2007년 태안 원유유출사고 주변지역의 지정악취성분들에 대한 예비조사

Abstract

In this study, the distribution of offensive odorants in ambient air was measured from four offshore sites near the site of the Hebei Spirit oil spill accident that took place on Dec. 2007. In order to investigate the air quality change due to oil spill accident, the concentrations of major odorants were measured during two field campaigns held at 100 hrs and one month after the accident (after an extensive clean-up process). The results of our analysis confirmed that the concentration levels of most individual odorants analyzed in this study were not high enough to contribute to the strong malodor that persisted in the study area, at least during the initial field campaign. However, the dilution to threshold (D/T) ratios determined from the identical samples confirmed that the odorant pollution was significant in the early phase of the oil spill accident. The overall results of our study suggest that the identification and improvement of measurement techniques for the odorants that are directly released due to the oil spill accident is of prior task to diagnose its environmental significance.
