Objectives : Volatile organic compounds discharged from industrial complexes need to be managed. They make PM, O3 etc from NOx and photochemical reaction in the atmosphere and become a major source of odor. Methods : The environmental impacts around Sasang industrial area and Shinpyeong-Jangrim general industrial complex were investigated by SIFT-MS, which can continuously real-time measure air pollutants such as volatile organic compounds. A map of air pollution around industrial complexes was drawn up and major impact substances were identified. Results and Discussion : Benzene was all within the atmospheric standard and hexane was the highest concentration. Alkane, aldehyde and alcohol groups were relatively high in Sasang industrial area. Amide and thiol groups were relatively high in Shinpyeong-Jangrim general industrial complex. Most of volatile organic compounds were high in May, and some odorous substances were high in summer. The pollution map of Sasang industrial area was high around Nakdong-daero and Gamjeoncheon. And the pollution map of Shinpyeong-Jangrim general industrial complex was various according to the source of discharge, but the northern point with dyeing wastewater treatment plant was relatively high. The correlation between PM-2.5 and VOCs was investigated at a low value, and further research on fixed points should be conducted. Conclusions : As a result of analyzing 84 types of SIFT-MS and 2 types of OPC, most items in Sasang industrial area were higher concentration than those in Shinpyeong-Jangrim general industrial complex.
