Harmful PFAS Chemicals are Pervasive in Building Materials.
Toxic “forever chemicals” per- and polyfluoroalkyl substances (PFAS) are “pervasive” in building materials, exposing workers and the public to the substances, a recent report has warned. The report
, published by the US-based Green Science Policy Institute, examines the use of PFAS, a collection of around 4,700 manmade chemicals that do not break down in the environment, in the building industry.
The report states that PFAS are added to "roofing materials, paints and coatings, sealants, caulks, adhesives, fabrics, glass, and more", providing functions such as "weatherproofing, corrosion prevention, and resistance to stains, grease, and water". PFAS can contaminate water, air, food, and indoor dust during the manufacturing, use, and disposal of building materials, the report found#Construction#BuildingMaterials#PFAS#Contamination
