Impact/Purpose:
Novel screening methods allow for wider range of personal care product chemicals to be measured
Description:
BACKGROUND AND AIM: The assessment of human exposure to chemical constituents of personal and household care products is an enormous challenge. It is hindered by the vast array of products, considerable variability in formulations, and ubiquitous use. The U.S. Environmental Protection Agency’s Office of Research and Development partnered with the National Institute of Environmental Health Sciences in a pilot study to evaluate effective exposure assessment strategies, with an emphasis on novel and non-traditional methods. METHODS: The consumer product use of nine female, nonsmoking participants was monitored over a 10-day period. Biological and environmental samples were collected, including silicone wristbands used as personal monitors. A suite of chemicals absorbed by the wristbands, including many commonly associated with consumer products, was measured via a contract with the Food Safety and Environmental Stewardship (FSES) program at Oregon State University (OSU). Wristbands were extracted using thermal and liquid extraction methods and a wide range of analytes were measured using GC/MS, including 1400 chemicals using OSU’s multiple analyte quantitative screening method. RESULTS: Only about 60 compounds out of more than 1400 were detected using the quantitative screening method. However, among the compounds with at least one detected measurement were phthalates, personal care product ingredients, and flame retardants, which were detected at frequencies of 52%, 41%, and 32%, respectively. CONCLUSIONS: Wristband samplers hold considerable promise as a personal and low-burden sampling method that identifies a broad swath of chemicals to which we are exposed. However, to realize this potential, careful consideration needs to be given to sampling duration. Despite far fewer compounds being detected using silicone wristband samplers over a ten-day period than expected, several compounds associated with personal care products were measured with relatively high detection frequencies. Moreover, as several of these compounds are not typically measured in exposure studies, these results are expected to inform future studies of exposure to chemical constituents of consumer products.
