Description
Dermal exposure modeling is an important skill for OEHS professionals. Methods for dermal exposure assessment are an active area of research and development within the OEHS community. Dermal exposure modeling is useful as both a screening tool and a primary exposure assessment methodology for scenarios where: a) skin contact exposure is suspected but cannot be measured; or b) workers have complaints that need to be addressed. This introductory-level session will provide information on: 1) the theory of dermal exposure modeling; 2) the utility of exposure modeling for skin contact exposure in the workplace; 3) the strengths and weaknesses of dermal modeling as a tool; 4) resources such as the AIHA Mathematical Modeling textbook, AIHA Risk Assessment Tools page, and other governmental and consensus resources; 5) examples of screening-level models and detailed mass-balance models. A targeted, practical overview of model input parameter selection methods will be performed using the IH SkinPerm tool. Because there are no established consensus quantitative dermal exposure limits, a methodology for converting modeled dermal dose to an inhalation-equivalent dose will be provided. The session will conclude with a detailed case study, which will be used to demonstrate the utility of modeling for assessing the exposure of an SEG to two solvent chemicals with varying volatility.
