Available in PDF, EPUB and Kindle. Book excerpt: The major goals of this program were to develop preliminary survey information on the organophosphorus pesticide industry wastewater streams and to develop analytical methods to monitor levels of organic compounds present in these streams. The identification and quantification of organophosphorus compounds were emphasized, but nonphosphorus chemicals were also included in the survey. A secondary goal of the program was to use the survey information to evaluate the efficiency of various waste treatment processes. The wastewater from five pesticide plants that produced eight organophosphorus pesticides was sampled. The pesticides were: diazinon; methyl parathion; azinphos-methyl and disulfoton; fonofos, phosmet and benulide; and EPN. Samples were taken at pre-, mid- and posttreatment locations. The analytical methodology included extraction and partitioning, gas chromatography with specific element detection, thin-layer chromatography, infrared spectroscopy and gas chromatography/mass spectrometry. Methods and procedures were developed by analysis of (a) distilled water samples fortified with model compounds and (b) an actual wastewater sample from the azinphos-methyl/disulfoton production plant. The 116 compounds identified included organophosphorus pesticides, related organophosphorus esters, organophosphorus acids, volatile organic compounds, thiocarbamate pesticides, triazine herbicides, and miscellaneous extractable process chemicals, by-products, and compounds of unknown origin. The levels of parent pesticides in the final effluents were below 0.005 mg/liter. Oxygen analogs of the pesticides were not a significant degradation product of any of the waste treatment processes. Phosphorothioates and organophosphorus acids were only partially removed by the treatment processes, and were observed the parts per million levels in some final effluents. Phenylphosphonate esters closely related to the parent pesticides were observed in a final effluent sample at parts per billion levels. Volatile organic compounds were effectively removed by the treatment systems with the exception of one totally enclosed system. One effluent which was disposed in an injection well contained over 150 mg/liter organic disulfides, almost 200 mg/liter thiocarbamate pesticides and over 100 mg/liter organophosphorus acids. Recommendations were made regarding further work in treatment system evaluation, synergistic toxicity studies of organophosphorus compounds, analytical mehtod development, and the fate of wastewater in injection well systems.

Book Synopsis Microbial Degradation of Xenobiotics by : Shree Nath Singh
Download or read book Microbial Degradation of Xenobiotics written by Shree Nath Singh and published by Springer Science & Business Media. This book was released on 2011-10-07 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our interest in the microbial biodegradation of xenobiotics has increased many folds in recent years to find out sustainable ways for environmental cleanup. Bioremediation and biotransformation processes harness the naturally occurring ability of microbes to degrade, transform or accumulate a wide range of organic pollutants. Major methodological breakthroughs in recent years through detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms have provided us unprecedented insights into key biodegradative pathways and the ability of organisms to adapt to changing environmental conditions. The degradation of a wide spectrum of organic pollutants and wastes discharged into the environment by anthropogenic activities is an emerging need today to promote sustainable development of our society with low environmental impact. Microbial processes play a major role in the removal of recalcitrant compounds taking advantage of the astonishing catabolic versatility of microorganisms to degrade or transform such compounds. New breakthroughs in sequencing, genomics, proteomics, bioinformatics and imaging are generating vital information which opens a new era providing new insights of metabolic and regulatory networks, as well as clues to the evolution of degradation pathways and to the molecular adaptation strategies to changing environmental conditions. Functional genomic and metagenomic approaches are increasing our understanding of the relative importance of different pathways and regulatory networks to carbon flux in particular environments and for particular compounds. New approaches will certainly accelerate the development of bioremediation technologies and biotransformation processes in coming years for natural attenuation of contaminated environments

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of some organophosphate insecticides and herbicides, including diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos. Diazinon acts on a wide range of insects on crops, gardens, livestock, and pets, but most uses have been restricted in the USA, Canada, and the European Union since the 1980s. Glyphosate is the most heavily used agricultural and residential herbicide in the world, and has been detected in soil, air, surface water, and groundwater, as well as in food. Malathion is one of the oldest and most widely used organophosphate insecticides, and has a broad spectrum of applications in agriculture and public health, notably mosquito control. The insecticide parathion has been largely banned or restricted throughout the world due to toxicity to wildlife and humans. Tetrachlorvinphos is banned in the European Union, but continues to be used in the USA and elsewhere as an insecticide on animals, including in pet flea collars. The IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of these agents.

This book was released on 2018-04-30 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
