![]() These limits are used as signal values that help to minimise the risk of adverse effects due to the exposure of humans and the environment to PFAS. Risk limits indicate the quantity of a substance for which the risks are acceptable. For example, risk limits for water, soil, dredging spoil and air are derived. What does RIVM do?īased on the available scientific knowledge, RIVM derives risk limits for different types of PFAS. It can also be released into the environment through the use of PFAS-containing products, such as fire-fighting foams, textile impregnation agents, lubricants, or PFAS-containing products, which can be disposed of as waste. The substances are released into the environment through emissions from factories that make or use the substances. They are also used in various industrial applications and processes. They are found in various products, including lubricants, food packaging materials, extinguishing foam, non-stick coatings on pans, clothing, textiles and cosmetics. PFAS have useful properties: they are water, grease and dirt repellent. There is also a lack of clarity in science as to which substances exactly are PFAS and which are not. The OECD Organisation for Economic Co-operation and Development has identified more than 4,000 PFAS, but there may be more. The exact number of different PFAS produced by humans is not known. Well-known examples of PFAS are PFOA perfluoro octanoic acid, PFOS perfluorooctane sulfonates (perfluorooctane sulfonic acid) and GenX substances. PFAS can have a negative effect on the environment and health. This group of chemical substances is man-made and does not occur naturally in the environment. ![]() PFAS is a collective name and stands for per- and polyfluoroalkyl substances.
