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.
That specific chemical compound is called perfluorooctanoic acid, or PFOA. Here's what you need to know. Sure, we've all said, "Eh, everything causes cancer," but the risks of PFOA are not over ...
2016 The EPA "published a voluntary health advisory for PFOA and PFOS" which warned that "exposure to the chemicals at levels above 70 parts per trillion, total, could be dangerous." [71] 2016 The city of Lake Elmo, Minnesota, sued 3M a second time for polluting their drinking water with PFAS chemicals.
The EPA was created in 1970 to accept certain functions and responsibilities from other federal agencies and departments. Since its inception, the EPA has run environmental programs that address radioactive waste disposal sites, off-site monitoring around nuclear power plants, and keeps an eye on natural sources of radioactivity, such as radon.

Certain PFASs are no longer manufactured in the United States as a result of phase-outs including the PFOA Stewardship Program (2010–2015), in which eight major chemical manufacturers agreed to eliminate the use of PFOA and PFOA-related chemicals in their products and emissions from their facilities.
The EPA estimates thousands of PFAS are already in the U.S. environment and can be found in drinking water, soil, food, household items such as carpets and cookware, and more.
The U.S. Environmental Protection Agency (EPA) published a non-enforceable health advisory for PFOA in 2016. The agency's health advisory level for the combined concentrations of PFOA and PFOS is 70 parts per trillion (ppt). [22] [23] In June 2020 the State of New Jersey published a drinking water standard for PFOA, the first state to do so.
What Causes Good Greens To Go Bad. Unlike what the post suggests, leafy greens aren’t a major source of ethylene.But they are sensitive to produce that emits the gas. That’s why you should ...
