用慧星检测技术即碱性单细胞凝胶（ｔｈｅａｌｋａｌｉｎｅｓｉｎｇｌｅｃｅｌｌｇｅｌ，ＳＣＧ）检测术检测１１５名苯作业工人外周血淋巴细胞ＤＮＡ损伤情况。作业工人分为苯中毒组、高浓度接触组、低浓度接触组和对照组（不接触苯的工人）。结果表明：苯中毒组ＤＮＡ损伤率明显高于对照组，而高浓度接触组和低浓度接触组与对照组无显著性差异。说明长期接触高浓度苯的敏感工人ＤＮＡ损伤明显。ＤＮＡ损伤与苯致白血病的发生发展是否有关，有待进一步研究。
The damage of DNA in peripheral blood lymphocytes of 115 benzene-exposed workers was detected by comet assay (thealkalinesinglecellgel, SCG). Workers were divided into benzene poisoning group, high-concentration exposure group, low-concentration exposure group and control group (workers without exposure to benzene). The results showed that DNA damage rate in benzene poisoning group was significantly higher than that in control group, but no significant difference between high concentration exposure group and low concentration exposure group and control group. Indicating that long-term exposure to high concentrations of benzene sensitive workers DNA damage significantly. DNA damage and the occurrence and development of benzene-related leukemia is relevant, pending further study.
