Study: Beijing’s Air Worse Than At Past Olympics
Beijing’s notoriously dirty air was cleaner during last summer’s Olympic games, but pollution levels were still much worse than at recent Olympics, despite a massive Chinese cleanup campaign, a new report said.
Athletes in Beijing faced pollution levels that were up to 3.5 times higher than those in recent Olympic cities like Athens, Atlanta and Sydney, said the study published Friday in the journal Environmental Science and Technology. The pollution often exceeded what the World Health Organization considers safe.
The joint American-Chinese study — the first major one published on air pollution during the Olympics — also found that the weather, and not the Chinese government’s strict controls imposed in the run-up to the games, played the largest role in clearing the air.
