PFAS River Export Analysis Highlights the Urgent Need for Catchment-Scale Mass Loading Data (2024)
Journal Article
Byrne, P., Mayes, W. M., James, A. L., Comber, S., Biles, E., Riley, A., & Runkel, R. L. (in press). PFAS River Export Analysis Highlights the Urgent Need for Catchment-Scale Mass Loading Data. Environmental Science and Technology Letters, https://doi.org/10.1021/acs.estlett.4c00017

Source apportionment of per-and polyfluoroalkyl substances (PFAS) requires an understanding of the mass loading of these compounds in river basins. However, there is a lack of temporally variable and catchment-scale mass loading data, meaning ident...
