Effects of Perfluorinated and Polyfluoroalkyl Substances on Environmental Microbial Communities
Per-and polyfluoroalkyl substances(PFASs)have attracted significant attention as a emerging environ-mental contaminant.The biological toxicities and ecological health risks associated with PFASs have emerged as a popular subject for ecotoxicology related research.PFASs have a detrimental impact on individual microbes in the environment.Furthermore,prolonged exposure to PFASs can disrupt the composition,structure and enzyme activity of the microbial community in the environment,disrupting the normal cycling of materials and energy in the eco-system.This paper reviewed the impact of PFASs on microbial community structure and diversity across various environmental media,namely freshwater,marine and soil.Additionally,it summarizes the effects of enzyme activity and function in response to PFASs.Based on these findings,an assessment of the future direction of ecological risk assessment of PFASs was conducted to provide a theoretical basis and support for unbiased environmental and eco-logical risk assessment of PFASs.
