China jumps Olympics air hurdle :

China has confirmed something that most people in Beijing for the Olympics already suspected - the city's air quality has been good.
Environmental officials say pollution levels have met expected standards on every day of the Olympics so far.
They say this is down to measures brought in to reduce emissions during the Olympics and Paralympics.
But one pollution expert says Beijing has also benefited from favourable weather conditions.
'Effective measures'
Du Shaozhong, of Beijing Municipal Environmental Protection Bureau, said air quality had been good on every day in August.
