Objectives: The concentrations and distribution characteristics of volatile organic compounds (VOCs) in an industrial complex and surrouding affected residential areas were investigated in an effort to support the efficient management of VOCs. Methods: The atmospheric concentrations of VOCs were analyzed at sites around the Sihwa-Banwol complex located in the cities of Siheung and Ansan and in the surrounding affected residential areas. The appearance of VOCs and the characteristics of their temporal and spatial distribution were evaluated. Results: The total VOC concentrations in the industrial complex were detected at 1.9-2.3 times higher than in the affected areas, but the daily VOCs distributions showed similar patterns in both sites. In particular, it was confirmed that the composition ratio of the VOCs and concentration fluctuations over time in the affected areas are similar to those in the adjacent industrial complex. VOC levels in the affected areas were higher than in residential areas in cities without an industrial complex. Conclusions: VOCs in residential areas near an industrial complex were highly distributed due to the influence of continuous pollutant emissions from the industrial complex. Therefore, the management of VOCs in the atmosphere of the affected area is important for identifying and managing the sources of VOCs detected in high concentrations in the industrial complex.
