Abstract
The main objective of this study is to assess the compatibility between Korean ministry of environment (KME) standard and ISO (KS I ISO) standard for the determination of BTEX and TPH content in soil. We carried out comparison analysis for both methods using CRM and matrix spiked samples. In case of GC-MS analysis for BTEX, we got statistically (significance level: 0.05) the same results from KME standard (ES 07600.1) and ISO standard (KS I ISO 15009). However, it showed statistically (significance level: 0.05) different results when TPH was analyzed by KME standard (ES 07552.1) and ISO standard (KS I ISO 16703). To clarify the reason why both methods produced different results for TPH content, we also did some additional experiments in terms of differences in extraction, clean-up and target hydrocarbon range. Extraction with polar and non-polar compounds mixed solvent (acetone+n-heptane) of KS I ISO 16703 showed higher extraction efficiency than with only non polar solvent (dichloromethane) extraction of ES 07552.1 by about 9%. While column type clean-up of KS I ISO 16703 showed the reduction in TPH content between before and after clean-up, batch type of clean-up of ES 07552.1 did not show any changes in TPH content through clean-up process. The target hydrocarbon range of ES 07552.1 and KS I ISO 16703 is C8C40 and C10C40, respectively. From this point of view, kerosene and JP-8 contaminated soil showed higher RPD (relative producibility deviation) values between results by both method than that of lubricant or diesel contaminated soil. The higher content of hydrocarbon (C8C10) in kerosene and JP-8 played an important role in increasing RPD values in addition to the effects caused by different solvents and clean-up method. Consequently, it was concluded that both methods (ES 07552.1 and KS I ISO 16703) were not compatible.
