Dermal Exposure Assessment: A Summary of EPA Approaches
EPA is announcing the completion of the final report, Dermal Exposure Assessment: A Summary of EPA Approaches and its availability to the public.
This final report presents a concise description and evaluation of the approaches used in the Agency for dermal exposure assessment including a discussion about harmonization and research needs in this area. The report is intended to be used by EPA program offices in their efforts to refine and revise the methods they use to assess dermal exposure to chemicals in the environment and to facilitate cooperation in the development of new methods, models and guidance for dermal exposure assessment.
This report was then used as the basis for the dialogue at a RAF sponsored cross-Agency colloquium, the Colloquium on Dermal Exposure Methods Comparison in 2005, to identify common factors and differences of dermal exposure assessment methods, to identify opportunities for harmonization among different dermal exposure assessment methods, and to determine future research needs (U.S. EPA, 2005). Coincidentally, the RAF report and colloquium coincided with NCEA research efforts to evaluate methods to estimate permeability coefficients (Kp) and to assess the importance of dermal exposure to chemically contaminated water, soil, and sediment, leading to the development of this report.
