The Clues for Cleaner Water      (via sciencedaily.com)     Original source 

By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.

Quantifying U.S. health impacts from gas stoves      (via sciencedaily.com)     Original source 

A new study of air pollution in U.S. homes reveals how much gas and propane stoves increase people's exposure to nitrogen dioxide, a pollutant linked to childhood asthma. Even in bedrooms far from kitchens, concentrations frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off.

Oil palm plantations are driving massive downstream impact to watershed      (via sciencedaily.com)     Original source 

The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.

Human activity is causing toxic thallium to enter the Baltic sea, according to new study      (via sciencedaily.com)     Original source 

Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.
