Air quality monitors 'were not moved'

Beijing's air pollution monitoring stations in the downtown area remain where they were, the environmental chief of the Olympic organizing committee said yesterday.

"I am not aware of any of the monitors having been relocated," Yu Xiaoxuan, BOCOG's environmental director, said.

Yu was responding to an article in the Wall Street Journal in February that claimed the Beijing environmental protection bureau had manipulated the air quality index by removing monitoring equipment from heavily polluted areas.
