VOCs emission from a Ta-Shan Chemical Industrial Park in January 1-8, 2014 and summer (July 16-20, 2014) have been studied in this paper. VOCs were collected by the stainlessteel canisters and following pre-concentrate and analyzing by GC/MSD. The results showed that a total of 33 VOC species in winter samplers and 41 VOC species in summer samplers were detected. Among the 41 VOC species detected in the winter and summer samplers, 1-Butene and Ethane were the two most abundant compounds. Their highest average mean concentrations were 6013±1758 and 3188±1025 pptv in summer (contributed more than 12.5% and 4.8 % of the total VOC concentrations), and about 5895±1246 and 2763±789 pptv in winter (contributed more than12.9% and 7.8% of the total VOC concentrations), respectively. In winter, stack emission was found to be the main souce of VOCs emission, while in summer, fugitive emission become the primary source.
