Over 30% of domestic soil contamination has occurred via petroleum products and complex oil. Moreover, contamination by complex oil is more intense than it is by a single petroleum product species. In this study, we analyzed sectional TPH (total petroleum hydrocarbon) pattern and sectional ratio of current domestically distributed petroleum products, such as kerosene, diesel, bunker C, and lubricant and complex oils, to determine pollution characteristics of the soil. In the TPH pattern, kerosene, which is a light distillate, had an early retention time, and lubricant oil, which is a heavy distillate, had a late retention time in the gas chromatogram. In addition, we obtained a complexly contaminated soil via diesel and lubricant oil from the Navy and inspected it for its ratio of complex oil species. The inspection results showed that this soil was contaminated with 85% diesel and 15% lubricant oil. The method developed in this study could be used to determine complex petroleum sources and ratios at sites with accidentally contaminated soil.

Over 60~70% of the domestic soil contamination have occurred by petroleum products. B T E X including benzene, toluene, ethylbenzene, xylene and total petroleum hydrocarbon (TPH) have to be inspected for the contaminated soil by petroleum products. An accurate contamination analysis is necessary to estimate the are of contaminated soil and also establish an appropriate purification scheme. In this study, we analyzed a sectional TPH pattern for current domestic distributed petroleum products. Also, the TPH content was analyzed by compensating the defect of current Korea standard analytic methods for soil where the analytic range is just for $C_8{\sim}C_{40}$. The light distillate petroleum products such as gasoline and solvent 1 showed the maximum of 85% difference in the TPH content between the standard analytic and improved methods.
