Download or read book Organophosphate Pesticide Degradation Under Drinking Water Treatment Conditions written by Stephen E. Duirk and published by . This book was released on 2005 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little work to date has solely investigated the kinetics and pathways of pesticide transformations under drinking water treatment conditions. Free chlorine has been found to react with s-triazine, carbamate, and organophosphate pesticides. However, these experimental conditions did not account for naturally occurring aquatic constituents such as natural organic matter (NOM) or inorganic ions (i.e., bromide). The kinetics and degradation pathways for chlorpyrifos (CP), an OP pesticide, have been established in buffered deionized water. However, the effect of NOM and bromide on the rate of CP has yet to be thoroughly investigated. This research was designed to examine the influence of NOM and bromide on the loss of CP in the presence of free chlorine.

Download or read book Formation and Removal of Pesticides and Pesticide Transformation Products During Water Treatment written by Evelyn F. Chamberlain and published by . This book was released on 2008 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A comprehensive suite of over 60 pesticides (herbicides, insecticides, and fungicides) representing a variety of classes at environmentally relevant concentrations (low [mu]g/L) were screened for reactivity under typical drinking water conditions and dosages. The most common oxidants/transformation agents in water treatment systems were examined for reactivity including free and combined chlorine, chlorine dioxide, permanganate, ozone, hydrogen peroxide, ultraviolet radiation, and high pH (alkaline hydrolysis). Due to the broad nature of the study, pesticide compounds were analyzed as multiple mixes broken into two groups based on analytical methods, those analyzed by GC/ECD and those by LC/MS. Combinations of reactive disinfectant/oxidant and pesticide most likely to lead to significant degradate formation within water utilities were quantitatively identified. Results from the screening study portion of this work were prioritized based on reactivity, anticipated occurrence, anticipated toxicity implications, and other considerations. The most important systems were then studied in detail to determine major degradation products, kinetic rates, and other information specific to the disinfectant/oxidant - pesticide combination. One detailed system in particular, fipronil and several commonly utilized oxidants, was investigated. Findings indicate that fipronil is readily degraded by free chlorine, chlorine dioxide and permanganate but not by monochloramine. Furthermore, permanganate oxidation produces a degradation byproduct, fipronil sulfone, which accumulates within the system if no other oxidant is utilized. This body of work provides highly valuable information on the most reactive oxidant/pesticides systems, signifying the highest potential for degradation formation. Additionally, detailed information on a widely used insecticide is supplied. This work helps to direct future research and provides treatment facilities guidance as to relative removals of problematic pesticide compounds as well as an initial alert to future potential problems arising from degradate formation"--Abstract, leaf iv.

Download or read book Bioremediation of Industrial Waste for Environmental Safety written by Gaurav Saxena and published by Springer. This book was released on 2019-06-29 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Achieving environmental sustainability with rapid industrialization is a major challenge of current scenario worldwide. As globally evident, industries are the key economic drivers, but are also the major polluters as untreated/partially treated effluents discharged from the industries is usually thrown into the aquatic resources and also dumped unattended. Industrial effluents are considered as the major sources of environmental pollution as these contains highly toxic and hazardous pollutants, which reaches far off areas due to the medium of dispersion and thus, create ecological nuisance and health hazards in living beings. Hence, there is an urgent to find ecofriendly solution to deal with industrial waste, and develop sustainable methods for treating/detoxifying wastewater before its release into the environment. Being a low cost and eco-friendly clean technology, bioremediation can be a sustainable alternative to conventional remediation technologies for treatment and management of industrial wastes to protect public health and environment. Therefore, this book (Volume I) covers the bioremediation of different industrial wastes viz. tannery wastewater, pulp and paper mill wastewater, distillery wastewater, acid mine tailing wastes, and many more; which are lacking in a comprehensive manner in previous literature at one place. A separate chapter dedicated to major industries and type of waste produced by them is also included. This book will appeal to students, researchers, scientists, industry persons and professionals in field of microbiology, biotechnology, environmental sciences, eco-toxicology, environmental remediation and waste management and other relevant areas, who aspire to work on the biodegradation and bioremediation of industrial wastes for environmental safety.

Download or read book Pesticides in the Diets of Infants and Children written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.
