Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are anthropogenic chemicals widely used in industrial applications. PFASs are ubiquitous in the environment, and many are toxic and bioaccumulative. PFASs in the environment still comprise many compounds which either have not yet been monitored/studied or are not well characterized (unknown PFASs). These unknown PFASs, with uncertain toxicities, may be intentionally manufactured as alternatives for legacy PFASs or unintentionally produced as byproducts. Waters of the Pearl River Estuary and the South China Sea are important sinks of PFASs, the distribution of which is strongly influenced by ocean currents. To study the occurrence of legacy, new, and unknown PFASs from land-based sources to coastal waters in the PRE, we propose analyzing legacy, new, and unknown PFASs in seawater, samples collected in coastal waters of Hong Kong to evaluate the spatial distribution and seasonal variations of the PFASs.
