Abstract
Soil samples used in this study were taken from the site at which diesel spill accident had occurred in 1995. It was confirmed that all of soil samples were contaminated with diesel which was going on weathering. The concentrations of diesel in soils were determined by Korea standard method revised in July 1999 (Method 1) and US EPA method 8015b (Method 2). Some additional soil samples were analyzed with Korea standard method revised in July 2002 (Method 3) to compare the accuracy and reproducibility with Method 2. The only four of forty-six samples were determined when the analysis carried out according to Method 1 while forty-three of forty-six samples had the value above criterion (2000mg kg$^{-1}$ ) according to Method 2. There were no significant differences between the results of the analysis by Method 2 and Method 3. Based on these results, Method 2 and 3 were more appropriate than Method 1 for the determination of weathered diesel in soil. Method 2 had almost equivalent accuracy and reproducibility to Method 3.
