This book brings together key features of the toxicology of pesticides and the way their use is regulated in the main trading regions of the world. There are chapters on each of the main groups of insecticides, namely organochlorines, anticholinesterases and pyrethrins and pyrethroids. The book also covers fungicides and herbicides, as well as more specialised agents such as microbial pesticides. Occupational risks to humans are considered, and aspects of pesticide poisoning through the consumption of contaminated foodstuffs, are discussed. The possibility of harm from pesticide exposure has led to the development of national and international regulations governing the application of pesticides. The book describes the regulatory systems in three major economic areas: the North American Free Trade Area (USA, Canada and Mexico), the European Union and Japan. This book should be of interest to all researchers working on the development and application of pesticides anywhere in the world. All those involved in the regulation of pesticides should also benefit from reading this book.
