【摘要】 [目的]了解某化工厂三硝基甲苯(TNT)的职业危害情况。[方法]采用劳动卫生学调查方法。[结果]车间空气中TNT浓度波动在1mg/m~3上下。93名作业工人肝、脾肿大分别为23.7％和10.8％,均高于对照组;眼晶状体检查,晶体受损率达83.9％;血细胞计数的均值与对照组差异均无显著性;乙肝表面抗原>1:16者21.5％,高于对照组。诊断轻度中毒13名,重度中毒8名,中毒与接触工龄密切相关,各工种之间差异无显著性。[结论]加强对工人的卫生知识宣传,减少皮肤污染非常必要;对TNT中毒性肝炎敏感特异指标的研究,对保护TNT接触工人的眼睛的研究应该重视。更多还原

【Abstract】 [Purpose]To understand the situation of occupational damages by TNT in a certain chemical factory. [Method]To adopt labor hygiene investigation method . [Result]TNT density in the air is at about Img/m3 in the workshop. The level of hepatomegalia of the tested 93 workers is 23. 7% and splenomegalia 10. 8% , both of the two figures are higher than those of contrastive group. According to the crystalline lens examination, the crystalline lens are damaged by 83 .9% .No significant difference is found in cytometry compared with the contrastive group. Those tested workers whose HBsAg. 1:16 are of 21.5% which is higher than those of contrastive group. As related with working time, but not with the sorts of work. [Conclusion]It is vital to propagate hygienic knowledge to the workers in order to reduce the chance of dermal infection. Emphasis should be put on the study on hepatitis sensitive specificity index caused by TNT poison and on methods to protect workers eyes.更多还原
