Exposure assessment is part of the environmental science that focuses on measuring or estimating the exposure levels of a population or a subset of a population to chemical substances or contaminants.
Exposure analysis typically includes calculating the amount, frequency and duration of the exposure of the population to a chemical or to multiple chemicals using information on the levels of the chemicals in products or consumer goods or in the environment in which the population exists.
A realistic exposure assessment is based on real input data and uses scientifically validated models. Assessments will ideally include all the sources and routes of exposure (i.e. inhalation, digestion or dermal absorption). An effective exposure assessment should treat the uncertainty and variability factors in the assessment thus producing results with confidence intervals (i.e. 10mg/day +/- 1.2mg/day). This is also known as probabilistic exposure assessment. CREMe specialises in generating these results for our clients.
