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.

Exposure Assessment

Exposure assessment is "the process of estimating or measuring the magnitude, frequency, and duration of exposure to an agent, along with the number and characteristics of the population exposed. Ideally, it describes the sources, routes, pathways, and uncertainty in the assessment."
