The chemicals called “PFAS” have been in the news a lot lately — like the recent revelation that the U.S. Environmental Protection Agency was allowing PFAS-contaminated water to be treated in Lowell and discharged into the Merrimack River, or the news that chemical giant 3M is suing the state of New Hampshire over the state’s strict PFAS drinking water standards.

At first, teachers at Sky Valley Education Center simply evacuated students and used fans to clear the air when the fluorescent lights caught fire or smoked with noxious fumes. When black oil dripped onto desks and floors, they caught leaks with a bucket and duct-taped oil-stained carpets. Then came the tests that confirmed their suspicions about the light ballasts. More:

PFAS chemicals have been identified in synthetic turf, according to lab tests performed on several samples of the artificial grass. The presence of the chemicals, members of a class that has been associated with multiple health problems, including cancer, adds to growing concerns about the grass replacement that covers many thousands of acres in parks, schools, professional sports stadiums, and practice fields around the U.S. More:

If you’re a new parent, it can be confusing to keep up with the latest recommendations about how to give your baby a healthy start. As scientists learn more about the dangers of toxic chemical exposure to babies’ developing bodies and brains, some products haven’t stood the test of time.

The chemicals caused lab rats to lose weight. When pregnant rats were exposed to it, their pups lost weight, too, and their pups’ skulls, ribs, and pelvises tended to develop abnormally. The compound, referred to by the number “647-42-7” in Environmental Protection Agency records, also caused discoloration of the teeth, increased liver weights, decreased how much their infants nursed, and lowered the animals’ red blood cell counts.

Scientists have discovered that a soil microbe commonly found in New Jersey wetlands can break down one of the toughest class of pollutants, known as per- and polyfluoroalkyl substances, or PFAS. Often referred to as “forever chemicals,” PFAS are found in household products from non-stick pans, to dental floss, to water-repellant fabric. More:

Bottlenose dolphins in the Channel have been found to carry a “toxic cocktail” of chemicals in their bodies, some of which have been banned for decades and which may be harming the marine mammals’ health, scientists have said. Belgian and French scientists said they detected high accumulations of industrial fluids and mercury in the blubber and skin of dolphins in the waters off the north-west coast of France. More:

For more than 20 years, the eastern Michigan town of Lapeer sent leftover sludge from its sewage treatment plant to area farms, supplying them with high-quality, free fertilizer while avoiding the expense of disposal elsewhere. But state inspectors ordered a halt to the practice in 2017 after learning the material was laced with one of the potentially harmful chemicals known collectively as PFAS, which are turning up in drinking water and some foods across the U.S. More:
