Volatile organic compounds(VOCs) data collected in the atmosphere of a typical industrial park in Shanghai in year 2009~2015 were analyzed in this paper.It was found that concentration of TVOC was high in winter and low in spring and summer.48 kinds of VOCs were detected in the atmosphere of this region.Among them,ethyl acetate,n-heptane,heptanes,and toluene accounted for 30%,11%,10%,and 7%,respectively.According to the ratio of <i>T/B</i>,we can concluded that concentrations of VOC in the atmosphere of this industrial park and the residential areas around the industrial park are mainly affected by the volatility of organic solvents and motor vehicle exhaust emissions,respectively.
