Quick Answer:<\/strong> A big study from 2022, published in Environmental Science and Technology, said something pretty important: the world’s PFAS contamination has already gone past what they consider a “safe operating space.” PFAS, or per- and polyfluoroalkyl substances, are everywhere. We’re talking about them showing up in just about everything. The good news is, advanced water treatment, like reverse osmosis, really helps with these water quality problems. AMPAC USA builds commercial and industrial systems specifically for these tough water treatment needs, and they come with certified, documented performance you can trust.<\/p>\n

Technol. 2022, 56, 16, 11172\u201311179\\nPublication Date:August 2, 2022\\nhttps:\/\/doi.org\/10.1021\/acs.est.2c02765\\nCopyright \u00a9 2022 The Authors. Published by American Chemical Society\\n\\nABSTRACT: Scientists think that PFAS pollution in the environment is so widespread, it actually defines its own “planetary boundary,” and we’ve already crossed it. To test this, they looked at four specific perfluoroalkyl acids (PFAAs) \u2013 PFOS, PFOA, PFHxS, and PFNA \u2013 in different places around the world: rainwater, soil, and surface waters. Then, they compared these levels to recently suggested safety guidelines.\\n\\nHere’s what they found, just looking at those four PFAAs:\\n\\n<\/p>\n

    \\n<\/p>\n
  1. Rainwater often has way more PFOA and PFOS than the US Environmental Protection Agency (EPA) says is safe for drinking water. Plus, the total of all four PFAAs in rainwater frequently goes over Danish drinking water limits.<\/li>\n

    \\n<\/p>\n

  2. PFOS levels in rainwater are often higher than the Environmental Quality Standard for Inland European Union Surface Water.<\/li>\n

    \\n<\/p>\n

  3. Because of what’s in the air, soils globally are polluted with these substances and often exceed proposed Dutch guidelines.<\/li>\n

    \\n<\/ol>\n

    \\n\\nSo, it’s clear: the global spread of these four PFAAs through the atmosphere means we’ve exceeded the planetary boundary for chemical pollution. It’s especially hard to fix PFAA levels in atmospheric deposition because these chemicals stick around forever, constantly cycling through water, even on sea spray from the oceans. Since it’s so hard to reverse our exposure to PFAS and their effects, we absolutely need to quickly limit how we use and release them.\\nKEYWORDS: PFAS, planetary boundary, chemical pollution, environmental exposure\\n\\nThe post Outside the Safe Operating Space of a New Planetary Boundary for Per- and Polyfluoroalkyl Substances (PFAS) appeared first on Facts About Water.\\n\\nSource: Water Feed<\/p>\n","protected":false},"excerpt":{"rendered":"
