<span style="font-family:"Noto Sans",sans-serif;color:#595959">Time activity patterns (TAPs) are widely used by environmental researchers and health professionals to estimate human exposure to, and health effects associated with, toxic substances (e.g., fluorinated
chemicals, plasticizers, flame retardants, heavy metals). For example, estimates of PFAS exposures are impacted by time spent in different indoor locations, products used, and the frequency of cleaning. TAP data are traditionally collected through observational
studies or activity pattern surveys, and the EPA’s Exposure Factors Handbook synthesizes these data to present values for the general U.S. population. However, the costs and effort associated with these studies mean that data for specific communities or demographics
may be unavailable or incomplete. Individual behaviors, household habits, and community characteristics can vary, which presents important considerations for quantifying human exposure to chemicals. Additionally, data from these studies may become outdated
as time-activity patterns shift due to economic and social changes, including the SARS CoV-2 epidemic. As a result, there exists an incredible potential for artificial intelligence (e.g., machine learning [ML]) to advance our understanding of TAPs that mediate
chemical exposures, by tapping into a variety of “big data” sources. The goal of this project is to develop data mining and ML-based approaches to collect and analyze publicly available big data including social media mentions and geotags, search engine trends,
and consumer product purchase data. Using supervised and unsupervised ML techniques such as natural language processing and pattern recognition, we will identify meaningful geographic, demographic, and temporal trends in TAPs that inform how and when individuals
are exposed to contaminants of concern.<o:p></o:p></span></p>
