Abstract:
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.

Abstract:
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:
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.

Abstract:
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:
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:
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.

Abstract:
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.

Abstract:
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.

Abstract:
Organochlorine pesticides (OCPs) were extensively applied in agriculture, industry and public health programs for decades. Based on the persistence and the lipophilicity of OCPs, these chemicals are ubiquitous in the environment and can be accumulated in fatty tissues of animals through the food chain. Even being restricted for years, OCPs are still detected in human bodies. In this thesis, analytical methods for the determination of OCPs were developed and applied for the analysis of cord serum samples. The evaluation of prenatal exposure to OCPs and its effects on birth outcomes as well as the postnatal growth were investigated. Due to the toxicology and carcinogenesis, biomonitoring of the OCP exposure to human is needed. Therefore, an analytical method with high sensitivity and specificity is required to detect OCPs at trace levels in serum. We compared two data acquisition modes of mass spectrometry (MS), namely selected ion monitoring (SIM) and multiple reaction monitoring (MRM). Higher sensitivity and selectivity were achieved by MRM because the background noise was reduced by lowering the matrix effects. Different ionization techniques, including electron ionization (EI), chemical ionization (CI) and atmospheric pressure chemical ionization (APCI) were evaluated. The EI source is a universal ionization technique available with the MS library for the compound identification. The negative chemical ionization (NCI) is more suitable to analyze compounds with high electronegativity. The novel ionization technique APCI was coupled to gas chromatography-tandem mass spectrometry (GC-MS/MS). The APCI source was evaluated by terms of ionization and fragmentation performance. APCI was a soft ionization technique generating molecular ions with high intensity. The selectivity and sensitivity of APCI were comparable or better than the EI source. As one of the largest consumers and producers of OCPs, China has suffered severe OCP pollution. Previous monitoring studies reported detectable levels of OCPs in human bodies. However, studies concerning the prenatal exposure to OCPs in China are limited. Due to the vulnerability of fetuses, the effects of prenatal exposure to OCPs could be more severe than those of adults. We collected cord serum samples during the delivery period in Wuhan, China and measured the OCP concentrations to assess the prenatal exposure by using GC-MS/MS. Compared with other areas in China, the OCP levels in Wuhan were comparable in this population. The identified predominant OCPs were β-HCH and p,p'- DDE, with geometric means of 8.67 and 33.9 ng/g lipid, respectively. Slight positive associations were found between α-HCH and β-HCH, and between o,p′- DDT and p,p′-DDT, which indicated similar exposure source of these chemicals. The obtained results showed that HCH levels were associated with maternal age, body mass index (BMI) before pregnancy, education levels, and passive smoking. Associations between the prenatal exposure of OCPs and birth outcomes were investigated. The sex-specific relationships between the OCP exposure and birth size were indicated. Concentrations of β-HCH were inversely associated with birth weight and ponderal index for boys, while for girls these associations were not significant. Our results suggested that the prenatal exposure to OCPs exerted negative effects on the fetal growth, and precautions should be taken even though the OCP levels were relatively low.

Abstract:
The Trinity River passes through the Dallas-Fort Worth metroplex receiving point and non-point source contaminant loadings. Lepomis spp. were collected at twelve sampling locations in the Trinity River in August 1987 and September 1988 and analyzed for organochlorine pesticides and heavy metals. Results from the study were compared to existing U.S. FDA action and tolerance levels, LC50s, and historical data. Various longitudinal trends and some concentration patterns were observed. Continual study of pesticide and metal body burdens in fish allow testing for trends, and thereby, lead to a better understanding of the distribution of contaminants in the Trinity River.

Abstract:
In the past, it was widely assumed that deep drainage and the resultant movement of salts, nutrients and organochlorine pesticides was negligible in Vertosols (self-mulching grey and brown clays, and black earths) of the Lower Namoi Valley, New South Wales, Australia. Recent research however has shown that in fact deep drainage does occur. The main concern, therefore, is their movement beyond the reach of crop roots. Groundwater systems in the Lower Namoi Valley have been reported to be declining, suggesting that deep drainage is not reaching groundwater. Accumulation of salts, nutrients and organochlorine pesticides (OCP’s) may, therefore, be occurring below the root zone in particular regions of the Lower Namoi Valley. The objective of this study was to estimate deep drainage using chloride mass balance models and quantify the salt, nutrient and OCP movement under selected management systems in irrigated Vertosols sown with cotton. Four experimental sites were established to study deep drainage and the movement of salts, nutrients and OCP’s in irrigated Vertosols; one at the Australian Cotton Research Institute (ACRI) Myall Vale, another near Wee Waa, a third at Merah North, which has a sodic sub-soil, and a fourth near Narrabri, which is irrigated with treated sewage effluent.

Abstract:
This study evaluated levels for organochlorine pesticides (DDTs, HCHs, Heptachlors, Aldrins and Endosulfanes), their residues, polychlorinated biphenyls (PCB) and poly aromatic hydrocarbons (PAH) in water samples of Adriatic Sea, Albanian part. Water stations were chosen near the main river estuaries of Albania (Vjosa, Semani, Shkumbini, Erzeni, Mati and Buna rivers). These rivers have catchment areas that cover almost all Albania. First, agricultural, industrial and urban waste is transported in these rivers and after that they finished in Adriatic Sea. Water samples were analyzed for a five-year period from February 2015 to December 2019. Liquid-liquid extraction was used to isolate chlorinated pollutants and a florisil column was used for clean-up procedure. Analysis of organochlorine pesticides (according to Method EPA 8081B) and 7 PCB markers was realized using GC/ECD and RTX-5 capillary column. The PAHs were isolated by liquid-liquid extraction technique and after sample concentration qualitative and quantitative analyses were performed by the GC/FID technique. Organochlorine pollutants were detected for all stations of Adriatic Sea because of new arrivals by agricultural and industrial activity in river basins. The highest levels were found near Shkumbini and Semani estuaries due to impact Myzeqeja agricultural area. New arrivals from water irrigation and rainfall influence in found levels. Degradation products of pesticides and volatile PCBs were found at higher levels for all samples analyzed. The levels of some individual organochlorine pesticides were higher than EU and Albanian norms for Semani and Shkumbini rivers. Also, PAHs were found at higher levels for Semani River because of extracting-processing industry in Patos-Marinza area. Monitoring of organic pollutants in water of Adriatic Sea should be continuous because of its importance in fishing, tourism, recreation and Albania economy overall.

Abstract:
The overall theme of this project was to increase the speed of analysis for monitoring pesticide residues in food. Traditionally, analytical methods for multiple pesticides are time-consuming, expensive, laborious, wasteful, and ineffective to meet critical needs related to food safety. Faster and better methods were needed to provide more cost-effective detection of chemical contaminants, and thus provide a variety of benefits to agriculture. This overarching goal to speed and improve pesticide analysis was successfully accomplished even beyond what was originally proposed by the investigators in 1998. At that time, the main objectives of this project were: 1) to further develop a direct sample introduction (DSI) device that enables fast sampling and introduction of blended-only agricultural products for analysis by gas chromatography (GC); 2) to evaluate, establish, and further develop the method of simultaneous pulsed flame photometric detector (PFPD) and mass spectrometry (MS) detection for enhanced pesticide identification capabilities; and 3) to develop a new and novel MS pesticide analysis method, based on the use of supersonic molecular beams (SMB) for sampling and ionization. The first and third objectives were successfully accomplished as proposed, and the feasibility of the second objective was already demonstrated. The capabilities of the GC/SMB-MS approach alone were so useful for pesticide analysis that the simultaneous use of a PFPD was considered superfluous. Instead, the PFPD was investigated in combination with an electron-capture detector for low-cost, simultaneous analysis of organophosphorus and organochlorine pesticides in fatty foods. Three important, novel research projects not originally described in the proposal were also accomplished: 1) development of the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticides in foods; 2) development and optimization of a method using low-pressure (LP) GC/MS to speed pesticide residue analysis; and 3) innovative application of analyte protectants to improve the GC analysis of important problematic pesticides. All of the accomplishments from this project are expected to have strong impact to the analytical community and implications to agriculture and food safety. For one, an automated DSI approach has become commercially available in combination with GC/MS for the analysis of pesticide residues. Meanwhile, the PFPD has become the selective detector of choice for the analysis of organophosphorus pesticides. Great strides were made in SMB-MS through the manufacture of a prototype "Supersonic GC/MS" instrument, which displayed many advantages over commercial GC/MS instruments. Most notably, the QuEChERS method is already being disseminated to routine monitoring labs and has shown great promise to improve pesticide analytical capabilities and increase lab productivity. The implications of these developments to agriculture will be to increase the percentage of food monitored and the scope of residues detected in the food, which will serve to improve food safety. Developed and developing countries alike will be able to use these methods to lower costs and improve results, thus imported/exported food products will have better quality without affecting price or availability. This will help increase trade between nations and mitigate certain disputes over residue levels in imported foods. The improved enforcement of permissible residue levels provided by these methods will have the effect to promote good agricultural practices among previously obstinate farmers who felt no repercussions from illegal or harmful practices. Furthermore, the methods developed can be used in the field to analyze samples quickly and effectively, or to screen for high levels of dangerous chemicals that may intentionally or accidentally appear in the food supply.
