Impact/Purpose:
Data is currently limited for which chemicals humans are a exposed to and in what quantities these chemicals are present for exposure.High-throughput exposure models have been developed to aid in exposure estimates, however these models require information on chemical composition in product formulations and articles in indoor environments. This work describes how suspect screening can aid in filling in data for these models.
Description:
This presentation details a pilot suspect screening analysis (SSA) of common consumer products done under the Rapid Exposure and Dosimetry project of CSS. This work presents methods which can rapidly characterize chemicals identified in consumer products including formulations (shampoos, lotions) , articles (carpets, upholsteries), and foods (cereals). Models predicting a chemicals's functional use in products are applied to bolster chemical identifications, and reported concentration data from public product information is used to gauge the accuracy of the chemical concentrations estimated in the SSA.
