Climate change and air pollution will combine to curb food supplies
Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution—specifically ozone ...
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.
The causes of China's record level fine particulate pollution in winter 2013
At the beginning of 2013 a greyish-brown blanket of smog lay over large areas of China for several months. The fine particle pollution was higher by 1 to 2 orders of magnitude than the levels normally measured ...
Molting tougher on the mayfly than previously thought
It's not easy being a mayfly. Mayflies are insects that spend most of their life in water and provide clues about the health of our streams and other waterways.
Two-stroke scooters are 'super-polluters', study finds
Scientists on Tuesday pointed the finger at two-stroke scooters, a ubiquitous sight in developing countries, for massively contributing to local air pollution.
Chemists observe key reaction for producing 'atmosphere's detergent'
Earth's atmosphere is a complicated dance of molecules. The chemical output of plants, animals and human industry rise into the air and pair off in sequences of chemical reactions. Such processes help maintain ...
Air pollution killed seven million people in 2012, WHO says (Update)
Air pollution by sources from cooking fires to auto fumes has become the globe's worst environmental health problem, contributing to a shocking seven million deaths worldwide, the UN said Tuesday.
Dangerous nitrogen pollution could be halved
The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Chemical compounds containing reactive nitrogen are major drivers of air ...
Artisanal gold mining and its health risks
Researchers from the UPM have characterized the health risks derived from the usage of mercury in artisanal gold mining in Colombia through probabilistic models.
Measuring ice particles and water vapor in the upper troposphere
A Colorado State University-led research team is designing and building a new instrument to help NASA measure ice particles in clouds and water vapor in the upper troposphere.
US clean-air efforts stay on target, analysis shows
National efforts in the last decade to clear the air of dangerous particulate matter have been so successful that most urban areas have already attained the next benchmark, according to new research by Rice ...
Keystone carbon pollution more than figured, study finds (Update)
The much-debated Keystone XL pipeline could produce four times more global warming pollution than the State Department calculated earlier this year, a new study concludes.
Asian air pollution affect Pacific Ocean storms
In the first study of its kind, scientists have compared air pollution rates from 1850 to 2000 and found that anthropogenic (man-made) particles from Asia impact the Pacific storm track that can influence ...
Novel system uses microbes to treat, extract power from wastewater
Each day, breweries and wineries produce thousands of gallons of wastewater, which is either poured down the drain or shipped to treatment facilities at a high cost to the companies.
