接触苯系物对作业人员血象影响的研究

[目的]分析苯系物作业工人血象特征,了解苯系物对作业工人血液系统的危害现状。[方法]使用东亚Xi-1800全自动血细胞分析仪进行血常规检测,比较接触组(接触苯系物)和对照组(非接触苯系物)白细胞、中性粒细胞绝对值、红细胞、血红蛋白和血小板均值以及异常检出率的差异。[结果]苯系物作业工人外周血中性粒细胞绝对值(P<0.01)平均水平较对照组低;白细胞减少、中性粒细胞绝对值偏低检出率高于对照组(P<0.05)。[结论]接触苯系物对人体外周血白细胞、中性粒细胞绝对值等有一定的影响。

Hemocytometry of workers exposed to benzene and analogues

[Objective] The blood examination data of workers exposed to benzene and analogues were analyzed to understandthe adverse effect of benzene exposure on hemocytometry. [ Methods ] The data of 2 620 exposed workers （ male 1142, female 1186） and 2511 control workers （male 1437, female 1 074） were compared. [Results] Compared with reference group without any exposure history to benzene and analogues, the exposed workers had a lower level of leukocytes counting, particularly neutrophilic leukocytes, erythrocyte counting,hemoglobin and blood platelet counting. The number of abnormal workers was significant higher than that in the reference group. [Conclusion] The occupational exposure to benzene and analogues may have adverse effect on hemocytometry under current exposure level and it should be given more attention to.
