Book Description
Understand the fundamentals of human risk assessment with this introduction and reference Human risk assessments are a precondition for virtually all industrial action or environmental regulation, all the more essential in a world where chemical and environmental hazards are becoming more abundant. These documents catalog potential environmental, toxicological, ecological, or other harms resulting from a particular hazard, from chemical spills to construction projects to dangerous workplaces. They turn on a number of variables, of which the most significant is the degree of human exposure to the hazardous agent or process. Human and Ecological Risk Assessment combines the virtues of a textbook and reference work to introduce and analyze these vital documents. Beginning with the foundational theory of human health risk assessment, it then supplies case studies and detailed analysis illustrating the practice of producing risk assessment documents. Fully updated and authored by leading authorities in the field, the result is an indispensable work. Readers of the second edition of Human and Ecological Risk Assessment will also find: Over 40 entirely new case studies reflecting the latest in risk assessment practice Detailed discussion of hazards including air emissions, contaminated food and soil, hazardous waste sites, and many more Case studies from multiple countries to reflect diverse international standards Human and Ecological Risk Assessment is ideal for professionals and advanced graduate students in toxicology, industrial hygiene, occupational medicine, environmental science, and all related subjects.

Book Description
This edited book, Toxicity and Hazard of Agrochemicals, is intended to provide an overview of toxicology that examines the hazardous effects of common agrochemicals employed every day in our agricultural practices. Furthermore, it is hoped that the information in the present book will be of value to those directly engaged in the handling and use of agrochemicals and that this book will continue to meet the expectations and needs of all interested in the different aspects of human and environmental risk toxicities.

Book Description
The nicotinoids are the most important new class of pesticides, joining the organophosphorus compounds, methylcarbamates, and pyrethroids as the major insecticides. Recently, imidacloprid and related nicotinoids have begun replacing organophosphorus and methylcarbamate compounds as insecticides to control insect pests on major crops. Nicotinoids act on the nicotinic acetylcholine receptor, as does naturally occurring nicotine, but with remarkable effectiveness against insects while being safe for mammals; they are quickly degraded and do not persist in the environment. This volume describes the relationship of nicotinoids to botanical insecticidal alkaloids, their discovery and development as insecticides, and the prospects for their expanded use and for the development of resistance. This book is the first to provide concise, comprehensive information on nicotinoids, their chemistry, mode of action, metabolism, and application in agriculture.
