Microplastics and per- and polyfluoroalkyl substances (PFAS) both represent persistent environmental contaminants that have been associated with human health risks. Microcystins are naturally occurring cyanobacterial toxins that may be present in drinking water sources. Recent concerns have emerged regarding the ability of microplastics to adsorb various types of organic contaminants, including PFAS and microcystins. This study examined the adsorption of two long-chain and two short-chain PFAS by virgin microplastics, as well as two common microcystins by both virgin and weathered microplastics in freshwater. Results indicate adsorption to be driven by specific types of polymers and dominated by hydrophobic interactions. Weathering may decrease adsorption of microcystins by introducing hydrophilic oxygen-containing groups to microplastic surfaces. This is the first known study to determine if PFAS and microcystins may be concentrated by microplastics in freshwater when considering environmentally relevant concentrations while also addressing questions regarding weathered microplastics.
