Earlier this week, a few British newspapers ran stories about the implications of poor air quality in London and the impact it may have on athlete’s performance. The articles were a bit scant on details, but hinted at dangers for vulnerable populations and an increased risk of exercise-induced asthma during certain times of the day, especially for athletes. They cited London Air, a site that is tracking a number of important pollutants at sites throughout London.

They’ve got a remarkable amount of relatively easily accessible data on their site, and a special subsection catered towards visitors to London for the 2012 games. They’ve also created (in collaboration with the Environmental Health group at King’s College) free location-aware smartphone apps for Android and iOS that are impressive, easy to use, and comprehensive.
