It’s no secret that per- and polyfluorinated alkyl substances (PFAS), also known as forever chemicals, are now well-established in the human body, with their presence detected in blood, umbilical cords and human milk. And while experts have linked PFAS exposure to health concerns like elevated cancer risks, endocrine disruption, developmental disruption and reduced immune system […]
In a new study, researchers at University of Southern California (USC) have associated certain neighborhood factors — such as food access or proximity to Superfund sites — with higher levels of per- and polyfluoroalkyl substances (PFAS) in human blood. The researchers examined the levels of certain types of PFAS, including PFOS, PFOA, PFHxS, PFPeS and […]
In a new study, researchers have found a link between the use of certain personal care products, such as makeup, hair products and fragrances, by pregnant people and higher levels of per- and polyfluoroalkyl substances (PFAS) in human milk. Researchers compared the use of personal care products and PFAS levels in prenatal plasma and human […]
Right now across the U.S., drought persists, particularly in the northeast, where wildfires are burning because of the dry conditions. At the same time, some communities are still recovering from the catastrophic effects of hurricane season and the wind and water mash-up they wrought. In either case, water – both as a source of life […]
A new study has found per- and polyfluoroalkyl substances (PFAS) in Miami’s rainwater. It is the most recent evidence that “forever chemicals” get caught up in the water cycle and circulate over great distances. “PFAS are practically everywhere,” said Natalia Soares Quinete, author of the study and an assistant professor of chemistry at Florida International […]
Per- and polyfluoroalkyl substances, also known as PFAS or forever chemicals, have been found in groundwater, tap water, bottled water and food packaging. Now, officials in Maine are warning that these chemicals may be turning up in wild game in certain parts of the state, and that hunters should refrain from eating what they kill. […]
Roughly 71 to 95 million people living in the contiguous United States — more than one-fifth of the population — may be reliant on groundwater with detectable concentrations of per- and polyfluoroalkyl substances (PFAS) for their drinking water, according to a new study by the U.S Geological Survey (USGS). The research provides the first national […]
In a new study, scientists detected the presence of 10 target per- and polyfluoroalkyl substances (PFAS), including compounds such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), in samples of tap water from the UK and China as well as in bottled waters from 15 countries. The study, published in the journal ACS ES&T Water, […]
Although scientists have known there are per- and polyfluoroalkyl substances (PFAS) in the air, they also knew that many airborne PFAS were going undetected. Now, a new method can detect for gaseous fluorine to better measure the previously undetected airborne PFAS. PFAS are made up of organofluorine compounds that can release fluorine into the air, […]
