目的研究三硝基甲苯(TNT)对作业人员血液系统的影响,为开展职业危害的防护提供依据。方法对219名TNT作业人员进行血常规检查,并与对照组进行比较。结果 TNT组白细胞系异常发生率为53.9%,对照组为41.3%,两组差异有统计学意义(P<0.05);红细胞系和血小板组间差异无统计学意义(P>0.05)。结论 TNT可使作业人员的白细胞系发生异常。 Objective To study the effect of trinitrotoluene (TNT) on the blood system of workers and provide the basis for the protection of occupational hazards. Methods A total of 219 TNT workers were examined by blood routine and compared with the control group. Results The abnormal incidence of leukocyte in TNT group was 53.9% and in control group was 41.3%, there was significant difference between the two groups (P <0.05). There was no significant difference between erythrocyte and platelet group (P> 0.05). Conclusion TNT can make the operator of abnormal white blood cell line.
