Pesticides have played a significant role in increasing food production, and in view of growing worldwide food demand we can expect the use of these chemicals to increase. However, some of them have found their way into the biosphere and have been classi fied as persistent toxic chemicals. This has resulted in serious concern about environmental contamination. Since we are going to continue using chemicals, we should learn more about such aspects as their transport in the environment, the relationship of their physical-chemical properties to transport, their persistence in the biosphere, their partitioning in the biota, and toxicological and epidemiological forecasting based on physical-chemical properties. Environmental chemodynamics is the name given to a subject which deals with some of the above topics, utilizing the principles of such disciplines as chemistry, physics, systems analysis, modelling, engineering, and medical and biological sciences. To ensure the safety of the environment, we must know more about the chemodynamical behavior of pesticides and related chemi cals. The purpose of the symposium "Environmental Dynamics of Pes ticides" was to explore the concept of chemodynamics as applied to pesticides and thus may help in developing the emerging field of environmental chemodynamics. The symposium was held during the l37th National American Chemical Society Meeting at Los Angeles, California, during April, 1974. The three sessions in the sym posium were chai'red by Drs. V.H. Freed, D.G. Crosby, and R. Haque.

This book brings together over 30 contributors with expertise in a variety of disciplines related to the topic. Although efforts continue toward reduction or elimination of pesticide chemicals in the management of pests in agriculture, public health and the urban arena, chemicals will continue to be one of the main weapons in control of insects, weeds, nematodes, plant diseases, etc. for some time to come. While considerable information is known about the acute toxicity of these compounds, information on the chronic effects from exposure to minute amounts of pesticide residues in food, water, air and soil is often very limited. This book approaches the topic from several different vantage points including pesticide epidemiology, new modes of action to minimize nontarget exposure, bioremediation of contaminated areas, molecular biology of the modes of action and detoxication of pesticides, and the dynamics of pesticide movement in the environment. As world leaders in the manufacture and use of pesticides, countries must cooperate in the search for safer pesticides with minimum chronic effects on humans and the environment. This book helps to remove the barriers of distance and language and should lead to new cooperative research efforts across country lines and discipline lines.

Discussing the range of effects of pesticides on food and human safety, water quality, wildlife, and pest management, this book explores the agricultural, economic, and regulatory factors that affect pesticide use. It examines crop and pest ecology, integrated pest management principles, and emerging analytical tools to improve the efficacy and cost-efficiency of pest control. Expert contributions describe the current status of pesticides issues and those related to pest management. The book summarizes advances and trends in the crop protection industry, such as integrated pest management, hybrid seed and generic pesticide production, improved pesticide formulations, and plant biotechnology.

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

Water covers about two-thirds of the surface of earth, but only 0.627 percent of this water is the sweet surface and subsurface water available for the survival of freshwater organisms including man (1,2). Some of this fresh or sweet water lies in practically uninhabitable regions (rivers: }1ackenzie in Canada; Amazon in Central America; Ob, Yenesey, and Lenta in Siberia, etc.). Also, most of the major rivers (the Mississippi in U.S.A., the Rhine in Europe, the Volga in U.S.S.R., the Ganges in India, etc.), because they flow through agricultural land or urban and industrial areas, have become highly contaminated with chemicals (3). This leaves us with shrinking resources of sweet surface water. In the United States, the dependable supplies of this water are already dwindling in cities like New York and Los Angeles and states like New Mexico and Texas (3).

Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.
