Miljögifter i dricksvatten - ett dolt problem för många

Åtgärder mot PFOS och PFOA. Till riksdagens talman. En studie, finansierad av Nordiska ministerrådet, och som omfattade de fem nordiska länderna. av två viktiga perfluorerade ämnen: PFOA (perfluoroktansyra) och PFOS (perfluorooktansulfonsyra).

PFOA and PFOS are fluorinated organic chemicals that are part of a larger group of chemicals referred to as per- and poly-fluoroalkyl substances (PFASs). PFOS and PFOA have been extensively produced and studied in the United States. These manmade substances have been synthesized for water and lipid resistance. What Are PFOA and PFOs? PFO is perfluorooctane sulfonate and PFOA is perfluorooctanoic acid and both are part of a class of compounds called perfluoroalkyl substances (PFAS).

These manmade substances have been synthesized for water and lipid resistance. They have been used extensively in consumer products such as carpets, clothing, fabrics for furniture, paper packaging for food, and other materials (e.g., cookware) designed to be waterproof, stain-resistant or non-stick. Status Updates regarding the PFOA/PFOS Concentration Levels Updated 11/12/2020 PFOA/PFOS Water Advisory Lifted Effective 11/12/2020 the Georgia EPD has lifted the City of Summerville PFOA/PFOS health advisory for all City of Summerville water customers.

Testing for PFOS and PFOA in Drinking Water: The EPA has set the combined limit for PFOA and PFOS in drinking water at 70 parts per trillion. But this is only an advisory level and is not enforced. There is no national legal cap on the amount of PFOA and PFOS in drinking water.

Health Advisories. EPA has established health advisories for PFOA and PFOS based on the agency’s assessment of the latest peer-reviewed science to provide drinking water system operators, and state, tribal and local officials who have the primary responsibility for overseeing these systems, with information on the health risks of these chemicals, so they can take the appropriate actions to PFOS refers to Perfluorooctane Sulfonate and PFOA stands for Perfluorooctanoic Acid. They are water and stain-resistant synthetic compounds that are difficult to break down in the environment and in the human body.

Army Polyfluoroalkyl Substances (PFAS) · The Army Addresses PFOS/PFOA · Map: Sampling Results with PFOS/PFOA Exceedances at Army Installations. PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate) are the two most commonly produced PFAS worldwide (1).

Perfluorooctanoic acid (PFOA) has been a manufactured perfluorochemical and a byproduct in producing fluoropolymers. Perfluorochemicals (PFCs) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water.

Both are fluorinated organic chemicals, part of a larger family of compounds referred to as perfluoroalkyl substances (PFASs). These substances are synthetic compounds that are unique for being water and lipid-resistant. Perfluorooctanoic acid (PFOA), also known as C8, is another man-made chemical. It has been used in the process of making Teflon and similar chemicals (known as fluorotelomers), although it is burned off during the process and is not present in significant amounts in the final products. Perfluorooctanoic acid (PFOA) has been a manufactured perfluorochemical and a byproduct in producing fluoropolymers. Perfluorochemicals (PFCs) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. PFOA and PFOS are extremely persistent in the environment and resistant to typical environmental degradation processes.
