 BEIJING (AP) - Despite a persistent gray haze, officials said Tuesday an exercise that removed more than 1 million private vehicles a day from Beijing's gridlocked streets was a success that could mean a clearer sky during next summer's Olympics.
Humidity and wind conditions kept the pollution from dispersing, but the air during the four-day drill would have been much worse without the vehicle restrictions, said Du Shaozhong, the deputy director of the Chinese capital's Environmental Protection Bureau.
"The test was successful. These four days the wind speed was slow, while the humidity and temperature were high," Du told reporters, noting that a gray sky doesn't necessarily mean pollution is bad.
