초록

Ambient air monitoring was performed during the period of May to December 2011 in Daesan area, where large petrochemical industrial complexes are located. The main objective of this study was to investigate the occurrence, ambient concentrations and seasonal variation of volatile organic compounds (VOC) at two sites in the vicinity of the industrial complexes and at a control site. A total of 72 VOC were determined by adsorption sampling and thermal desorption coupled with GC-MS. BTEX (benzene, toluene, ethylbenzene, xylenes), and styrene were detected in all the samples (n=336), while 25 VOC were detected more than 50% of the samples. VOC concentrations at industrial sites were significantly higher that those at the residential site (control site). However, there was no specific pattern of seasonal variations in the VOC concentrations. Average levels in the summer was the lowest among the four season’s averages, being attributed to the South wind during the season.
Hexane (1.83 ppb) was the most abundant VOC, followed by toluene (1.50 ppb), ethylacetate (1.11 ppb), benzene (0.77 ppb), styrene (0.66 ppb), m-/p-xylenes (0.58 ppb), and ethylbenzene (0.40 ppb). Analysis of Toxic Release Inventory (TRI) data revealed that VOC, listed as hazardous air pollutants (HAP), emitted from 15 industrial sources, such as petrochemical industries and oil refineries. This study is the first report regarding the comprehensive monitoring of VOC in the ambient air of the Daesan industrial complexes.
