Per- and poly-fluoroalkyl substances (PFAS) are a new type of persistent organic pollutants that have received extensive attention in recent years. This article reviewed the population characteristics of environmental exposure to PFAS, as well as the potential health effects. Previous studies have verified that people are exposed to PFAS mainly through ingestion, and food and water are the dominant contributors. In terms of exposure characteristics, geographical, gender, age, and occupational differences have an impact on the level of PFAS exposure in the corresponding populations by influencing their behavioral characteristics and metabolic levels, with occupational exposure receiving more attention, especially in the exploration of novel PFAS. PFAS associate with a variety of adverse health effects caused by hepatorenal toxicity, immunotoxicity, reproductive toxicity, neurotoxicity, and carcinogenicity. However, some of the conclusions are not completely consistent, and the published epidemiological studies have focused on children and young people, lacking relevant data of the elderly. Future research can pay more attention to the elderly population and carry out validation exploration on controversial conclusions.
