The US-based Interstate Technology and Regulatory Council (ITRC) has undertaken an extensive evaluation of ex-situ and in-situ treatment technologies for PFAS-impacted liquid matrices. These technologies are divided into field-implemented technologies, limited application technologies, and developing technologies and typically fit into one of ...
PFA is commonly used as a material for piping and as fittings for aggressive chemicals, as well as the corrosion-resistant lining of vessels in the chemical-processing industry. Typical applications include the construction of gas scrubbers, reactors, containment vessels and piping. [ 6 ]
April 2001 In a highly cited article in the Environmental Science & Technology, published by the American Chemical Society, John Giesy and Kurunthachalam Kannan reported "for the first time, on the global distribution of perfluorooctanesulfonate (PFOS), a fluorinated organic contaminant." Based on the findings of their 2000 study, Giesy and ...
Performic acid (PFA) is an organic compound with the formula CH 2 O 3. It is an unstable colorless liquid which can be produced by mixing formic acid with hydrogen peroxide . Owing to its oxidizing and disinfecting action, it is used in the chemical, medical and food industries.
PVDF is widely considered safe and ubiquitous used for water treatment, [24] the food industry, and biocompatible devices like hernia meshes or internal devices. PVDF differs from PFAS in that alternating groups are hydrogen, making it less resilient to high temperatures, but also meaning that byproducts don't degrade into known hazardous PFAS ...
Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness.The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak.

A new rule from the Food and Drug Administration (FDA) will update what it means for food to be labeled “healthy” for the first time in 30 years, a move that aligns with current nutrition ...
Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8-carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.
