Synopsis Pesticides in the Atmosphere by : Michael S. Majewski
Most people know about the presence and health effects of pesticide residues in the water they drink. However, they may not realize the impact of atmospheric transportation and deposition of pesticides on water quality. Scientific studies of pesticides in various atmospheric matrices (air, rain, snow, aerosols, and fog) provide some of the answers.

Synopsis Fate of Pesticides in the Atmosphere: Implications for Environmental Risk Assessment by : Harrie F.G. van Dijk
Global pesticide use is currently estimated at approximately 2. 5 billion kg per year (Pimentel eta/. , 1998). To be effective, pesticides need to persist for a certain period of time. However, the longer their persistence, the greater the potential for transport of a fraction of the amount applied away from the target area. Pesticides are dispersed in the environment by water currents, wind, or biota. Pesticides can directly contaminate ground and surface waters by leaching, surface run-off and drift. Pesticides can also enter the atmosphere during application by evaporation and drift of small spray droplets, that remain airborne. Following application, pesticides may volatilise from the crop or the soil. Finally, wind erosion can cause soil particles and dust loaded with pesticides to enter the atmosphere. The extent to which pesticides enter the air compartment is dependent upon many factors: the properties of the substance in question (e. g. vapour pressure), the amount used, the method of application, the formulation, the weather conditions (such as wind speed, temperature, humidity), the nature of the crop and soil characteristics. Measurements at application sites reveal that sometimes more than half of the amount applied is lost into the atmosphere within a few days (Spencer and Cliath, 1990; Taylor and Spencer; 1990; Van den Berg et a/. , this issue).

Synopsis Pesticides by : Hamir S. Rathore
Pesticides play an important role in controlling pests that carry diseases and threaten crop production. In recent years, however, there has been increased concern about the adverse impacts of pesticides and their degradation products on public health and the environment. A considerable amount of work is being done to develop nonchemical methods of

Synopsis Pesticides in the Soil Environment by : Shahamat U. Khan
Fundamental Aspects of Pollution Control and Environmental Science, 5: Pesticides in the Soil Environment focuses on the effects of pesticide use on the quality of soil. The manuscript first offers information on the classification of pesticides and physicochemical processes affecting pesticides in soil. Topics include herbicides, fungicides, movement in soil, chemical conversion and degradation, and photodecomposition. The text then elaborates on microbial processes affecting pesticides in soil, including fumigants, fungicides, and insecticides. The text examines the occurrence and persistence of pesticide residues in soil and minimizing pesticide residues in soil. Discussions focus on persistence, bound residues, plant uptake, short residual residues, and eliminating pesticide residues. The text is a dependable reference for readers interested in the effects of pesticide use on the quality of soil.

Synopsis Pesticides, Organic Contaminants, and Pathogens in Air by : James N. Seiber
The air is an important but largely unrecognized source of contaminant fate in the environment, including transport of pesticides and contaminants to nontarget areas and exposures for people and wildlife. This book summarizes and places in perspective the potential transport, transformation, and health implications of pesticides and contaminants in air, including the air we breathe. It delves into the hypothesis that the atmosphere is the most significant environmental compartment affecting the overall transport and fate of many classes of environmental contaminants. The authors draw parallels between sampling, analysis, and impact of airborne toxics and particulate matter with the COVID-19 pandemic. Airborne viruses and fine particulate matter, which are of similar size, have remarkable parallels in how they are transmitted and accumulated in the respiratory tract. FEATURES Assesses exposures of people and wildlife to airborne chemicals Includes case study applications, with relevant data summarized for pesticides and contaminants in air Discusses approaches to modeling pesticides’ and contaminants’ dispersion and fate in air Includes an assessment of the physicochemical properties of pesticides and contaminants that influence sampling and atmospheric mobility and fate The authors are global experts in air contaminant research, and this book is well organized and helpful for people interested in regulatory, health, and other topics related to pesticides and contaminants in air. James N. Seiber is a Professor Emeritus at the University of California, Davis. Thomas M. Cahill is an Associate Professor in the School of Mathematical and Natural Sciences at Arizona State University.
