Abstract A primary route of occupational exposure to toxic chemicals is often through the skin. Exposure to complex mixtures of chemicals is the norm in most of these settings. Although the mechanism of absorption of a single chemical has been well studied, effects of co-administered chemicals on absorption of a systemic toxicant may ultimately determine whether this potential toxicity is ever realized. Estimating exposure for risk assessment purposes under this scenario is difficult, as available databases are based on single chemical exposure. Our group has previously studied the nature of chemical interactions within a mixture that could modulate absorption across the skin. The objective of this present grant was to extend the analysis of chemical mixture interactions that affect percutaneous absorption to define the physical chemical characteristics of the mixture that allow significant mixture interactions to be detected.
