Researchers announced today that chemical sunscreens may be far more dangerous than previously revealed, and that children may be even more at risk from these chemicals than adults. The study in today’s medical journal JAMA revealed that common sunscreen products containing avobenzone, oxybenzone, ecamsule and octocrylene need much more research. Blood concentration of these chemicals has for the first time been studied and found, after just one day’s use. Serum … [more…]
Exposure to emerging contaminants, even at extremely low doses, can cause adverse health effects for humans, including endocrine disruption which can lead to developmental malformations, interference with reproduction, increased cancer risk and disturbances in the immune and nervous system functions. These emerging contaminants include pharmaceuticals and personal care products, hormones, perfluorinated alkyls and volatile organics, and they may pose a threat to both the environment and human health. … [more…]
UC Berkeley engineers have created a new way to remove contaminants from storm water, potentially addressing the needs of water-stressed communities that are searching for ways to tap the abundant and yet underused source of fresh drinking water.
Using a mineral-coated sand that reacts with and destroys organic pollutants, the researchers have … [more…]
Hydraulic fracturing has enabled a domestic oil and gas boom in the USA, but its rapid growth has raised questions about what to do with the billions of gallons of wastewater that result.
Researchers now report that treating the wastewater and releasing it into surface waters has led to the contamination of a Pennsylvania watershed with radioactive material and endocrine-disrupting chemicals. The study appears in ACS’ journal Environmental Science & … [more…]
