Newly developed pesticides are present in surface waters, but how do we evaluate and understand their effects? Evidence of pesticide contamination of surface waters has spurred interest in aquatic pesticide exposure and its subsequent effects on humans and the environment. This book discusses monitoring, aquatic toxicology, risk assessment, modeling, mitigation, and regulatory efforts to minimize contaminants and protect environmental integrity. Researchers and students at universities, chemists and toxicologists at agrochemical companies and contract laboratories, and consultants involved with resource conservation and environmental risk mitigation will find this work helpful.
