Fighting 'forever chemicals' with microbes

Per- and polyfluoroalkyl substances (PFAS) are some of the most persistent environmental pollutants, earning them the moniker "forever chemicals." Increasing concern about the adverse health effects of PFAS exposure has researchers ...

Study finds evidence of 55 new chemicals in people

Scientists at UC San Francisco have detected 109 chemicals in a study of pregnant women, including 55 chemicals never before reported in people and 42 "mystery chemicals," whose sources and uses are unknown.

Winds spread PFAS pollution far from a manufacturing facility

Concerns about environmental and health risks of some fluorinated carbon compounds used to make non-stick coatings and fire-fighting foams have prompted manufacturers to develop substitutes, but these replacements are increasingly ...

A possible end to 'forever' chemicals

Synthetic chemicals known as per- and polyfluoroalkyls, or PFAS, contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products ...

Fecal excretion of PFAS by pets

Per- and polyfluoroalkyl substances (PFAS) are used in a wide range of consumer products, from pizza boxes to carpets to non-stick cookware. Therefore, it's not surprising that these water- and stain-repelling substances ...

PFASs from ski wax bioaccumulate at Nordic resort

With winter approaching in the Northern Hemisphere, many people are looking forward to hitting the slopes. However, a recent study suggests that ski wax applied during winter months could have consequences that stretch to ...

Compostable food containers could release PFAS into environment

Compostable food containers seem like a great idea: They degrade into nutrient-rich organic matter, reducing waste and the need for chemical fertilizers. But much of this packaging relies on per- and polyfluoroalkyl substances ...

Pollutants, pathogens could team up to make us sick

Many people view pollutants and pathogens as separate causes of illness. However, recent research indicates that the two can interact, changing how people and animals respond to infectious diseases. According to an article ...

Research targets PFOA threat to drinking water
