Figure 1.

An overview of federal chemical evaluations and assessments in the United States. As indicated by the figure key, the agency abbreviation and full agency name are located in the upper left corner above each subsection. Within each subsection, arrows lead from the relevant legislation (if applicable) to the evaluation or assessment (light shaded box) and then further to the downstream purpose of each (dark shaded box). For EPA and FDA, there are additional levels of organization above each statute based on where the chemical is found. Outlined boxes at the bottom of each subsection indicate a formal regulation or standard that directly results from the evaluation or assessment; non-outlined boxes indicate non-binding guidelines or recommendations alone. Underlined text denotes active hyperlinks available for further reference in the interactive HTML version. A fully interactive version of this image is available as Supporting Information.
