Preface of Environmental Fate and Effects of Pesticides

The primary purpose of this book is to provide an update on research in the field of environmental impact of agricultural chemicals. As society becomes more concerned with non-target effects of pesticides and their residues in the environment, it is imperative that researchers develop a deeper and broader understanding of the types of effects, the quantities of the compounds that are biologically available, and the probability of serious impacts. Risk assessment can utilize information about the effects and the quantities to develop assessments of the likelihood for a given chemical, used in a specific place and time, to have deleterious effects on various species or ecological associations in the ecosystem

Preface of Veterinary Pharmaceuticals in the Environment

An important symposium was presented on Veterinary Pharmaceuticals in the Environment at the 233rd National Meeting of the American Chemical Society on March 25-26, 2007, in Chicago, IL. The excellence and timeliness of the presentations indicated the need for an ACS Symposium Series book addressing the environmental chemistry and toxicology of this group of emerging contaminants. The purpose of this symposium was to bring together scientists from academia, government, and industry to discuss and present data relevant to the significance of veterinary pharmaceuticals in the environment. A broad range of topics was covered, including environmental chemistry studies focusing on transport, mobility, sorption, persistence, and bioavailability of the compounds, as well as development of analytical techniques relevant to detection of the pharmaceuticals in environmental matrices, discussion of ecotoxicological studies of veterinary pharmaceuticals, and information relevant to ecological risk assessments. The primary classes of drugs addressed herein are veterinary antibiotics and syntheti
