Cumulative exposure is defined as the exposure to multiple chemicals from multiple pathways acting through a common mechanism of toxicity. The first step in performing a cumulative risk assessment is to identify a common mechanism group. This involves identifying pesticides that share a common mode of action. Once a group of pesticides with a common […]
Aggregate Risk Characterization
Aggregate risk assessments allow for the evaluation of potential adverse health effects that could occur as a result of exposure to a single chemical from all routes (oral, dermal, inhalation) and sources (dietary, water, residential) of exposure combined. Any appropriate benchmark of toxicity (Point of Departure) selected by the risk assessor such as the no […]
