Description

Human exposure to chemicals is usually studied and understood in terms of the effect of a single pure chemical, but most humans are exposed to mixtures of chemicals. The project is focused on determining how human exposure to chemicals is influenced by these chemicals being part of a commercial mixture. Such mixtures could be cleaning products, pharmaceuticals, persona-care products, and commercial chemical mixtures.

Since different chemicals interact in a number of ways, the project is seeking a set of rules that allow regulators and managers to determine what sort of mixture they are working with and how to best assess the exposure risk associated with it. The project will assess the quality and effectiveness of several state-of-the-art tools for predicting the properties of chemicals in mixtures. Ultimately, it will develop a prototype software tool that will allow for the estimation of human exposure from mixture components via inhalation and skin absorption.
