PFAS 'forever chemicals' above drinking water guidelines in global source water      (via sciencedaily.com)     Original source 

PFAS (aka 'forever chemicals') are notoriously difficult to destroy. They've been linked to environmental and health issues, including some cancers, but a lot remains unknown about the true scale and potential impacts of the problem -- including how much is in our water supply. A new study assessed the levels of PFAS contamination in surface and ground water around the globe -- and found that much of our global source water exceeds PFAS safe drinking limits.

Adult fish struggle to bounce back in marine protected areas      (via sciencedaily.com)     Original source 

Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.

'Tug of war' tactic enhances chemical separations for critical materials      (via sciencedaily.com)     Original source 

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

Experiencing extreme weather predicts support for policies to mitigate effects of climate change      (via sciencedaily.com)     Original source 

Most Americans report having personally experienced the effects of extreme weather, according to new survey data. An analysis finds that a reported exposure to extreme weather is associated with support for a half-dozen pro-environmental government policies that are intended to mitigate the effects of climate change and are contained in the Inflation Reduction Act of 2022.
