Wildfires Cause Ozone Pollution to Violate Health Standards, New Study Shows
Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes.   view more (2008-10-10)

Record cold winter may increase ozone hole over North Europe
European scientists confirmed that Arctic high atmosphere is reaching the lowest ever temperatures this winter, warning that destruction of the protective ozone layer is substantially increased under very cold conditions. First signs of ozone loss have already been detected. The ozone... view more (2005-01-31)

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)

Thanks to ESA, KNMI offers a UV forecasting Service
A unique new service which harnesses satellite data to powerful high-speed computing could soon lead to much improved weather forecasts and help make basking in the sun a lot safer. The "fast ozone profile" service developed by the Royal Netherlands Meteorological Institute (KNMI) within the ESA... view more (2001-03-26)

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... view more (2000-01-21)

Indoor air purifiers that produce even small amounts of ozone may be risky for health
In a small, poorly ventilated room, an indoor air purifier that produces even a few milligrams of ozone per hour can create an ozone level that exceeds public health standards.   view more (2006-05-10)

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)

SARS From Outer Space? (p 1832)
An alternative theory to the origin of severe acute respiratory syndrome (SARS) is proposed by scientists in a letter in this week's issue of THE LANCET--that the disease may have originated in outer space. Chandra Wickramasinghe from Cardiff University, UK, and colleagues describe how around a... view more (2003-05-21)

Laughing Gas in a Vicious Circle
Italian researchers discover another mechanism for the formation of atmospheric N2O Summer smog, the ozone hole, the greenhouse effect – the complex web of chemical reactions in the atmosphere, which leads to manifold environmental problems, is still not fully cleared up. In a tricky way, a... view more (2001-05-15)

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... view more (2002-01-30)

As ozone hole approaches annual peak, NASA scientists reveal latest information and images
In 1987, the United States joined several other nations in signing the Montreal Protocol, an international treaty designed to protect the Earth's ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion.   view more (2006-09-29)

Ozone layer decline leveling off, according to new study
A new global study involving long-term data from satellites and ground stations indicates Earth's ozone layer, while still severely depleted following decades of thinning from industrial chemicals in the atmosphere, is no longer in decline.   view more (2005-08-30)

Sea salt worsens coastal air pollution: study
Air pollution in the world's busiest ports and shipping regions may be markedly worse than previously suspected, according to a new study showing that industrial and shipping pollution is exacerbated when it combines with sunshine and salty sea air.   view more (2008-04-09)

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... 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... 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... 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)

Polar clouds take a 'bite' out of meteoric iron
Polar clouds are known to play a major role in the destruction of Earth's protective ozone layer, creating the springtime 'ozone hole' above Antarctica. Now, scientists have found that polar clouds also play a significant role in removing meteoric iron from Earth's atmosphere. Polar clouds have... view more (2004-04-14)

Underground Nuclear Explosions Deteriorate The Ozone Layer
Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere... view more (2002-08-16)

Long-Term ozone measurements from Space assured
The EUMETSAT Polar System, and the ESA METOP-1 Programme together form a co-operative venture between the two organisations, and lead to the launch of the first METOP satellite in mid-2003. The system provides operational meteorological data from polar orbiting satellites, to complement and... view more (2000-03-05)

Ozone shuts down early immune response in lungs and body
As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria.   view more (2007-10-01)

Fires in Alaska and Canada caused sharp increase in Houston's ozone level
Forest fires that ravaged parts of eastern Alaska and western Canada in 2004 exacerbated the already-high levels of ozone pollution in Houston, Texas, some 5,000 kilometers [3,000 miles] away.   view more (2006-09-25)

Antarctic forecast: premature break-up of ozone hole this week
Based on satellite data from the European Space Agency, the national meteorological centre of the Netherlands predicts the Antarctic ozone hole will break apart this week, months earlier than usual.
