In 2024, a worldwide study of 45,000 groundwater samples found that 31% of samples contained levels of PFAS that were harmful to human health; these samples were taken from areas not near any obvious source of contamination. [62] Soil is also contaminated and the chemicals have been found in remote areas such as Antarctica. [63]
Some, but not all, studies in humans with PFAS exposure have shown that certain PFAS may affect growth, learning, and behavior of infants and older children, lower a woman's chance of getting pregnant, interfere with the body's natural hormones, increase cholesterol levels, affect the immune system, and increase the risk of cancer."
Even at very low levels, they have been linked to a range of health conditions, including thyroid problems, infertility and some cancers. People are exposed to PFAS in many ways, but drinking ...
PFAS then accumulates the biomass in fish, wildlife, ecosystems and humans. Two of the primary compounds of concern, PFOA and PFOS, pose a host of potential risks, particularly to children and ...
PFAS, which are human-made, are found in most municipal water supplies. ... While noting that research and regulatory levels for PFAS continues to evolve, “PFAS concentrations observed are not ...
Nearly 7 percent of Americans may be exposed to hazardous levels of “forever chemicals” through treated municipal wastewater, a new study has found. These approximately 23 million people may ...
Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is a chemical compound having an eight-carbon fluorocarbon chain and a sulfonic acid functional group, and thus it is a perfluorosulfonic acid and a perfluoroalkyl substance (PFAS).
According to the New York Times, forever chemicals can take up to 15 years to reduce by half in the human body, ... funding was approved to combat PFAS levels in water sources earlier this year.
