Polyfluoroalkyl substances, or PFAS, are a group of man-made chemicals that includes perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), perfluorononanoic acid (PFNA), perfluorohexane sulfonic acid (PFHxS) and many others. PFAS have been manufactured and used in a variety of industries around the world since the 1940s. Certain PFAS such as PFOA and PFOS, PFNA and PFHxS, don’t break down in the environment or in the human body, and can accumulate over time. Exposure to PFAS may lead to adverse health effects. People can be exposed to PFAS in different ways, for example through food. Food can become contaminated through contaminated soil and water used to grow the food, through the concentration of these substances in animals via feed and water, through food packaging containing PFAS, or equipment that contained PFAS during food processing.
In 2019, ECHA increased the number of checks carried out on companies’ chemical safety data by 50 %. Important safety data has been requested to clarify long-term effects of chemicals on human health and the environment, including those affecting reproduction and causing genetic mutations.
