The work describes a study of the possibility of removal of organo-phosphorus insecticide quinalphos and organochlorine herbicide lindane from water by using the biofilm formed on active carbon. It was established that two similtaneous processes took place in the biosorption column - adsorption and microbiological degradation of the adsorbed matter. At the shock concentrations of lindane in the influent, an inhibition of microbiological processes in the biofilm occurred. It was observed that the biosorption system was more efficient in the removal of the organo-phosphorus insecticide than of the organo-chlorine herbicide.

Abstract A simple method for determination of 5 organo phosphorus pesticides (dimethoate, chlorfenvin phos, chlorpyrifos, methidathion, and phosmet) in molluscs (Mytilus galloprovincialis and Venus gallina) was developed, with special attention to cleanup. Organophosphorus pesticides were extracted with acetonitrile-acetone (90 + 10, v/v) in a high-speed blender. Two cleanup procedures were used to defat extracts prior to injection into a gas chromatograph: liquid-liquid partition with acetoni trile-hexane and adsorption column chromatography with silica gel. The latter was more efficient for elimination of fat and fractionation of pesticides with different polarities. Limits of detection of the overall procedure including extraction and cleanup ranged from 0.2 to 1 ng/g. Quantitative recoveries for pesticide concentrations ranging from 1 to 10 000 ng/g were obtained.

Abstract The paper presents results of analyses of 4182 samples collected from January 1995 to December 1996 for the Danish National Pesticide Monitoring Program. The program basis is a random sample control supplemented with a target control. The objectives of the control are to monitor consumer exposure to health hazards and to enforce national and European Community regulations. The Danish Veterinary and Food Administration is responsible for establishing methods, data manipulation, and evaluation, but actual analyses are performed at 4 regional laboratories. In addition to a description of the Danish National Pesticide Monitoring Program on food, the effects of lowering the reporting limits are discussed. Pesticides included are those in current use as well as chlorinated pesticides like lindane, DDT, and HCB, occurring in food now primarily as a result of environmental contamination. Commodities analyzed are fruits, vegetables, cereals, bran, fish, and animal products such as meat, butter, cheese, fat, and eggs. In fruits and vegetables, residues were detected in 10% of 2515 samples, with higher incidences of detection for foreign commodities. Violation rate was 0.6%. In food of animal origin, low levels of organo- chlorine pesticides were detected in most fish samples and in more than half of the animal product samples. However, no results exceeding maximum residue limits were found. No residues of organo- phosphorus pesticides were detected in the 231 meat samples analyzed.

Abstract Gas chromatographic (GC) analysis of 6 organo-phosphorus pesticides (methamidophos, acephate, omethoate, diazinon, dimethoate, and chlorpyrifos) was performed with cool on-column, splitless, and pulsed splitless injections and with nitrogen–phos phorus or mass-selective detection. The pulsed splitless technique uses a high column flow rate during injection to sweep the sample out of the inlet rapidly, reducing analyte loss due to adsorption or thermal decomposition. After injection, the column flow rate is automatically reduced to normal values for chromatographic analysis. Pesticide recoveries for splitless and pulsed splitless injections were determined by comparison of GC peak areas with those obtained with cool on-column injection. With conventional splitless injection at a column flow rate of 5 mL/min, recoveries of acephate, omethoate, and methamidophos were only 57, 63, and 71 %, respectively. Pulsed splitless methods with very fast injection flow rates dramatically improved recoveries, with all 6 pesticides falling in the 97–102% range. Because column flow rates are much less for GC with mass spectral detection (GC/MS), recoveries with splitless injection were lower and improvements with pulsed splitless injection were less dramatic for GC/MS. When splitless injection was used, recoveries of the 6 pesticides spiked into a green bean matrix were better than those of pesticides dissolved in pure solvent, presumably because matrix compounds compete with pesticides for active sites in the inlet. By using pulsed splitless injection of solvent standards with very fast initial column flow rates, systematic analyte losses in the inlet were eliminated, making recoveries of pesticides from solvent and green bean matrix very similar.

A multiresidue method was developed and validated for simultaneous determination of 11 organochlorines, 8 synthetic pyrethroids and 14 organophosphorous pesticides in green gram and black gram grain samples using gas chromatography - electron capture detector and flame thermoionic detector (GC-ECD/FTD). The QuEChERS principle based methodology was adopted for extraction. Samples were extracted with acetonitrile and the co-extractives were removed using dispersive solid-phase extraction (dispersive-SPE) with primary secondary amine (PSA) after salting out with NaCl and MgSO 4 . Average recoveries for all the pesticides studied were between 71.70 and 113.31 % and relative standard deviation (RSD) ranged between 0.10 and 12.79 %. The present study indicates that the proposed method is useful in monitoring Organic Chlorine, Synthetic Pyrethroids and Organo Phosphorus insecticides in selected pulse grains.

The paper presents the data on the influence of remote consequences separate, combined and cumulative impact of agrochemicals (fertilizers and pesticides) on female mortality (1997-2006) from malignant tumors of the genitalia in the rural areas of the Republic of Dagestan. The intensive use of agrochemicals before 1995 exceeded the critical load level according to data of V.I. Polchenko and co-authors (3.93 kg/ha) and the classification of World Health Organization (4,0-5,0 kg/ha) in ten times and more. As objective quantitative indicators of the intensive use of pesticides and mineral fertilizers were applied territorial load and range of index territorial load of pesticides. To assess the environmental significance separate, combined and cumulative impacts of priority anthropogenic co-factors the author carried out predominantly two-factor analysis of variance. The share of influence, correlation coefficient and the Fisher test for each factor separately, but also for its combined and cumulative actions were calculated. It is shown the existence of significant correlation mortality from genital cancer with total territorial load of mineral fertilizers. The more significant the influence of factors on mortality was identified in terms of the total impact of the assortment index territorial load of organo-phosphorus compounds and copper-containing pesticides. It allows to considering them as secondary factors of cancer risk of death for women in rural areas.

Annotation:

Organophosphate (OP) poisoning is a health issue worldwide with over 200,000 deaths per year. Although not a problem in most developed countries, in some third world countries, one third of a hospital’s population could be patients with OP exposure. Even with the most aggressive therapy, 10-40% of patients admitted to an intensive care unit will die. Research into the best practice for treating OP poisoning is lacking, due somewhat to a lack of detailed understanding of the physiology of OP poisoning. Our research uses animal models of acute OP poisoning to explore the mechanism of OP-induced respiratory failure. Our research shows that animals poisoned with dichlorvos demonstrated a uniformly fatal central apnea that, if prevented, was followed immediately by a variable pulmonary dysfunction. Potential mechanisms for dichlorvos-induced central apnea can be divided into direct effects on the central respiratory oscillator (CRO) and feedback inhibition of the CRO. Two afferent pathways that can induce apnea include vagal feedback pathways and feed-forward pathways from the cerebral hemispheres. In our studies we found that vagal feedback and feed forward inhibition from the cerebral hemispheres were not required for OP-induced central apnea. The pre-Botzinger complex in the brainstem is thought to be the kernel of the CRO, but exposure of the pre-Botzinger complex to dichlorvos was not sufficient for apnea. Although OP induced central apnea was uniformly fatal, partial recovery of the CRO occurred post apnea with mechanical ventilation. Central apnea was ubiquitous in our rat poisoning model, but pulmonary dysfunction was extremely variable, with a range of pulmonary effects from fulminate pulmonary failure with prominent pulmonary secretions to no pulmonary dysfunction at all. Vagal efferent activity is involved in neural control of pulmonary tissue but the vagus was not involved in OP-induced pulmonary dysfunction. Anti-muscarinic medications are the mainstay of clinical therapy and are commonly dosed by their effects on pulmonary secretions. Our studies found that atropine (the most common therapeutic agent for OP poisoning) resulted in a ventilation-perfusion mismatch secondary to effects on the pulmonary vasculature.

As the world’s population is increasing rapidly, there is an urgent need to increase crop production. To achieve this goal, an eco-friendly alternative to chemical fertilizers and pesticides is required. Several types of microbes have been identified inhabiting the plant rhizosphere, such as nitrogen-fixing bacteria, plant growth promoting rhizobacteria, fungi, proteobacteria, mycoparasitic and mycorrhizal fungi. These microorganisms not only influence the growth and development of plants but also suppress pathogenic microbes near plant roots through several different mechanisms. Non-symbiotic microbes play a crucial role in the biogeochemical cycling of organic and inorganic phosphorus (P) near the root zone via solubilization and mineralization of P from total soil phosphorus. Additionally, some non-pathogenic microbes have also been reported to induce systemic resistance in plants, which is phenotypically similar to pathogen-induced systemic acquired resistance (SAR). The present review summarizes the latest knowledge on the role of non-pathogenic strains of microbiomes residing in the rhizosphere and their commercial applications.

Organic biodegradable waste contributes to environmental pollution in the Democratic Republic of Congo (DRC). Composting, pyrolysis, and mycorrhization are technologies used to recover this waste into biofertilizers and biopesticides, alternative to chemical fertilizers and pesticides that have significant economic and ecological footprints. Biological waste recovered in this way is climatic game and agricultural potential. Biochar Kahambwe with high carbon content (46.5%), proves to be a carbon sink and a considerable pedogenetic factor. Biochar Kahambwe, due to its alkaline pH (8.6), acts as a limestone amendment for the acidity of tropical soils. Biochar Kahambwe with a high cation exchange capacity (46.3%) is a source of nutrients including nitrogen (3.8%), phosphorus (0.59%), and potassium (0.20%) as well as the water stored in its pores (Water Binding Capacity: θv = 0.035 cm3.cm3; pF = 1.25) which also serve as ecological niches for bacteria (Azotobacter, Nitrobacter, Nitrosomonas), Arbuscular Mycorrhizal Fungi (Glomus, Gigaspora). In the process of composting and mycorrhization of biochar, the respective values of the Stability Indices of Organic Materials are 45%, 60%, 60%, and 80%, respectively, for manure composts, pig manure, household waste composts, and sawdust composts.

Annotation:

The 20thcentury witnessed an augmentation in agricultural production, mainly through the progress and use of pesticides, fertilizers containing nitrogen and phosphorus, and developments in plant breeding and genetic skills. In the naturally existing ecology, rhizospheric soils have innumerable biological living beings to favor the plant development, nutrient assimilation, stress tolerance, disease deterrence, carbon seizing and others. These organisms include mycorrhizal fungi, bacteria, actinomycetes, etc. which solubilize nutrients and assist the plants in up taking by roots. Amongst them, arbuscular mycorrhizal (AM) fungi have key importance in natural ecosystem, but high rate of chemical fertilizer in agricultural fields is diminishing its importance. The majority of the terrestrial plants form association with Vesicular Arbuscular Mycorrhiza (VAM) or Arbuscular Mycorrhizal fungi (AMF). This symbiosis confers benefits directly to the host plant’s growth and development through the acquisition of Phosphorus (P) and other mineral nutrients from the soil by the AMF. They may also enhance the protection of plants against pathogens and increases the plant diversity. This is achieved by the growth of AMF mycelium within the host root (intra radical) and out into the soil (extra radical) beyond. Proper management of Arbuscular Mycorrhizal fungi has the potential to improve the profitability and sustainability of agricultural systems. AM fungi are especially important for sustainable farming systems because AM fungi are efficient when nutrient availability is low and when nutrients are bound to organic matter and soil particles.

Conventional agriculture plays a substantial role in meeting the food demands of a growing human population, which has led to an increased reliance on chemical fertilizers and pesticides. Chemical fertilizers are industrially manipulated substances and composed of known amount of nitrogen, phosphorus and potassium. In appropriate and misuse use of chemical fertilizers causes air and ground water pollution by eutrophication of water bodies and causing health problem in human. Therefore, the aim of this chapter is to emphasize the importance and use of plant growth promoting bacteria (PGPB) as a gateway to sustainable agriculture that could ensure plant productivity and quality agricultural practices in an environment friendly manner. In this respect, efforts have been made to products of nutrient rich high-quality food in feasible way to ensure bio-safety. The innovative aspect of farm production attracts the need of biological based organic fertilizers, an exclusive alternative to agro-chemicals. Organic farming is one of such strategies that not only ensures food safety but also adds to the biodiversity of soil. The eco-friendly approaches trigger a wide range of application of PGPB that leads to improved plant growth, soil health, nutrient uptake and plant tolerance to abiotic and biotic stress. PGPB is an essential component of organic farming and play crucial role in maintaining long term soil fertility and sustainability and would be a viable alternative for farmers to increase productivity per unit area in organic farming for an era of prosperity and clean environment.

Annotation:

Phosphorus (P) is an essential nutrient for plants and animals because of its vital role in energy transformation processes such as photosynthesis and glycolysis. Soil is the primary source of P for plants (and animals), and while native soil P is mainly derived from the mineral apatite (Ca10(PO4)6(OH,F)2) present in soil parent material, supplementary P is added in fertilizers. In addition, large quantities of P are present in household and industrial chemicals such as detergents, and as a result organic wastes such as municipal sewage sludge contain significant amounts of various chemical forms of inorganic and organic P. The biogeochemical cycling of P in soil is determined by a complex interaction of chemical, biochemical and biological processes, which in turn are influenced by a variety of environmental and anthropogenic factors in natural and agro-ecosystems. It is clear that P is a key element in the environment; it is indispensable for plant growth, but its release into water bodies such as rivers and lakes can cause significant environmental damage as a result of eutrophication. The detailed chemical nature and associated transformations of P in the soil—plant system, and the fate of native and applied P in particular, must be fully understood in order to maximize the agronomic benefits of P while minimizing any adverse environmental impacts. The latter is particularly important in view of the growing importance of land application as a disposal option for organic wastes such as animal manures and municipal sewage sludge. The large gyromagnetic ratio of the 31P nucleus and its 100% natural abundance make 31P easy to detect by nuclear magnetic resonance (NMR) spectroscopy, and accordingly NMR has been used to examine P in a wide variety of environments. In particular, NMR spectroscopy has been shown to be a valuable tool for investigating the chemical nature and transformations of P in the soil environment and the associated fate of fertilizers, pesticides and organic wastes. This chapter includes a brief summary of the use of liquid-state 31P NMR to investigate the chemical nature and cycling of P in the soil-plant system and the fate of selected pesticides.

Olive (Olea europeae L.) is one of the most important fruit trees of the Mediterranean regions. Biotic factors such as phytopathogenic diseases have a significant negative impact on olive productivity in the Mediterranean Basin including Algeria. Currently, phytopathogens management is focus mainly on the use of chemical pesticides which is not recommended because it leads to environmental pollution, development of chemical resistance, and its low cost-efficiency. Eco-friendly methods and alternative disease control measures such as the use of biocontrol agents and biofertilizer should be opted as alternatives to the use of synthetic chemicals. Trichoderma species associated with olive roots are known for their ability to produce antimicrobial compounds, such as antibiotics, volatile organic compounds and lytic enzymes that restrict phytopathogenic strain growth. Besides, they are considered as plant growth promoting fungi (PGPF). This genus colonize the root systems of plants and promote their growth; it can increase nutrient availability and uptake in plants by fixing nitrogen, solubilizing phosphorus, producing several biomolecules and phytohormones. Moreover, it helps plants tolerate environmental stresses such as drought, salinity and diseases. In this work, we review pionnering and recent developments on several important biomolecules and functions that Trichoderma species isolated from olive rhizosphere soil exhibit to enhance plant growth and control phytopathogen diseases. Therefore, the use of highly competitive strains in open field in order to obtain consistent and better results in agricultural production activities.
