YU Yi yong
|Based on Nanjing air quality monitoring results during the Asian Youth Games (AYG) in August, the air quality was evaluated and analyzed and the relevant reasons of air quality change were discussed with the temporary control measures and the meteorological conditions. The results showed that the air quality in Nanjing in August achieved a moderate level and was further improved during the AYG. According the Air Quality Standards of different pollutants, many of them reached moderate levels and the pollution decreased obviously compared with the same period of the last year. This could be attributable to steps taken to reduce emissions from industrial point sources as well as temporary control measures on motor vehicle flow and dust of non point sources. Additionally, general meteorological conditions during the period of the games were beneficial to the diffusion of pollutants.
