Humans are exposed to a multitude of chemicals, (1) typically in mixtures. Testing substances individually using traditional methods can be time consuming and cost prohibitive; (2) the number of possible chemical combinations makes this type of testing unrealistic for mixtures. (3) To circumvent these challenges, scientists at the U.S. Environmental Protection Agency (EPA) used a data-driven approach to identify and prioritize relevant chemical combinations, as reported recently in Environmental Health Perspectives. (3)

Other efforts to identify high-priority co-exposures have not captured the full spectrum of chemical combinations because of either the lack of ingredient information or insufficient purchase and use data. (2,4,5) "This study is unique because of the way we were able to integrate multiple data sets to improve our overall understanding of human exposure," says Zachary Stanfield, a postdoctoral researcher at the U.S. EPA and first author of the study.

Stanfield and colleagues matched consumer purchasing data from a marketing database compiled in 2012 with ingredient data obtained from the U.S. EPA's Chemical and Product Database. (6) The combined data streams included approximately 2.4 million purchases by about 53,000 households...
