The effects of climate change on human health are profound because they increase heat-related illnesses and deaths, respiratory diseases, and the spread of infectious diseases. There is widespread agreement among researchers, health professionals and organizations that climate change is the biggest global health threat of the 21st century. [1] [2]
10 January 2018 According to the U.S. Department of Health & Human Services's Agency for Toxic Substances and Disease Registry (ATSDR) website, which was last reviewed on10 January 2018, the "health effects of PFOS, PFOA, PFHxS, and PFNA have been more widely studied than other per- and polyfluoroalkyl substances (PFAS). Some, but not all ...
On May 19, 2016, EPA lowered the drinking water health advisory level to 0.07 ppb for PFOA and PFOS. [173] In June 2022 the agency issued updated advisories, stating that "some negative health effects may occur with concentrations of PFOA or PFOS in water that are near zero and below EPA's ability to detect at this time."
A number of jurisdictions have guidelines or limits for the concentration of PFHxS in water, in diets, and in the environment. There are fewer regulations on PFHxS compared to PFOS and PFOA. This reflects the relative lack of epidemiological and toxicological information on the human health effects of exposure to PFHxS. [4]
The Devil We Know is a 2018 investigative documentary film by director Stephanie Soechtig regarding allegations of health hazards from perfluorooctanoic acid (PFOA, also known as C8), a key ingredient used in manufacturing Teflon, and DuPont's potential responsibility.
Examples include PFOA and PFOS, frequently present in water-resistant textiles and sprays conferring water-resistant properties to textiles and fire-fighting foam. [3] Data from animal studies of PFOA indicate that it can cause several types of tumors and neonatal death and may have toxic effects on the immune, liver, and endocrine systems.
There is a growing body of research investigating the health effects of PFOS in humans and animals, including the reproductive, developmental, liver, kidney, thyroid, and immunological effects. [42] According to a 2002 report by the Environmental Directorate of the OECD, "PFOS is persistent, bioaccumulative, and toxic to mammalian species." [43]
