  "abstract": "Per- and polyfluoroalkyl substances (PFAS) are persistent anthropogenic contaminants widely 20 detected in aquatic environments. Conventional wastewater treatment plants (WWTPs) are major 21 emission sources that discharge PFAS via effluent and the land application of biosolids, yet they 22 are ineffective in removing PFAS. Understanding PFAS distribution and transformation in 23 WWTPs is important for the development and integration of PFAS remediation technologies. 24 However, identifying the mechanisms governing each PFAS mass flow change across a treatment 25 compartment remains challenging, and parameters quantifying PFAS transformation and 26 distribution in the field are difficult to measure. To address these problems, we developed novel 27 mass balance-based computational frameworks for PFAS distribution and transformation in 28 WWTP. We demonstrated that they are robust tools for identifying the mechanisms driving 29 changes in PFAS mass flow and for estimating unobservable parameters describing PFAS 30 distribution and transformation. Also, based on these frameworks, we found that the impacts of 31 PFAS partitioning on PFAS concentrations in the aqueous phase were two to three orders of 32 magnitude higher than those of precursor transformation. These frameworks are extensible, and 33 remaining limitations in parameter uncertainty and transformation pathway completeness are 34 discussed. 35 36",
