<p>Harvard researchers estimated that before humans started pumping mercury into the atmosphere, it contained on average about 580 megagrams of mercury. However, in 2015, independent research that looked at all available atmospheric measurements estimated the atmospheric mercury reservoir was about 4,000 Mg — nearly 7 times larger than the natural condition estimated in this study.</p> <p> </p>
Earlier this year, the US Environmental Protection Agency proposed maximum allowable levels in drinking water for six PFAS (per- and polyfluoroalkyl substances) – so-called forever chemicals. But the draft standards do not account for half of the PFAS at contaminated sites across the country.
NORTH Wales Road Runners collected nine Regional Championship medals at the tough Anglesey half-marathon on Sunday (March 6), including four gold,…
Uncovering Hidden Forever Chemicals New tool finds and fingerprints previously undetected PFAS compounds in watersheds on Cape Cod Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) found large quantities of previously undetectable compounds from the family of chemicals known as PFAS in six watersheds on Cape Cod using a new method to quantify and identify PFAS compounds. Exposures to some PFAS, widely used for their ability to repel heat, water, and oil, are linked to a range of health risks including cancer, immune suppression, diabetes, and low i...
E-Mail Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) found large quantities of previously undetectable compounds from the family of chemicals known as PFAS in six watersheds on Cape Cod using a new method to quantify and identify PFAS compounds. Exposures to some PFAS, widely used for their ability to repel heat, water, and oil, are linked to a range of health risks including cancer, immune suppression, diabetes, and low infant birth weight. The new testing method revealed large quantities of previously undetected PFAS from fire-retardant foa...
