本文就三硝基甲苯(TNT)对工人健康的慢性危害进行了综合调查研究。结果表明:1.较低浓度的TNT对工人健康的慢性危害是存在的,尤其对眼晶状体及肝脏的损害更为突出,但对血液方面的影响不大。2.白内障的检出率与空气中TNT的浓度及工龄间存在一定程度的剂量一反应关系。3.肝功异常检出率与空气中TNT浓度亦存在密切相关。4.TNT代谢产物可在一定程度上反映体内TNT的负荷水平。5.控制皮肤污染是预防低浓度TNT’慢性危害的重要措施之一。
This article conducted a comprehensive investigation on the chronic hazards of trinitrotoluene (TNT) to workers’ health. The results showed that: 1. Chronic injury to workers’ health caused by lower concentration of TNT existed, especially for the damage of lens and liver of eyes, but had little effect on blood. 2. The detection rate of cataract and air TNT concentration and length of service there is a certain degree of dose-response relationship. 3. The detection rate of abnormal liver function and TNT concentration in the air also exist closely related. 4.TNT metabolites to a certain extent, reflect the level of TNT in vivo load. 5. Control of skin pollution is one of the important measures to prevent the chronic harm of low concentration of TNT.
