"A number of chemicals of diverse characteristics have arbitrarily been classed together on the basis of their use and given the descriptive name "pesticides." An unfortunate aura of mystery has developed about these chemicals. However, there is nothing unique or mysterious about the chemicals we refer to as "pesticides." Like other chemicals, they have properties which can be accurately measured; they obey all the laws of physics, chemistry, and biology. Chemical and physical properties of a pesticide and interacting environmental factors determine the behavior of pesticides. Behavior in turn dictates the ultimate fate of the pesticide (16). To predict behavior, we need to measure the chemical and physical properties of the pesticide and the environment. With these data and the laws of physics, chemistry, and biology, we can attack the problem of predicting what happens to a chemical in the environment. Our freedom to continue using pesticides depends on our ability to understand and predict their behavior in the environment. In this paper I will consider the bases of chemical behavior and the behavior of pesticides in plants."

Transport and transformation processes are key for determining how humans and other organisms are exposed to chemicals. These processes are largely controlled by the chemicals’ physical-chemical properties. This new edition of the Handbook of Physical-Chemical Properties and Environmental Fate for Organic Chemicals is a comprehensive series in four volumes that serves as a reference source for environmentally relevant physical-chemical property data of numerous groups of chemical substances. The handbook contains physical-chemical property data from peer-reviewed journals and other valuable sources on over 1200 chemicals of environmental concern. The handbook contains new data on the temperature dependence of selected physical-chemical properties, which allows scientists and engineers to perform better chemical assessments for climatic conditions outside the 20–25-degree range for which property values are generally reported. This second edition of the Handbook of Physical-Chemical Properties and Environmental Fate for Organic Chemicals is an essential reference for university libraries, regulatory agencies, consultants, and industry professionals, particularly those concerned with chemical synthesis, emissions, fate, persistence, long-range transport, bioaccumulation, exposure, and biological effects of chemicals in the environment. This resource is also available on CD-ROM

The fifth volume, Pesticides, completes this unique series of information-packed handbooks on environmental fate. The handbook contains fate calculations for a variety of pesticides of environmental interest today. No other volume offers current data in this convenient format.
