INTERNATIONAL Olympic Committee (IOC) said on Tuesday the dangers posed by pollution in Beijing had been exaggerated, as some competitors arrived for the Games wearing masks to protect their lungs.

The Beijing authorities have removed one million of the city’s 3.3 million cars from the roads and shut down more than 100 polluting factories and building sites in a concerted attempt to clear the city’s notorious smog.

With just three days to go before the Games opening ceremony in the Chinese capital, visibility started off poor in the morning before clearing later in the day to reveal traces of blue sky. The IOC’s medical commission chairman, Arne Ljungqvist, said pollution levels were not as bad as first feared and blamed the media for exaggerating the issue.

“I’m confident the air quality will not prove to pose major problems to the athletes and to the visitors in Beijing,” Ljungqvist said. Ljungqvist said media coverage highlighting the pollution had convinced stars such as Ethiopian Haile Gebrselassie and British marathon runner Paula Radcliffe that competing here might damage their health.

IOC chief Jacques Rogge warned last year that poor air during the Games could result in the suspension of some events, particularly endurance races such as the marathon. Despite the upbeat assessment, members of the US cycling team were seen arriving at Beijing airport wearing masks, and there was widespread concern among athletes over the effects of the poor air

quality.

“Very bad,” Turkish junior world weightlifting champion Sibel Ozkan said, covering her nose and mouth with a cupped hand, when asked about the pollution. Indonesian weightlifting team official Syafraidi Cut Ali said his squad were under strict instructions to stay in the open air as little as possible. “We stay in our bedrooms and the dining rooms, not in the open,” Ali said. “It is a problem.”

Spanish cyclist Alejandro Valverde said the combination of the air quality, the humidity and the intense heat would make racing in Beijing during the Olympics very demanding.

“When we got off the plane we immediately noticed the pollution,” he said. However some athletes said the air quality was not as bad as they had feared. New Zealand world champion rower Mahe Drysdale, speaking from the purpose-built Shunyi course on the outskirts of the city, said he was pleasantly surprised. “I was up here last September and the smog was a lot worse then,” said Drysdale. “They’ve done a good job clearing it up.”

China Environmental Monitoring Centre’s daily reading rated the air quality as grade two on Tuesday —“fairly good” on its own scale. However, environmental groups say China’s air quality standards do not address several key factors including levels of ozone, which can be harmful.
