EPA-Expo-Box (A Toolbox for Exposure Assessors)
The concentrations of chemicals from consumer products to which humans are exposed from the manufacture, distribution, use, or disposal of these products may be determined based on measurements or modeling. Characterizing contaminant concentrations for an exposure scenario is typically accomplished using some combination of the following approaches:
- Sampling consumer products and measuring contaminant concentrations
- Modeling the concentrations based on source strength, media transport, and chemical transformation processes
- Using existing, available measured concentration data collected for related analysis or compiled in databases
Tools that may be used to estimate exposure concentrations associated with consumer product use are provided in the table below.
