Researchers at the University of New Hampshire have conducted two of the first studies in New England to collectively show that toxic man-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up in the environment differently after being processed through wastewater treatment facilities—making it more challenging to set acceptable screening levels.
Researchers reporting in ACS’ Environmental Science & Technology have used a combination of laboratory experiments and computer modeling to reveal that PFASs can interact with the estrogen receptor in different ways to influence estrogen-controlled gene expression.
Researchers reporting in ACS’ Environmental Science & Technology have studied the transport of 29 PFAS into and out of the Arctic Ocean, detecting a newer compound for the first time in Arctic seawater.
Detecting the presence of harmful manmade chemicals known PFAS in water and samples may soon be possible using a portable field device.
Concerns about environmental and health risks of some fluorinated carbon compounds have prompted manufacturers to develop substitutes, but these replacements are increasingly coming under fire themselves. Scientists have been studying how widely these chemicals have contaminated the environment.
The first human study to link blood levels of “forever” chemicals known as PFAS in pregnant women with the risk of obesity in their granddaughters is described in an ENDO 2020 abstract that will be published in the Journal of the Endocrine Society.
Researchers reporting in ACS’ Environmental Science & Technology have compared PFAS in the serum of female firefighters and female office workers, finding higher levels of three compounds in the firefighters.
