This book provides a comprehensive, scientific, rigorous, and dispassionate overview of environmental pollutants. It presents the toxicological mechanisms and health effects of these contaminants, whether they have been around for a long time — such as lead, particulates, and persistent organic pollutants — or are more recent, such as certain pesticides, bisphenols, and other endocrine disruptors. It also offers an overview of the main risk management options under debate: prevent or cure, inform or ban, take precautionary measures.
