From Wall Street Journal:
In the latest blow to China’s Olympic plans, the International Olympic Committee, citing its own medical research, said air pollution could pose a risk to the health of athletes who participate in endurance events such as the marathon and triathlon at the summer Olympic Games in Beijing.
The IOC’s medical commission recently analyzed air-quality data recorded by the Beijing Environment Protection Bureau in August, when test athletic events were held in the Chinese capital. The commission found that outdoor endurance events — defined as those that include at least an hour of continuous, high-intensity physical effort — may pose some risk to athletes in Beijing.
