Researchers get new view of how water and sulfur dioxide mix
High in the sky, water in clouds can act as a temptress to lure airborne pollutants such as sulfur dioxide into reactive aqueous particulates. Although this behavior is not incorporated into today's climate-modeling ...
New compounds discovered that are hundreds of times more mutagenic
(Phys.org) —Researchers at Oregon State University have discovered novel compounds produced by certain types of chemical reactions – such as those found in vehicle exhaust or grilling meat - that are ...
Black carbon—a major climate pollutant—also linked to cardiovascular health
Black carbon pollutants from wood smoke are known to trap heat near the earth's surface and warm the climate. A new study led by McGill Professor Jill Baumgartner suggests that black carbon may also increase ...
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.
Air pollution boosts NW Pacific cyclones, study finds
Surging air pollution from China and other fast-growing Asian economies has intensified winter cyclones in the northwest Pacific, scientists said Tuesday.
Non-equilibrium quantum states in atmospheric chemistry
(Phys.org)—Research that sheds new light on the microscopic chemical physics driving one of the most important reaction sequences in atmospheric chemistry is published in Science today by Dr David Glowac ...
Living under a flight path increases heart attack risk
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 ...
Air pollution stunts coral growth, research shows
A new study has found that pollution from fine particles in the air – mainly the result of burning coal or volcanic eruptions – can shade corals from sunlight and cool the surrounding water resulting ...
'Warming hole' delayed climate change over eastern United States: study
Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United Statesthat ...
Researchers estimate over two million deaths annually from air pollution
Over two million deaths occur each year as a direct result of human-caused outdoor air pollution, a new study has found.
Researchers pinpoint how trees play role in smog production
After years of scientific uncertainty and speculation, researchers at the University of North Carolina at Chapel Hill show exactly how trees help create one of society's predominant environmental and health ...
Study estimates extent to which air pollution in China shortens human lives
A high level of air pollution, in the form of particulates produced by burning coal, significantly shortens the lives of people exposed to it, according to a unique new study of China co-authored by an MIT economist.
WHO sets guidelines to reduce indoor pollution deaths
The World Health Organization on Wednesday announced its first-ever guidelines for indoor air pollution related to cooking, heating and lighting, a problem estimated to kill more than four million people per year.
