Electric drive vehicles have little impact on US pollutant emissions, study finds
(Phys.org) —A new study from North Carolina State University indicates that even a sharp increase in the use of electric drive passenger vehicles (EDVs) by 2050 would not significantly reduce emissions of ...
A win-win situation: Growing crops on photovoltaic farms
Growing agave and other carefully chosen plants amid photovoltaic panels could allow solar farms not only to collect sunlight for electricity but also to produce crops for biofuels, according to new computer ...
Scientific evidence shows need to regulate antimicrobial ingredients in consumer products
Does the widespread and still proliferating use of antimicrobial household products cause more harm than good to consumers and the environment? Evidence compiled in a new feature article published in the journal Environmental Sc ...
Researchers use neutrons, simulations to examine soil carbon
(Phys.org) —Carbon dioxide in the atmosphere may get the lion's share of attention in climate change discussions, but the biggest repository of carbon is actually underfoot: soils store an estimated 2.5 ...
Research clarifies health costs of air pollution from agriculture
(Phys.org) —Ammonia pollution from agricultural sources poses larger health costs than previously estimated, according to NASA-funded research.
Is natural gas a solution to mitigating climate change?
(Phys.org) —Methane, a key greenhouse gas, has more than doubled in volume in Earth's atmosphere since 1750. Its increase is believed to be a leading contributor to climate change. But where is the methane ...
Tracking air pollution aids policy makers
(Phys.org) —Recently, Beijing and the nearby Chinese provinces were veiled in smog that reduced visibility, induced health problems, and reached levels described as "beyond index."

Poison-breathing bacteria may be boon to industry, environment
(Phys.org) —Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive. Researchers ...
NASA satellite sees increase of India's sulfur dioxide emissions
(Phys.org) —Power plant emissions of sulfur dioxide – an atmospheric pollutant with both health and climate impacts – have increased across India in recent years, according to a new analysis of data ...
Research overturns assumption about mercury in the Arctic
For years, scientists have assumed that if mercury is high and increasing in fish in the North American and European Arctic, the same is true of fish elsewhere in the Arctic.
'Superbugs' found breeding in sewage plants
(Phys.org) —Tests at two wastewater treatment plants in northern China revealed antibiotic-resistant bacteria were not only escaping purification but also breeding and spreading their dangerous cargo.
Ethanol blends carry hidden risk
(Phys.org) —Blending more ethanol into fuel to cut air pollution from vehicles carries a hidden risk that toxic or even explosive gases may find their way into buildings, according to researchers at Rice ...
Radioactive shale gas contaminants found at wastewater discharge site
Elevated levels of radioactivity, salts and metals have been found in river water and sediments at a site where treated water from oil and gas operations is discharged into a western Pennsylvania creek.
