Impact/Purpose:
Presentation at the International Society of Exposure Science (ISES) Virtual Conference September 2021. This presentation describes a talk developed for an invited ISES session titled "Consumer Product Use in Under-Represented Communities"
Description:
Consumer products that are used in and around the home are a dominant source for anthropogenic chemical exposure. Prediction of the population distribution of chemical exposures encountered due to the residential use of consumer products (such as personal care products, cleaning products, pesticides, and pet products) require information about the corresponding distribution of consumer product use as well as information about the ingredients in those products. Here we aim to explore potential demographic disparities in exposure emerging from consumer product use. For a population of sixty thousand households, we merged product purchasing data with a database of chemical ingredient information collected from Safety Data Sheets and ingredient lists. We explored purchasing patterns (habits and practices) and resulting chemical introduction into homes in terms of demographic groups based on race/ethnicity, income, and education. We specifically examined demographic differences in purchases and associated chemical content of key product types, including household cleaners and disinfectants, residential pesticides, hair-care products, and cosmetics. We further considered the impact of brand type choice (e.g., store, mass market, or specialty brand) on the introduction of chemicals into households. Lastly, using data-mining methods, we investigated demographically stratified co-occurrence patterns in product purchases and in resulting potential chemical exposures. We demonstrated the impact of these demographic factors and purchasing choices via application to a case study group of potential endocrine active chemicals (EACs) as identified by consensus in vitro-based models of estrogen and androgen activity. In general, across all products and by product type, our results indicated that households with children, households headed by women of color, and lower income households exhibited divergence from the general population in the chemicals and chemical combinations they encounter most frequently. In addition, brand type choice in select product categories (including cleaning products and cosmetics) varied over demographics and contributed to patterns of EACs introduced to homes. These results indicate that consumer habits and practices potentially contribute to exposure disparities observed in biomonitoring studies.
