ToxStrategies scientists Mandie Kramer, Stephanie Vivanco, Jennifer Bare, and Julie Panko assessed general population exposure to acrylonitrile via the ambient air utilizing EPA’s air toxics monitoring data and tools. This study used EPA’s air monitoring data from its Air Quality System (AQS) from the past 11 years, and modeled data from EPA’s 2020 AirToxScreen assessment. Overall key findings suggest that general population exposure to acrylonitrile from ambient air is low, and that EPA’s AQS data is well suited for evaluating general population exposures. These results benefit the public, who gain an understanding their potential exposure to acrylonitrile, the EPA, who can better inform their TSCA acrylonitrile risk evaluation, and other researchers who aim to utilize AQS for general population exposure assessments.
