对河南某化工厂三硝基甲苯（ＴＮＴ）作业工人劳动卫生学调查结果发现，车间空气中ＴＮＴ浓度多数均超过国家最高容许浓度（ＭＡＣ＝１ｍｇ／ｍ３），工人皮肤污染较严重。超氧化物歧化酶（ＳＯＤ）活性测定结果表明，ＴＮＴ接触组和ＨＢｓＡｇ阳性者均高于对照组，推测ＴＮＴ和ＨＢＶ诱发肝损伤机理可能部分归因于活性氧生成。
A survey of labor hygiene of TNT workers in a chemical plant in Henan Province found that most of the TNT concentrations in the air of the workshop exceeded the national maximum allowable concentration (MAC = 1 mg / m3) and workers’ skin was more polluted. The results of superoxide dismutase (SOD) activity assay showed that TNT exposure group and HBsAg positive group were higher than that of the control group. It is speculated that TNT and HBV induced liver injury mechanism may be attributed partly to reactive oxygen species generation.
