The purpose of this project is develop models for estimating dermal absorption of contaminants from sediments/soils.

Project Status

This project began in November 2002. To date SPME lab protocols have been developed and tested on several chemicals.

Project Completion Date (Actual/Projected)



The mechanisms by which contaminants are released from sediments/soils and absorbed into the skin are poorly understood. The project will first conduct invitro experiments to study the effects of particle layering and chemical saturation. Secondly, mechanistic models will be developed to estimate dermal absorption into the skin. The final Co-op report was recieved in May 2007.
