Olympic village opens amidst doping, pollution concerns

The Olympic village in Beijing opened its doors to hundreds of athletes on Sunday, ahead of the Games which begin on August 8, with the Chinese delegation being the first team to check in to the athlete's compound. But with the build up to the Games gathering steam, concerns about the continued problem of doping as well as poor air quality hang over the Olympic village.

International Olympic Committee president Jacques Rogge, interviewed in the Belgian newspaper De Standaard, said he expected 40 athletes to be caught doping during the Beijing Games. Rogge based his statements on increased doping controls, when compared with previous Olympic Games. At the Sydney Games in 2000, there were 12 positives from 2,500 tests. This year, there will be 4,500 controls performed at the Olympic Games.
