目的了解高原地区低质量浓度2,4,6-三硝基甲苯(TNT)对作业者肝脏及眼晶体的影响,为高原环境因素与TNT交互作用的研究提供基础数据。方法对高原地区某厂采用职业卫生调查,对接触TNT的184名生产工人进行健康检查。结果 2000—2005年被调查工厂的工作场所空气检测TNT质量浓度均值基本符合国家职业卫生标准;肝功能异常检出率接触组高于对照组(17.9%和5.5%,P<0.01);B超肝肿大检出率接触组高于对照组(7.6%和6.3%,P>0.05);眼晶体混浊和白内障检出率接触组(7.6%,4.3%)均高于对照组(1.6%,0%),差异有统计学意义(P<0.05)。结论高原地区长期接触低质量浓度TNT可对作业工人产生慢性职业危害。
Objective To understand the effect of low concentration 2,4,6-trinitrotoluene (TNT) on the liver and ocular lens in high altitude area and provide basic data for the interaction between plateau environmental factors and TNT. Methods Occupational health survey was conducted on a factory in the plateau area to conduct a health checkup on 184 production workers in contact with TNT. Results The mean concentrations of TNT in the workplace air tests from 2000 to 2005 basically met the national occupational health standards. The detection rate of abnormal liver function was higher in the exposure group than in the control group (17.9% vs 5.5%, P <0.01) The detection rate of hepatomegaly in the exposure group was higher than that in the control group (7.6% and 6.3%, P> 0.05). The detection rate of ocular opacity and cataract in the exposure group (7.6%, 4.3% 0%), the difference was statistically significant (P <0.05). Conclusion Long-term exposure to low-level concentrations of TNT in the plateau may cause chronic occupational hazards to workers.
