RFA 21-1 Quantifying Real-World Impacts of Non-Tailpipe Particulate Matter Emissions

This RFA solicits applications to develop, evaluate, and apply real-world exposure indicators of non-tailpipe PM emissions from motor vehicles (e.g., from tire, brake, wheel weights, and road wear and resuspension of dust from the road surface) and to assess the impacts of such emissions on air quality, human exposure, and human health. The approaches of interest include:

1. Identifying and validating exposure indicators to characterize non-tailpipe PM emissions in near-road or ambient air.
2. Developing or extending existing approaches to measure or non-tailpipe PM in the near-road environment.
3. Estimating current and future potential impacts of non-tailpipe emissions from passenger and/or commercial vehicles on air quality, exposure, and/or potential contribution of non-tailpipe emissions to health burden attributable to ambient PM_2.5 mass.
