Abstract
Per- and polyfluoroalkyl substances (PFAS) are unseen, dangerous organic compounds that can cause major health disorders. PFASs have been categorized as persistent, bioaccumulative, and toxic (PBT). This review provides knowledge about the PFASs present in junk food packaging materials, which can migrate into the food. Different types of samples were analyzed using the analytical methods. The most preferred method of extraction is ultrasonic-assisted extraction (UAE). It summarizes the analytical approaches of PFASs. The results of numerous studies show that perfluorooctanoic acid is the most often detected compound with high concentrations. The European Food Safety Authority (EFSA) announced that the tolerable weekly intake (TWI) of PFASs is 4.4 ng/kg. The US Environmental Protection Agency (EPA) has announced the limit for perfluorobutane sulfonic acid due to its toxicity level. These compounds have potential effects on both people's health and the biosphere. PFAS usage has to stop in the industries for a better future.
