Current computer models may underestimate levels of ground-level ozone A team of scientists has, for the first time, completely characterized an important chemical reaction that is critical to the formation of ground-level ozone in urban areas. The team's results indicate that computer models may be underestimating ozone levels in urban areas during episodes of poor air quality (smoggy days) by as much as five to 10 percent. Ground level ozone poses significant health hazards to people,...

Exposure to an increased level of air pollutants, especially nitrogen dioxide, has been associated with lower likelihoods of successful pregnancy among women undergoing in vitro fertilization, according to a team of fertility researchers. The team examined the outcomes of the first pregnancy attempt of 7,403 women undergoing IVF at Penn State Milton S. Hershey Medical Center, Hershey, Pa.; Shady Grove Fertility, Rockville, Md.; and Columbia University College of Physicians and Surgeons, New...

United Kingdom study findings show that traffic-related air pollution may be linked to a higher death rate among people who initially survived strokes, according to a recent Reuters report. Dr. Ravi Maheswaran at the University of Sheffield, along with colleagues, found more deaths among those exposed to higher estimated traffic-related pollution for over a decade.  They studied 3320 men and women living in a specific south London region that had a first stroke between 1995 and 2005....

Childhood asthma rates could increase as much as 30 percent with exposure to higher levels of traffic-related air pollution, a California study suggests. The study, published in the journal of Environmental Health Perspectives, is the latest to come from the Southern California Children's Health Study, a project pioneered by the Air Resources Board in the early 1990s. The eight-year study followed 217 non-asthmatic children from a wide area of Southern California. Home air monitors allowed...

High levels of stove gas emissions can be added to the list of indoor pollutants that aggravate asthma of inner-city children, U.S. researchers said. Researchers at The Johns Hopkins University said that nitrogen dioxide, compared the frequency and intensity of coughing, wheezing, shortness of breath and chest tightness to nitrogen dioxide levels inside the inner-city homes of 150 Baltimore children 2 to 6 years old. A report, published in the Environmental Health Perspectives, found asthma...

By David James IT has infuriated traders, been welcomed by shoppers and criticised by drivers, but one thing has not been affected by St Mary Street's part-pedestrianisation - pollution. The city's annual air-quality report has revealed banning private cars from the busy shopping street has made no difference to its long-standing nitrogen dioxide problem. Reducing pollution was cited last year as one of the key reasons for making the traffic changes as part of a bid to make the area...

NEW YORK (Reuters Health) - High outdoor levels of nitrogen dioxide apparently raise the risk of sudden infant death syndrome (SIDS), according to California-based researchers. Dr. H. Klonoff-Cohen, from the University of California San Diego at La Jolla, and colleagues linked air pollutant data obtained from the California Air Resources Board with occurrences of SIDS. The study, in the Archives of Disease in Childhood, involved 169 infants born between 1988 and 1992 who died suddenly and...
