Air pollution from bus exhaust (one of main sources of urban haze) in Shantou City, Guangdong Province was surveyed, and the purification effect of a new device for removing soot particulates from bus exhaust was analyzed. The results show that the smoke intensity of all buses surveyed averages 3.59 m - 1, exceeding the limit, and the maximum is 5.7 times higher than the limit. Among the buses inspected, the smoke intensity of 37% of buses is not up to standard. The removal rate of soot particulates from various buses equipped with the purification device averages 63.6%, and some buses are up to standard after their exhaust are purified, showing that the device has good purification effect. Therefore, installing the purification device in a bus is an effective way to control air pollution from bus exhaust and haze in a city. [ABSTRACT FROM AUTHOR]
