Toxic injury to the skin in the general population, and particularly in western populations, is on the increase. This is partly due to the expanding number of natural and man-made chemicals present in our everyday environment. The need for a thorough understanding of the skin, and the mechanisms of toxicity therein, has never been more pressing. Th

Ecotoxicology is the evaluation of toxic effects within the environment, typically within one specific ecosystem, like a forest, stream, or lake. For years now, ecotoxicological studies have tended to focus on one toxicant at a time. But that isn't how an ecosystem encounters toxicants (or stresses): there may be several elements at work in the air, several more in the water, and still more already within the soil of any given ecosystem, and all have some level of toxic influence on that ecosystem. Multiple Stresses in Ecosystems presents the state-of-the-art in determining the effects of these multiple impacts upon ecosystems. Resulting from a vanguard conference originally held in 1993 at UC Davis, this new work is divided into three sections that present methodolgies for assessing the health of an ecosystem; the effects of multiple toxicological impacts upon an ecosystem, and which tools are worth using to assess these dangers. Environmental scientists, chemists, toxicologists, risk analysts, and probably the entire membership of SETAC will find need for this book, as will wetlands scientists, ecologists, and research biologists.

This book is a summary of the presentations and discussions at the Workshop on Methods of Pesticide Exposure Assessment held in Ottawa, Canada, on October 5-8, 1993. The event was a joint effort of Health Canada and the North Atlantic Treaty Organisation and was officially supported by the United States Environmental Agency and the Organisation for Economic Co-operation and Development (OECD). The goal of the workshop was to examine current issues in the field of pesticide exposure assessment with the aim of reaching an internationally harmonized approach to methods of exposure assessment. With regulatory agencies of OECD Member countries moving towards the harmonization of data requirements...
This book is a tutorial designed to instruct the reader in use and application of immunochemical methods of analysis for environmental contaminants. A brief introduction describes basic principles and the advantages and disadvantages of the technology, and gives a listing of references which supply more detail. Preparation of the laboratory for use of this technology and the general scientific considerations prior to using the technology are discussed. Detailed step-wise procedures are given for analysis of selected analytes, triazine herbicides, carbaryl, paraquat, and p-nitrophenols, etc. In addition to the specific immunoassay methods, a series of support techniques necessary to perform i...

Fate of Pesticides in Large Animals covers the proceedings of the 1976 Fate of Pesticides in Large Animals symposium. The symposium is held at the Centennial Meeting of American Chemical Society and sponsored by the Pesticide Chemistry Division of the ACS. It aims to focus on the fate of pesticides in large animals and to assemble a thesis on the subject covering its theoretical and practical significance. In this book, large animals are particularly considered, because they often metabolize chemicals differently than small laboratory rodents. These differences may prove a basis for the development of concepts pertinent to the phenomenon of selective toxicity. This book is divided into three...
