上海大气环境压力及风险防控

Abstract:Since 1995, especially since 2005, Shanghai has attained great achievements in abating traditional air pollutants; however, at the same time, new-type air pollution problems such as PM2.5, VOC, oxygen and fetor is becoming more serious. These new-type air pollution risks mainly result from five respects: first, coal still accounts for the major part of Shanghai's energy consumption, responsible for most PM2.5 in this city; second, increasing cars emit a great amount of PM2.5, VOC and oxygen; third, expanding chemistry industry brings about a lot of VOC, oxygen and fetor; fourth, owing to city growth, some new neighborhoods are built too close to sewage and solid waste treatment plants; fifth, air pollutants from neighboring regions in the Yangtze Delta or East China exert negative influences on Shanghai. In order to mitigate air pollution risks in Shanghai, this paper puts forward some suggestions to related governmental agencies: first, accelerate increasing clean energies in the energy mix and reduce pollution in the process of burning coal; second, stringently control pollution from the automobile exhaust; third, attach importance to air pollution abatement in some key chemistry industry areas; fourth, adjust the city layout to separate highly-polluting facilities from neighborhoods farther; fifth, promote cooperation with neighboring provinces or cities in the Yangtze Delta in air pollution abatement.
