Safeguarding economic prosperity, whilst protecting human health and the environment, is at the forefront of scientific and public interest. This book provides a practical and balanced view on toxicology, control, risk assessment and risk management, addressing the interplay between science and public health policy. This fully revised and updated new edition provides a detailed analysis on chemical and by-product exposure, how they enter the body and the suitability of imposed safety limits. New chapters on dose, with particular emphasis on children and vulnerable subpopulations, reproductive and developmental toxicants and toxicity testing are included. With updated and comprehensive coverage of international developments of risk management and safety, this will have broad appeal to researchers and professionals involved in chemical safety and regulation as well as the general reader interested in environmental pollution and public health.
