Red List building materials. The Living Building Challenge (LBC) Red List contains chemicals commonly used in building materials that have been designated as harmful to "health and the environment". The International Living Future Institute (ILFI) created the list in 2006, and is the only organization that uses the term 'Red List'.
Per- and polyfluoroalkyl substances (PFAS[1] or PFASs[2]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [3] PFAS came into use after the invention of Teflon in 1938 to make fluoropolymer coatings and products that ...
Infobox references. Perfluorohexanesulfonic acid (PFHxS) (conjugate base perfluorohexanesulfonate) is a synthetic chemical compound. It is one of many compounds collectively known as per- and polyfluoroalkyl substances (PFASs). It is an anionic fluorosurfactant and a persistent organic pollutant with bioaccumulative properties.
Per-and polyfluoroalkyl substances are found in thousands of products most Americans use or come into contact with daily, such as: Food containers that have PFAs are waterproof and grease-proof ...
Their use became so widespread that a recent study by the U.S. Geological Survey found that 45% of America’s tap water is contaminated by at least one type of PFAS.
New Mexico began addressing PFAS chemicals when they were discovered in high concentrations surrounding Cannon and Holloman Air Force Bases, most likely from the use of Aqueous Film Forming Foam ...
This is a list of building materials. Many types of building materials are used in the construction industry to create buildings and structures . These categories of materials and products are used by architects and construction project managers to specify the materials and methods used for building projects .
The EPA also is pursuing a broader rule change to strengthen state and federal agencies' oversight of facilities that treat, store or dispose of hazardous waste, including materials that contain PFAS.
