This review follows the PRISMA guidelines to provide a systematic of 115 peer reviewed articles that used non-targeted analysis (NTA) methods detect per- and polyfluoroalkylated substances (PFAS). literature highlights significant positive impact NTA in understanding PFAS environment. Within geographical bias exists, with most studies (∼60 %) conducted United States China. Future other regions (such as South America Africa) are needed gain more global understanding. More research is required marine environments atmosphere, current focus mainly on freshwater, groundwater, soil, sediments. The majority measuring environment, rather than commercial products (with exception AFFF). Non-lethal blood sampling has been successful for humans wildlife, but additional biomonitoring exposed cohorts understand health risks biotransformation pathways. mostly use liquid chromatography negative ionisation, which biases towards detection specific PFAS. Despite improvements data reporting quality assurance control (QA/QC) procedures, factors such false rates often overlooked, many workflows remain highly subjective. Perfluoroalkyl carboxylic acids (PFCAs) perfluoroalkyl sulfonic (PFSAs) detected classes, identified over 80 % studies, common routine monitoring. However, our >1000 from total 382 different 300 classes found fewer 5 studies. variety present limitations relying solely targeted methods. monitoring programs regulations would benefit considering comprehensive information

A Mini-Review of Full-Scale Drinking Water Treatment Plants for Per- and Polyfluoroalkyl Substances (PFAS) Removal: Possible Solutions and Future Directions

The United States Environmental Protection Agency (US EPA) recently finalized the enforceable maximum contaminant levels for some per- and polyfluoroalkyl substances (PFAS) in drinking water which intends to substantially decrease their level it. Conventional processes full-scale treatment plants (DWTPs) are usually inefficient PFAS removal from source (i.e., groundwater surface water). There is an increasing interest investigating/evaluating advanced technologies PFAS-contaminated help generate a number of potential solutions this engineering design challenge/problem. While numerous excellent research studies have been carried out reported literature on efficiency several removing water, mostly at lab- pilot-scales, DWTP investigations still need further attention. This study reviews US EPA’s quality guidelines/regulations, remediation DWTPs. Then, it discusses configurations water) as well suggesting future directions. Further effect environmental factors (e.g., organic matter) removal, effective elimination short-chain real using cost-effective industrially applicable technologies, efficiency/performance trains including innovative long-term produce associated costs, cost reduction/minimization via process optimization interest.
