    摘要: Ethylene oxide (EtO) is classified as a known human carcinogen. The formation of EtO-DNA adducts is considered as an important early event in the EtO carcinogenic process. An isotope-dilution on-line solid-phase extraction and liquid chromatography coupled with tandem mass spectrometry method was then developed to analyze one of the EtO-DNA adducts, N7-(2-hydroxyethyl)guanine (N7-HEG), in urine of 46 nonsmokers with excellent accuracy, sensitivity and specificity. The merits of this method include small sample volume (only 120 mu L urine required), automated sample cleanup, and short total run time (12 minutes per sample). This method demonstrates its high-throughput capacity for future molecular epidemiology studies on the potential health effects resulting from the low-dose EtO exposure.
