Toxicology

Toxicology

Toxicology is the study of the impacts of chemicals (as drugs, food additives and environmental contaminants) on both humans and the environment.   The Industrial Revolution of the mid-19th century released many naturally-occurring chemicals into the environment in unprecedented amounts and resulted in the production of thousands of new substances. Results from toxicity studies support drug, food and industrial chemical regulation, remediation, and production.  Although past practices focused on exposures of high doses to single chemicals practitioners of the science have recognized the importance of evaluating the impacts of low doses, and chemical mixtures as more sensitive biochemical and genomic methods are incorporated into chemical evaluation and regulation.
