Study finds no safe level for ozone
Even at very low levels, ozone-the principal ingredient in smog-increases the risk of premature death, according to a nationwide study to be published in the April edition of the journal Environmental Health Perspectives. view more (2006-02-17)
Winds trigger increases in ozone destroying gases in upper stratosphere
A surprising new University of Colorado at Boulder study indicates winds circling high above the far Northern Hemisphere have a much greater impact on upper stratospheric ozone levels than scientists had thought. view more (2006-09-29)
Ozone levels drop when hurricanes are strengthening
Scientists are continually exploring different aspects of hurricanes to increase the understanding of how they behave. Recently, NASA-funded scientists from Florida State University looked at ozone around hurricanes and found that ozone levels drop as a hurricane is intensifying. view more (2005-06-08)
Will an ozone hole develop over the Arctic? A press briefing at the research site
The Theseo presentation will mark the beginning of a decisive period in the development of the Arctic stratosphere. Over the last ten years or so, cold winters have been a prerequisite for maximum ozone depletion, and scientists now understand the chemical processes in the stratosphere that cause the phenomenon. It has been very cold during... view more... (2000-01-21)
NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic. view more (2006-03-15)
New simulation shows consequences of a world without Earth's natural sunscreen
Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five... view more... (2009-03-19)
New policies needed to combat Global Change, says Commissioner Wallström
Never before have policy makers faced a more challenging task than responding to global change, said EU Environment Commissioner Margot Wallström, in an article in the International Herald Tribune today (http://www.iht.com/articles/125563.html) and in a statement made for the launch of a new book on global change*... view more...

NOAA study shows nitrous oxide now top ozone-depleting emission
Nitrous oxide has now become the largest ozone-depleting substance emitted through human activities, and is expected to remain the largest throughout the 21st century, NOAA scientists say in a new study. view more (2009-08-28)
Outdoor Team Sports In High-Ozone Environments Could Triple Asthma Risk In Children (p 386)
A US study in this week's issue of THE LANCET highlights how children playing outdoor team sports in areas of high ozone concentration could be three times more likely to develop asthma than children who do not take part in sporting activities. Asthma is the most common chronic disease of childhood; its prevalence and incidence have been... view more... (2002-01-30)
Even healthy lungs labor at acceptable ozone levels
Ozone exposure, even at levels deemed safe by current clean air standards, can have a significant and negative effect on lung function, according to researchers at the University of California Davis. view more (2009-07-24)
Grape expectations for healthier wine
A new technique that uses ozone to preserve grapes could help prevent allergies and boost healthy compounds at the same time, reports Jennifer Rohn in Chemistry & Industry, the magazine of the SCI. view more (2007-02-12)
Global warming may delay recovery of stratospheric ozone
Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health. view more (2009-02-05)
Slow Electrons are "killing" Ozone
Outstanding new discoveries in ion physics Innsbruck/Vienna (Austrian Science Fund) - Tilmann M'Īrk from the Institute of Ion Physics at the University of Innsbruck and his team have, with the support of the Austrian Science Fund, developed unique methods and equipment to examine the interaction of electrons with atoms, molecules and clusters. And... view more... (2001-10-15)
FSU meteorologists' work may lead to better tracking of hurricanes
Scientists are continually exploring different aspects of hurricanes to increase the understanding of how they behave. Recently, two NASA-funded scientists from Florida State University analyzed ozone levels surrounding hurricanes. Their work could lead to better methods of forecasting the paths of the deadly storms. view more (2005-06-09)
Gender may play role in recovery from pneumonia after ozone exposure
Does air pollution have a bigger effect on the immune system of females than males? It did among mice exposed to ozone -- a major component in air pollution that is known to negatively affect lung function -- and then infected with pneumonia, as significantly more females died from the infection than males. view more (2007-06-26)
EPA ozone pollution standards 'unhealthy for America,' says American Thoracic Society president
David H. Ingbar MD, president of the American Thoracic Society, today called the proposed standards issued by the Environmental Protection Agency for ozone pollution-commonly known as smog-"unhealthy for America's kids, unhealthy for America's seniors, and unhealthy for America." view more (2007-06-25)
Mountainous plateau creates ozone 'halo' around Tibet
Not only is the air around the world's highest mountains thin, but it's thick with ozone, says a new study from University of Toronto researchers. view more (2005-12-08)
Skin oil -- ozone interactions worsen air quality in airplanes
Airline passengers and crews who gripe about poor cabin air quality could have a new culprit to blame: the oils on their skin, hair and clothing. view more (2007-09-06)

Ozone depletes oil seed rape productivity
High ozone conditions cause a 30% decrease in yield and an increase in the concentration of a group of toxic compounds within oilseed rape plants. view more (2009-06-29)
