A comprehensive classification method for VOC emission sources to tackle air pollution based on VOC species reactivity and emission amounts

The VOC source profiles were examined for furniture coating, auto coating, print, power plant, and coking plant in Beijing-Tianjin-Hebei (BTH) region. The VOC source classification method was built, the VOCs emission amount index (NEA) and the source reactivity index (NSR) was chosen as the factors in the method, and was applied in BTH region. It was found that gasoline vehicle emission of Beijing was the Grade I VOCs sources in BTH region.124
