Less than a week from the opening ceremonies, allergists are warning that some Olympic athletes may suffer breathing problems due to air pollution in London.
The amount of nitrogen dioxide in London is comparable to the level of nitrogen dioxide in Beijing before Beijing banned half of the cars in preparation for the Games, and London has done little to control traffic, says Dr. William Silvers, an allergy specialist and a member of the American Academy of Allergy, Asthma & Immunology (AAAAI).
Demanding workouts in the polluted air could spell trouble particularly for those athletes that already have conditions such as asthma or exercise-induced bronchoconstriction (EIB), a narrowing of the airways that makes it hard to move air out of the lungs, according to AAAAI.

The actual number of deaths from the 2009 H1N1 pandemic might have been more than 15 times higher than previously thought, according to a study released on Monday.
When the new H1N1 virus, often referred to as swine flu, spread around the world three years ago, 18,500 deaths were reported to the World Health Organization in the first 16 months of the pandemic. Based on this new study, published online in The Lancet Infectious Diseases, researchers estimate 284,400 people actually died in the first year the virus was circulating around the world.
According to a model developed by the study authors, the actual number of deaths linked to the H1N1 flu virus could range anywhere from 151,700 to 575,400. Lead study author Dr. Fatimah Dawood says she and her colleagues used three types of data to come up with their estimates:
