In this study, measured volatile organic compounds (VOCs) in the vicinity of a petrochemical industrial complex to analyze the wind effect, estimate pollution sources by PMF model, and assess the hazards of the sources. At the receptor, the concentrations of formaldehyde, acetaldehyde, and acetone were high, and among the VOC groups, the contribution of OVOCs was the highest at 52.1% (24.9 µg/㎥ ). This was followed by the aromatics group at 27.1% (12.9 µg/㎥ ), the halogenated group at 11.0% (5.2 µg/㎥ ), the alkanes group at 9.5% (4.5 µg/㎥), and other groups at 0.4% (0.2 µg/㎥). The receptor was identified as the site where the VOC concentration linearly decreases as the wind speed increases. The main sources identified by the PMF model were as follow: traffic-related 29.6% (9.32 µg/㎥ ), background+solvent_2 (acetone) 26.3% (8.26 µg/㎥ ), petrochemical industry 22.4% (7.05 µg/㎥ ), solvent_3 (DCM, hexane) 12.5% (3.94 µg/㎥ ), and solvent_1 (MEK) 9.2% (2.88 µg/㎥ ). In the regression analysis results of the separated sources with wind speed, the pollution source with the highest coefficient of determination (R² ) was the petrochemical industry 0.8086, and the other sources were less than 0.6. The influence range of petrochemical industry source reaching the receptor site was estimated to be workplaces within a distance of approximately 3.0 to 3.1 km from the receptor site. As a result of the health risk assessment of sources, traffic- related source were judged to be priority management source because their relative contribution (carcinogenic 62%, non- carcinogenic 68%) was very high. Petrochemical industry source, which have a high correlation with wind speed, were found to have an increased impact on VOC hazards in the summer.
