Research Progress of Concentrations and Exposure Assessment of Perfluorinated Alkyl Substances in Main Food in China

Perfluorinated alkyl substances (PFASs) is a new kind of persistent organic pollutants (POPs) that does great harm to human health. In recent years, as PFASs being widely used in various fields, it has been widely detected in various media worldwide. The study of the contamination level of PFASs in food has become an important topic of national and public concern. In this paper, the progress of domestic research on the contamination level of PFASs in food in recent years is reviewed.The pollution levels of PFASs in domestic main animal food (eggs, aquatic products, meat and dairy products) and drinking water were analyzed.The contamination characteristics of PFASs in different foods are compared. A hazard index was used to assess the health risks of exposure to PFASs through staple foods in Chinese populations.
