Volatile Organic

Due to the development of industrialization and urbanization, secondary pollution is becoming increasingly serious in the Yangtze River Delta. Volatile organic compounds (VOCs) are key precursors of the near-surface ozone, secondary organic aerosol (SOA), and other secondary pollutants. In this study, we chose a serious ozone pollution period (01 May–31 July 2017) in Jinshan, which is a petrochemical and industrial area in Shanghai. We explored the VOCs distribution characteristics and contribution to secondary pollutants via constructing a regional network based on wind patterns. We determined that dense pollutants were accumulated at adjacent sites under local circulation (LC), and pollution from petrochemical discharge was more serious than industry for all sites under southeast (SE) wind. We also found that cyclopentane, o-xylene, m/p-xylene, 1-3-butadiene, and 1-hexene were priority-controlled species as they were most vital to form secondary pollutants. This study proves that regional network analysis can be successfully applied to explore pollution characteristics and regional secondary pollutants formation.

Industrial Complexes

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.
