Risk Assessment

Environmental regulatory agencies apply traditional risk assessment processes to estimate an amount of chemical in the environment that could cause an adverse health outcome to humans and ecological receptors.  The estimated chemical concentration is derived from scientific studies of the chemical’s toxicity combined with upper range values of exposure that a person, plant, or animal may experience.
