논 문 : 토양 및 퇴적물 시료 중 다이옥신(PCDD/DFs)의 전처리방법 개선에 관한 연구 = A Study on Improving Pre-treatment Methods for Dioxins (PCDD/DFs) in Soil and Sediment Samples

다국어 초록 (Multilingual Abstract)

This study was carried out to improve pretreatment methods for analyzing polychlorinated dibenzo-p-dioxinsdibenzofurans (PCDD/DFs) in environmental samples such as soils and sediments. The official method of using clean-up standard substances and the method of pre-packed column system analysis were applied to the environmental samples. The recovery rates of these two methods were low. In addition, wide ranges of relative standard deviations (RSD) were observed in highly-chlorinated congeners of sediment samples. In the soil samples, similar PCDD/DFs concentrations were observed for each pretreatment method. The sediment samples, however, showed larger RSDs due to complex matrices and low concentrations. An automated preparation system was also applied as a pretreatment method for analyzing PCDD/DFs in environmental samples. This system was found less affected by the proficiency of analysts than the other pretreatment methods. Besides, the automated preparation system was useful for simple/rapid clean-up, and can reduce the consumption of analysis apparatus as well as organic solvents. The automated preparation system can also be applied to monitoring and screening PCDD/DFs in environmental samples.
