[Anthropogenic VOC emission inventory and contribution from industrial sources in Ningbo].

Ningbo is an important industrial city in eastern China and is also the economic center in the south wing of the Yangtze River Delta (YRD). Recently, the VOC emissions from the local industrial activities and its effects on both the regional air quality and people's health were getting more and more attention. The anthropogenic VOC emission inventory of Ningbo in 2010 was established with collecting comprehensive activity data of anthropogenic sources. Furthermore, the industrial sectors were studied and the significant industries were identified with their contribution quantified. The result shows that the amount of anthropogenic VOC emission in Ningbo in 2010 is 176 kt. Industry, transportation and residential source are the most important VOC anthropogenic sources in Ningbo, which accounted for 62.0%, 17.2% and 15.5% respectively. Synthetic materials manufacturing and refined petroleum products manufacturing are the most important VOC emitting industries, which contributed 18.6% and 13.1% of the total VOC amount respectively, signifying the influence of these two industries to the VOC emissions in Ningbo.
