Environmental Toxicology

About this book

This book addresses the need for the exchange of scientific information among experts on issues related to environmental toxicology, toxicity assessment and hazardous waste management. Publishing papers from the First International Conference on Environmental Toxicology, the text will be of interest to biologists, environmental engineers, chemists, environmental scientists, microbiologists, medical doctors and all academics, professionals, policy makers and practitioners involved in the wide range of disciplines associated with environmental toxicology and hazardous waste management.

The text encompasses themes such as: Acute and Chronic Bioassays; Tests for Endocrine Disruptors and DNA Damage; Interactive Effects of Chemicals; Bioaccumulation of Chemicals; Assessment of Ecotoxicological Properties of Hazardous Wastes; Hazardous Waste Management Techniques; Legislation Regarding Environmental Effects of Chemicals; Hazardous Waste Reduction and Recycling Techniques; Biodegradation and Bioremediation; Monitoring of Hazardous Waste Environmental Effects; Laboratory Techniques and Field Validation; Effluent Toxicity, Microbiotests; On-line Toxicity Monitoring; Forensic Toxicology; Genotoxicity/Mutagenicity; Exposure Pathways; Risk Assessment; Biotesting and Environmental Control Strategy; Hot Spots and Accidental Spills.
