Ambient air quality monitoring was carried out during the period of May 2008 to January 2009 in Yeosu-Gwangyang area, where large industrial complexes are located. The main objective of this study was to investigate the ambient concentrations and seasonal variation of particulate polycyclic aromatic hydrocarbons (PAHs) and phthalate compounds within and around the industrial areas of Yeosu and Gwangyang cities. Total suspended particles (TSP) were collected at five sites (two residential, two industrial, and one control sites) by high-volume samplers, and a total of 36 PAHs and 6 phthalates were extracted from the TSP samples, and then determined by GC/MS. There was no significant difference in TSP concentrations both seasonally and spatially. However, PAH concentrations were generally higher in Gwangyang than in Yeosu, attributing to the large iron-steel industrial complex. The average levels of benzo[a]pyrene (BaP) were 0.72 and 0.77 ng/m³ at two monitoring sites in Gwangyang, while 0.67 and 0.38 ng/m³ at two sites in Yeosu. The results showed that the most significant season for the PAH levels appeared to be winter, followed by autumn, spring, and summer. The average concentrations of PAHs in winter were 4~7 times higher than those in spring and autumn, and 7~10 times higher than those in summer. The overall average concentration of BaP (0.59 ng/m³) did not exceeded the European Union’s target value of 1 ng/m³ as an annual average. Among the phthalates, di-2-ethylhexyl phthalate (DEHP) appeared to be the most abundant one, followed by di-butyl phthalate (DBP). The spatial and seasonal variations in the concentrations of phthalates showed clearly different patterns from those of PAHs, indicating that the ambient levels of these compounds were affected by fugitive emission sources and temperatures. PAH levels in the Yeosu-Gwangyang area were evaluated to be relatively higher than those measured in other areas in Korea. Therefore, from the viewpoint of hazardous air pollutants, a comprehensive air quality management strategy is required to reduce the levels of PAHs and phthalates in this ‘bay’ area, which is very vulnerable to air pollution due to adverse geographical conditions.
