A fundamental step in risk assessment is establishing what level of chemical contamination is safe. Toxicity reference values (TRVs) represent an exposure dose that people can safely be exposed to without adverse effects. Toxicity reference values are used to derive drinking water and soil quality guidelines, and to calculate hazard quotients (HQs) that determine risk […]
