Exposure Assessment Tools by Chemical Classes


Exposure assessment is one of the four major steps in risk assessment. Others include hazard identification, dose-response assessment, and risk characterization.

Exposure may be estimated for chemicals in any of a variety of chemical classes: pesticides, other organics, inorganics and fibers, or nanomaterials. Alternatively, exposure assessments may be categorized according to exposure assessment approaches, exposure media, exposure routes, assessment tiers or types, or lifestages and populations.
