The term "per- and polyfluoroalkyl substances" (PFASs) refers to a big class of thousands of synthetic chemicals used in daily life. They are, however, being identified more frequently as environmental pollutants, and some of them have been linked to harmful impacts on both human health and the environment The carbon-fluorine interactions are among the strongest in organic chemistry and are therefore resistant to deterioration both during use and in the atmosphere. The majority of PFASs can be readily transported through the environment over great distances from their source of release. Groundwater, surface water, and sediment contamination by PFASs have frequently been seen. It is physically challenging and expensive to clean up polluted sites. They can build up in the atmosphere, water and food.

On January 13, 2023, the plan was submitted to ECHA after being prepared by authorities in Denmark, Germany, the Netherlands, Norway, and Sweden. In addition to making processes and products safer for people, it seeks to reduce PFAS emissions into the environment. All PFASs covered by the plan have a high level of environmental persistence. People, plants, and animals will become more exposed if their releases are not limited. Unrestricted levels will cause negative impact on people's health and the environment. According to the authorities, if nothing is done, 4.4 million tonnes of PFASs will enter the ecosystem over the next 30 years.

By March 2023, Risk Assessment (RAC) and for Socio-Economic Analysis (SEAC) will validate if the submitted the proposal meets the legal requirements of REACH failing which the scientific community will re-evaluate the proposal. While RAC will examine if the restriction is appropriate while SEAC will examine on the cost-benefit analysis associated with the proposal. The committee will also consider advice from Enforcement forum on the proposed PFAs restriction.
