomatoes and with values 0.600 mg/kg, 0.716 mg/kg, and 0.524 mg/kg respectively. Indeed, these concentrations of all the organochlorine pesticides detected in the fruit and vegetables samples analysed were observed to be at alarming levels, much higher than the maximum residue limits (MRLs) by the Codex 2009 (WHO and FAO) except for lindane with values 0.007 mg/kg and 0.01 mg/kg in carrot and onions respectively

Residual levels of organochlorine and organophosphorus pesticides in surface water in some agricultural areas at Ho Chi Minh City were investigated in 2012. Four organophosphorus pesticides including Malathion, Parathion, Ethion and Trithion and seven organochlorine pesticides including Alpha - HCH, beta-HCH, gammaHCH, aldrin, Heptachlor – epoxide, AlphaEndosulfan and Endosulfan-sulfate were determined in the surface water in four dicstricts : Binh Chanh, Hoc Mon, Cu Chi and Binh Tan using gas chromatographic method with electron capture detector (GCECD). The results showed that residues of pesticide were found with high concentrations in surface water in agricultural areas and pesticide residues changed depending on growth stages of crops. The concentration and distribution of pesticides were different in the water samples at different sites. Residues of pesticides such as Parathion, Ethion and Trithion were detected in surface water although these chemicals had been banned.

Pesticides are toxic chemicals used mainly in agriculture to control pests and increase production. The use of pesticides is increasing with the development of special agricultural areas in the Nagari Sungai Nanam Solok district. Organochlorine pesticides are still used to control diseases on agricultural land, while the use of organochlorine pesticides has been prohibited due to the persistent effects they produce. The research aims to look at the potential environmental impacts caused by the use of specialized organochlorines on public water resources that are vital to daily life. The study used random purposive sampling techniques to determine respondents' characteristics and the water sources used. This study's respondents comprised 85 people obtained from the village group in the Nagari Sungai Nanam district of Solok. In contrast, the water samples were obtained from Galian wells and Pamsimas facilities. The results of the study showed that the level of risk of 8 (eight) means used by society could be determined by using the IKL form: there are two means (25%) at the high-risk level, three means (37.5%) at the medium-risk level, and three means (37.5%) at the low-risk level. As a result of the water sample testing, eight sampling sites found a concentration of lindane that exceeded the threshold of 0.45 ug/L lindane in the sample L.2771 (a water well in Jorong Pasa) and 0.62 ug/LL in the L.2775 sample (well water in Jorong Taratak Pauh). This condition describes the potential for higher pollution of wells due to organochlorine-like pesticides or other types that can harm health and the environment. The high use of pesticides, if not limited, will be a danger in the future for the surrounding community, which can lead to death, so an in-depth study is needed regarding the effect of pesticide use on the health conditions of the community and its environment.

The results showed high rates of pesticide residues contamination in the tested precooked fonio samples into twenty nine of 36 samples (75%). About 59% of the samples have contained two or more pesticides while 30% three or more pesticides. The Endosulfan β was the most detected pesticides (15 times) in our samples followed by the pp’ DDT (13 times). The total pesticides residues per samples of the five pesticides active ingredients have varied from 0.037 to 1.874 mg/kg. In other side, the total residues per individual pesticide varied from 3.377 mg/kg for op’ DDT to 0.984 mg/kg for Dieldrin. According to the Codex Alimentarius norms, the most of the tested precooked fonio are unsafety for consumption. These data showed that these organochlorine pesticides are present in our foodstuffs despite their prohibition.

Cereal grains such rice, sorghum, maize and millet among others are the staple foods in large parts of the world, supplying most of the energy and bulk in diets. Pesticide residue analysis in cereals from the various sampling locations for this dissertation revealed the following organochlorines Aldrin, Dichloran, Dieldrin, Endrin, Endosulfan, Mirex, Lindane, Methoxychlor, Heptachlor Epoxide, 1,1,1-Trichloroethane, Hexachlorocyclohexane, and 2,2-bis(p-chlorophenyl). The presence of pesticide (Organochlorines) residues is detected in the samples of cereals (Rice, Maize, Millet and sorghum) analyzed. This could be as a result of high utilization of various pesticides during plant, cultivation and storage thus leading to the bioaccumulation of this substance in the individual cereals. It indicates high levels of non-carcinogenic risk associated with the life time consumption of cereals produce and sold within this region. Organochlorine pesticides also detected suggest the continuous use of obsolete banned pesticides in the cultivation and storage of cereals. Based on findings from this study’s, I hereby make the following recommendations. Regulatory agencies in Nigeria should step up efforts to ensure compliance with the ban on these chemicals. Farmers and other pesticide users also need to be educated on the dangers of using banned products and on the over application of these pesticides. Furthermore, farmers should be educated on the properly usage of these chemical product, during plant, harvest and storage. Also, manufacturers of these chemicals should produce less toxic pesticide using organic materials in other to prevent the health risk associated with chemical pesticide and their residues in food crops and the environment.

Abstract A supercritical fluid extraction and cleanup procedure was developed for separating organochlorine and organophosphorus pesticides from fats. Supercritical carbon dioxide modified with 3% (v/v) acetonitrile was used to extract the pesticides at 6O°C and separate the pesticides from the fats at 4000 psi and 95°C on an in-line C? silica-based column. The extraction and cleanup procedure gave good recoveries for 43 of 62 nonpolar to moderately polar organochlorine and organophosphorus pesticides from fats, whereas 49 were recovered through conventional Florisil column cleanup before quantitation. This procedure can extract and clean up pesticide residues from 0.65 g animalbased fat and 1.0 g oils. Coeluted residues in the pesticide fraction ranged from 2.5 mg for butterfat to 0.8 mg for corn oil. Results for samples analyzed with this integrated extraction cleanup procedure were reproducible and comparable with results obtained with the current Total Diet Study methodology.

In response to reported increased cancer risks among farmers, the Agricultural Health Study (AHS) was designed to examine health outcomes and environmental exposures among farm families in the United States. In the pilot phase of the AHS, food, beverage, air, dermal, dust, surface wipe, and biological specimens (blood and urine) were collected and analyzed for six farm families in two states (IA and NC). In addition, questionnaires were administered to examine previous pesticide use. This paper reports the organochlorine pesticide results of the serum and dietary analyses as well as questionnaire results from the pilot exposure study of farmers and their families. Note, no organochlorine pesticides were reported as currently being applied to the study farms. In all human serum samples examined, typical U.S. population levels were found for the majority of the pesticides. In addition, human serum levels of organochlorine pesticides showed no significant daily or seasonal variation. However, serum trans-nonachlor levels were found to be higher in people living on the two farms in North Carolina than

Pesticides used in agricultural fields pose harmful effect to non-target organisms such as humans and many other aquatic and terrestrial organisms either directly or indirectly especially when they find their way into water bodies. This study is aimed at conducting a risk assessment of pesticide residues in water samples from River Gongola, Adamawa State, Nigeria. Samples were collected randomly from different points along the river. Water samples were collected by lowering pre-cleaned plastic bottles into the bottom of the water body, 30cm deep, and allowed to over flow before withdrawing. Sampling points were approximately 50m away from each other. Pesticide residues in the collected samples were determined using GC/MS analysis with helium gas as a carrier. The levels of pesticides detected were compared with the maximum residue levels (MRL), the estimated daily intake (EDI) and health risk index (HRI) of each pesticide residue. Results of the analysis revealed nineteen (19) different pesticide residues belonging to organochlorines, organophosphates and pyrethroid class of pesticides. The concentrations of the pesticide residues detected in the water samples occurred below the maximum residue levels but above the acceptable daily intake set by European Union. The health risk index of each pesticide residue detected was below 1. Hence, life time consumption of water containing these pesticides poses no significant health threat. However, the presence of banned organochlorine pesticide residues is a cause for alarm.

Abstract Suspended sediment and extracts of the aqueous phase were collected in 1981 at eleven locations in the Lower Great Lakes Region and analyzed for 17 organochlorine pesticide residues and PCB's. Mirex, and p,p'-DDE when found were predominantly in the suspended sediment fraction, whereas α-BHC, γ-BHC, dieldrin, endrin, p,p'-TDE and trans-chlordane were most abundant in the aqueous phase. Several pesticide residues, notably cis-chlordane, p,p'-DDT and p,p'-methoxychlor were found to have variable distribution characteristics between the suspended sediment and aqueous phases. The greater proportion of organochlorine pesticides present in Lake Erie and the Niagara River were found in the aqueous phase samples, which contained at least 90% of the total pesticide concentration at 5 of the 6 stations sampled. Virtually all of the organochlorine contaminants present in Lake Ontario were found in the aqueous phase, which contained 100% of the pesticides and 91% of total PCB's. Similar results were obtained for the St Lawrence River.

Organochlorin and organophosphorus pesticides are broadly applied in agriculture, primarily to boost crop yields and protect crops from pests to reach the needs of a growing global population. This review aims to assess levels of pesticide residues in grains, fruits, and vegetables from already established secondary data from different authors or journals. The data obtained adequately confirmed the presence of concentrations of Organochlorin and organophosphorus residues in vegetables, grains and fruits. Both high and low concentration levels of pesticide residue were documented based on data obtained which showed application of the synthetic pesticides by farmers. The high or minute concentration of synthetic pesticides poses adverse health effect on human. This review suggest that consumers of these type of pesticides contaminated food are liable to contact diseases associated with pesticides. Pesticides have been related to damage to the kidneys, liver, and nervous system, birth defects, cancer, immunodeficiency, reproductive process disruption, and altering or interfering with normal endocrine system function. Thereby, the use of natural pesticides as an alternative to synthetic pesticides for pest control is highly recommended for food security and sustainable environmental practices.

Fruits have nutritional value, but they can also be sources of toxic contaminants, such as pesticide residues. Pesticides used for fruit production results in increased health risks and health costs, humiliation of the environment and productivity loss. This research aimed to conduct to estimate presence of pesticide residues in summer season fruit purchase from local market. Pesticides were precisely detected in fruit samples collected from the market and the technique (GC-ECD) was used for analyzing and studying organochlorine pesticides in three fruits of the summer season, i.e., (plum, kiwi fruit and pineapple). The maximum residual limits (MRLs) values were compared with pesticide concentrations. In fruit sample, mean values of pesticide concentration residues were found. All fruits were found to be contaminated with pesticides. The concentrations of monitoring pesticides were less than the (MRL) values. However, the severe health problems may be created by the regular eating of pesticide infected fruits. It can be concluded that the periodical monitoring of fruits for pesticide residues is essential to evaluating their contamination grade and producing awareness on the health hazards involved in pesticide misuse.

Full textAbstract:
Abstract Fillets from 11 species of commercial fish from the Great Lakes were analyzed for residues of 39 polychlorinated biphenyl (PCB) congeners and 24 other organochlorine compounds. Eel and trout contained the highest amount of PCB (753 and 633 ppb wet weight, respectively) and other organochlorines (607 and 1404 ppb, respectively); perch and carp contained the lowest residues. The pentaand hexachlorinated PCBs were the major congeners in all species except whitefish, in which the tetrachlorinated congeners predominated. Toxaphene was the most abundant organochlorine pesticide in trout; p,p′ -DDE was the major component of this class in eel. Residue concentrations in commercial carp were compared with residues present in carp from a fishery closed to commercial operation. Although both PCB and organochlorine pesticide levels in carp were among the lowest for all commercial fish samples, levels from the contaminated area were among the highest.

Abstract Silicone wristbands have been used to measure exposure to pesticides and other chemicals among children and younger farm workers, but not in older adults. Thus, we aimed to examine exposure to pesticides using silicone wristbands in a small cohort of older adults living on agricultural land, with variable contact with fields and pesticides. We also investigated correlations between pesticide levels on wristbands and urinary pesticide metabolites. Organophosphate (OPH) pesticides and several organochlorines were measured in wristbands worn by 15 males age 70+ (10 farmers using pesticides and 5 non-farmers with no recent pesticide use). Wristbands were worn continuously for 5-days. End-of-day urine samples were collected on days 1-3-5. Spearman correlations and Wilcoxon Scores were calculated. Five pesticides were quantified in the wristbands and detection frequencies ranged from 40-90%. In urine,12 OPH metabolites were quantified, but only 5 were detected in >50% of the samples. None of 5 urinary herbicides were detected. Imputation was performed by dividing minimum-detect by square-root-2. Malathion was only detected in farmers compared to non-farmers. Correlations between OPH urinary metabolites and wristband were examined but only two were significant and were negative in direction. Notably, organochlorine DDE on the wristbands was significantly correlated with 3 OPH metabolites. These unexpected relationships, based on small numbers, suggest a need to replicate this work in a larger study sample to explore potential for confounding or mixtures in future studies of pesticides and health in older farmers.

Breast cancer (BC) is becoming one of the most prevalent non-infectious disease in low and middle income countries. The steady rise of BC incidence may be related to the different risk factors. Among many, rampant presence of environmental pollutants might be one of the risk factors. Therefore, the aim of this study is to investigate exposure to organochlorine pesticides as a risk factor to breast cancer. A case-control study design was employed among breast cancer patients and non-breast cancer individuals (controls). Blood samples were collected from 100 study participants (50 cases and 50 controls) followed by serum separation, extraction and cleanup using standard analytical procdures. The findings revealed that ten organochlorine pesticides were detected in the serum of the study participants. From the detected organochlorine pesticides, heptachlor was observed at higher concentration for breast cancer patients (6.90±4.37 μg/L) and controls (9.15±3.84 μg/L). Mean serum level of p,p’-DDE, p,p’-DDT, heptachlor, gamma-chlordane, endosulfan, and dibutyl-chlorendate were significantly higher in the serum of breast cancer patients than the controls. From the studied pesticides, p,p’-DDT and gamma-chlordane are significant predictors for BC, while, others are equivocal. A unit increment of the concentration of p,p’-DDT (AOR; 2.03, 95% CI: 1.041–3.969) increased the odds of developing breast cancer by two, while for gamma-chlordane (AOR;3.12, 95% CI; 1.186–8.203) by three. Our study results suggesting that, organochlorines are a risk factors for breast cancer in Ethiopia. Decreasing exposure to such organochlorines might have a significant public health relevance in reducing non-communicable chronic illnesses. Besides, continues monitoring of persistent organic pollutants using body biomarkers is important for disease prevention and device mitigation measures.

Agricultural activities cannot be separated from the use of agrochemical, both chemical fertilizer and pesticides. As the largest water user sector, agricultural activities are a source of water pollution. This study was carried out in Brantas’ upper stream along paddy fields, Karangploso Subdistrict, Malang District. The river water samples were collected along the paddy field. The samples were collected when ahead of the harvest season. During the harvest season, pesticides were not sprayed but the concentration of pesticides in the river is quite high. Because no studies have previously measured Organochlorine Pesticide levels in the river along paddy fields, this study is an important contribution to the knowledge of organochlorine contaminants present in surface water in Karang Ploso Subdistrict. The river water has a high concentration of organochlorine pesticides of 400.000 ppt, Total Dissolved Solids (TDS) of 226,8 mg/L, Biological Oxygen Demand (BOD) of 10,2 mg/L, Dissolved Oxygen (DO) of 3,8 mg/L, Chemical Oxygen Demand (COD) of 36,4 mg/L, total phosphate (PO4-) of 0,2 mg/L, nitrate (NO3-N) of 0,7 mg/L, Total Suspended Solids (TSS) of 53 mg/L, and potential of Hydrogen (pH) in lab and field of 8 and 7,08, respectively.

Obsolete organochlorine pesticides are currently prohibited as persistent organic pollutants. If undisposed they continue to pollute soil and water, to accumulate in the food chain and to harm plants, animals and human body. The aim of the study was to assess the pollution of water and soil around the warehouses by unutilized banned organochlorine pesticides and their possible genotoxic effects. Former warehouses of pesticides were investigated in two settlements of Zhambyl district of Almaty region. Chemical analysis showed contamination of the soil around the warehouses with organochlorine pesticides and heavy metals. Water and soil samples taken near the storage facilities were used for environmental risk assessment. The genotoxic effect of water and soil samples was evaluated on various model objects: Salmonella typhymurium, Drosophila melanogaster, Allium cepa, sheep and human lymphocyte cultures. It was found that water and soil samples caused a weak mutagenic effect in all model systems, increasing the frequency of mutations and chromosomal aberrations. Although a genotoxic effect was demonstrated for each of models, different models showed different sensitivity to the action of pesticides and varied degrees of response. Therefore, for adequate assessment of the mutagenicity of pesticides, it is necessary to use a battery of tests with different model objects. The results demonstrated that obsolete pesticide residues still pollute the environment and must be disposed of in a safe way in a timely manner to avoid environmental pollution.

The new data on the organochlorine pesticides pollution of the bottom sediments of Nakhodka bay and Partizanskaya river were obtained in 2020–2021. The objective of the article is to report the organochlorine pesticides pollution level of the bottom sediments and to define the possible sources of organochlorine pesticides in the marine environment. Techniques: sample collection of bottom sediments, Gas Chromatography Mass Spectrometry analysis of samples, Gas-liquid Chromatography method with electronic capture detector, statistical processing, assessment of the organochlorine pesticides contamination of sediments. Results. The new data were obtained on the organochlorine pesticides concentrations in Nakhodka bay in 2020–2021. The previous data on the studied area are described. The concentration of HCH pesticides (α- , β- and γ-HCH), DDT and its metabolites was analyzed. It was found that the concentration of α- , β- HCCH and DDT in bottom sediments increased in 2021.To determine the quality of bottom sediments, the average annual values of organochlorine pesticides concentrations in the bottom sediments gathered during the field works were compared with the quality guidelines. There are no approved quality guidelines for maximum permissible concentrations of pollutants in bottom sediments in the Russian Federation. For this reason, we used the quality guidelines applied in foreign countries («Dutch sheets» (Neue Niederlandische Liste. NNL) and Canadian quality standards for marine and estuarine bottom sediments (Canadian Sediment Quality Guidelines, CSQGs). Possible sources of organochlorine pesticides in the marine environment were analyzed. The results of this work showed that despite the ban on the use of these substances, these pesticides are included in the multiple compounds used in different industries and continue to enter and accumulate in the marine environment.

Background: Autism spectrum disorder (ASD) diagnoses have rapidly increased globally. Both environmental and genetic factors appear to contribute to the development of ASD. Several studies have shown a potential association between prenatal or postnatal pesticide exposure and the risk of developing ASD. Methods: We reviewed the available literature concerning the relationship between early life exposure to pesticides used in agriculture, such as organochlorines, organophosphates and pyrethroids, and ASD onset in childhood. We searched on Medline and Scopus for cohort or case–control studies published in English from 1977 to 2020. Results: A total of seven articles were selected for the review. We found a remarkable association between the maternal exposure to pyrethroid, as well as the exposure to organophosphate during pregnancy or in the first years of childhood, and the risk of ASD onset. This association was found to be less evident with organochlorine pesticides. Pregnancy seems to be the time when pesticide exposure appears to have the greatest impact on the onset of ASD in children. Conclusions: Among the different environmental pollutants, pesticides should be considered as emerging risk factors for ASD. The potential association identified between the exposure to pesticides and ASD needs to be implemented and confirmed by further epidemiological studies based on individual assessment both in outdoor and indoor conditions, including multiple confounding factors, and using statistical models that take into account single and multiple pesticide residues.

Pesticide content in the soil, water, and products of agriculture in the Zhytomyr region of Ukraine was examined, and the accumulation of organochlorine pesticides by freshwater bivalve mollusks was assessed. Storage facilities of the Zhytomyr region contain nearly 392.18 t of pesticides in 137 warehouses, of which 11 meet the requirements, 36 are tolerable, and 90 are in poor condition. In 2018–2019, pesticide content (dichlorodiphenyltrichloroethane (DDT), heptachlor, dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyldichloroethane (DDD), hexachlorocyclohexane (HCH)) was studied in soil and sediments in the Zhytomyr region. The content ranged from 0.0007 to 0.07 mg/kg, which is lower than MPC (0.1 mg/kg). The content of HCH, DDT, DDE, DDD, and heptachlor was at 0.0007–0.01 mg/dm3 levels in water bodies of the Zhytomyr region in 2018–2019, also lower than MPC. In some samples of soil, water and vegetables, the recorded levels of DDT and organophosphate pesticides Dragon, Dorpan, and Dursban exceeded MPC in 1.5–3.0 times. Traces of organochlorine pesticide Aldrin were found in soft tissues of bivalve mollusks and in the sediments of water bodies they inhabit. Recommendations are proposed to lower the pesticide content in the environment.

Determination of organochlorine pesticide residues in shrimp is very important to ensure the consumer’s safety and to fulfill the importer’s demand. Therefore, a simple and efficient multiple organochlorine pesticide residues analytical method using quick, easy, cheap, effective, rugged and safe (QuEChERS) extraction technique and Gas Chromatography coupled with Electron Capture Detector (ECD) has been developed and validated for the determination of 19 organochlorine pesticides (α- BHC, δ- BHC, β- BHC, γ- BHC, Heptachlor, Aldrin, Heptachlor Epoxide, γ- Chlordane, α- Chlordane, α- Endosulfan, 4,4 DDE, Dieldrin, Endrin, 4,4 DDD, β- Endosulfan, 4,4 DDT, Endosulfan sulphate, Methoxychlor, and Endrin Ketone) in shrimp. The method was validated by evaluating the accuracy, precision, linearity, limit of detection (LOD) and limit of quantification (LOQ). The average recoveries of the selected pesticides ranged from 84% to 106% with RSDr ≤ 14% in four fortification levels of 0.05, 0.1, 0.2 and 0.3 mg kg-1. The linearity was ≥ 0.996 for all of the selected pesticides with matrix matched calibration standards. The LOD ranged from 0.003 to 0.009 mg kg-1 and the LOQ was 0.05 mg kg-1. This method was applied successfully for the residue analysis of 40 shrimp samples collected from different regions in Bangladesh.SAARC J. Agri., 16(1): 81-93 (2018)

DMT2 is the most common type of diabetes in the world. In developed countries, dia¬betes affects people over 65 years old. However, in Asia, the younger generation is also affected and the age onset of diabetes has declined. Several factors that may lead to early diabetes is changes in consumption and activity patterns. However, that should be noted that pestisides expusure by food and environmental pollutants can even be the reason behind the increasing incidence of type-2 diabetes mellitus. This study aims to provide a systematic review of the impact of pesticide exposure on the incidence of type-2 diabetes, especially at a young age. We performed articles search using Science Direct, Spinger Link, ProQuest, Pubmed and Scopus databases published since 2010 until 2020. In total, 10 scientific articles included in this study. Pesticide exposure is determined by the nature of the sources. Most studies showed a strong association between organochlorine pesticides and also the incidence of diabetes. The average age of the entire study was 43 years this has proven that there is a decrease in the onset of age of people with DMT2 in Asia. The results show that organochlorine pesticides had an impact on the incidence of DMT2 at a younger age. Someone with high levels of organochlorines serum will had a high blood glucose levels. Race may also effect the incidence of diabetes, it need to be assessed experimentally.

Pesticides have been used in the continent for about eight decades. Major use has been in agriculture, livestock development, and disease vectors control. Recent international conventions have been made with little scientific data and information on the tropical situation. Rapid development of resistance to pesticides demands better scientific understanding of pest management. Tropical research data on organochlorine pesticides show rapid degradation pattern, low residue levels, and widespread distribution. Given the above, there is a need to factor into consideration tropical climatological calamities in any future pesticide policy. Continued use of pesticides is anticipated in the tropics.

ABSTRACT. In this study, the residual concentrations of some organophosphate and organochlorine pesticides were determined in tomato, potato, and pineapple samples from selected farmlands of Jimma and Kefa Zones, Southwest of Ethiopia. The QuEChERS procedure, AOAC-2007, was used for extraction of the pesticides from the samples prior to their determinations by a gas GC-ECD. Pesticides including dichlorodiphenyltrichloroethane, endrin, and dieldrin were not detected in all studied samples. Dimethoate was detected only in Mana and Saka Buyo Qacama tomato samples. Likewise, malathion was detected only in the Saka Buyo Qacama tomato sample. The residual concentrations of most of the studied pesticides were below their MRLs set in EU guideline. However, the recorded residual concentrations of dibutyl chlorendate and chloroflurenol-methyl pesticides were above the EU general default MRL. The percent recoveries studied by spiking known concentrations of the analytes ranged from 71.22–121.56%. However, the recoveries of chloroflurenol-methyl and chlorpyrifos in the potato sample were 65.65 and 67.90%, respectively. One-way ANOVA results (p ≤ 0.05) indicated the presence of significant variations in the concentrations of the detected pesticides among the sampling sites. Generally, the findings showed that regular monitoring of pesticide residues in agricultural products of the area is needed.

An important indicator of the safety of plant raw materials and herbal medicinal products is the content of residual pesticides. Its determination is particularly difficult in aromatic plants characterised by a diverse composition of terpenoids co-extracting with organochlorine pesticides and forming numerous degradation products that interfere with the analysis.The aim of the study was to develop and validate an analytical procedure for the quantification of organochlorine pesticides in plant raw materials containing terpenoids, compliant with the requirements of the State Pharmacopoeia of the Russian Federation.Materials and methods: the study analysed samples of morphologically different raw materials from 21 plant species containing terpenoids. The analysis was carried out by GLC-MS on a 450-GC gas chromatograph coupled to a 220-MS ion-trap mass spectrometer (Varian, USA) using a FactorFour VF-5ms quartz capillary column (30 m × 0.25 mm).Results: the authors developed the analytical procedure for organochlorine pesticides in medicinal plant raw materials containing terpenoids. Its specificity was confirmed by retention times and mass spectra for all the tested analytes. The recovery of pesticides was studied on model mixtures of a plant raw material and ranged from 70.04 to 99.27%. The authors established the linearity using a calibration curve for internal standard (4,4'-dibromodiphenyl) concentrations from 1.0 to 18.1 µg/mL. The procedure was linear across the entire studied range; the correlation coefficient equalled 0.999. The trueness and precision of the analytical procedure met the acceptance criteria.Conclusions: the analytical procedure has been put into use at the Testing Centre of VILAR. From 2018 to 2020, 63 samples of 21 types of medicinal plant raw materials were analysed and found to be corresponding to the safety requirements for the organochlorine pesticide content. Residual pesticides were detected in the medicinal plant raw materials in few sporadic cases.

This study reports the analysis of drinking water sources of river Krishni catchment, contaminated by organochlorine pesticides. Iron oxide nanoparticles had been synthesized through co-precipitation method and utilized for the degradation of organochlorine pesticides using advanced oxidation processes. The sharp and narrow peaks of X-ray diffraction patterns revealed the crystalline nature of synthesized iron oxide nanoparticles having size less than 100 nm. The nanoparticles were also characterized using TEM, UV-Vis and IR spectral analysis. Liquid-liquid extraction and GC-MS were used for the detection analysis of pesticides. GC-MS technique was used for further quantitative analysis of 19 pesticides. The degradation analysis showed the maximum amount of degradation (up to 98.38 %) of organochlorine pesticides.
