Book Description
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.

Book Description
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.

Book Description
The Global Politics of Pesticides explores the varied, and often conflicting, interests involved in the formulation of international policies on chemical pesticide manufacture and use in each of the main areas of environmental pollution, trade, development, public health, food security, biotechnology and industrial safety and explains why some aspects of pesticide use are subject to strict international guidelines whilst others are not. The book breaks new ground in objectively examining the competing viewpoints of food producers and other pesticide users, the chemical industry, health officials, traders, environmental/consumer pressure groups and the public. It also considers how international regulation can occur in spite of the fundamental differences of opinion and seemingly opposing interests held by the key actors.

Book Description
Chemical pesticides continue as a point of major controversy in our society. Increasingly stringent regulatory actions on the part of state and federal agencies, exemplified by the RPAR (Rebuttable Presump tion Against Registration) program of the Environmental Protection Agency, are supported by environmental groups and are generally op posed or viewed with skepticism by agriculturalists. The energy crisis invokes other questions on benefits of pesticides versus nonchemical controls and effects on labor utilization. As DDT and other persistent pesticides have been phased out, the more labile, short-lived chemicals have filled the voids in pest management systems; and effects on nontarget species appear to have declined in recent years as the shift occurred. However, nagging ques tions of the hazard to man and other nontarget species from long-term, low-level exposure to pesticides are frequently raised; and recent suggestions that certain well-known and long-used chemicals cause cancer, increase sterility, and initiate or augment other deleterious effects in test animals have instilled a sense of caution and raised con cern about the continued availability of some pesticides previously considered safe. So the facade of concern and confusion continues. This book is an outgrowth of a symposium at the meeting of the American Association for the Advancement of Science in February, 1978. An introduction has been added, and some of the papers have been modified since presentation.
