【摘要】 目的:了解三硝基甲苯(TNT)作业人员眼部的损害情况。方法:对某炸药厂作业人员542人进行体检,重点检查眼睛(视力、B超、散光度和浑浊度),对结果进行统计学分析。结果:检出TNT白内障Ⅲ期患者1人,Ⅱ期17人,I期72人,患病率16.6%,男性高于女性;患病率与年龄、直接接触TNT程度以及工龄呈正相关。结论:加强TNT作业的工艺改革,同时强调个人防护,预防职业性白内障及慢性中毒的发生。更多还原

【Abstract】 Objective:To analyze the influence of trinitrotoluene(TNT) on workers’eyes.Methods:Ocular examinations (which include optometry,type-B ultrasonic,astigmatism and turbidity) are carried on among 542 people who work with TNT,and the results are statistically analyzed.Results:1 person is diagnosed with 3rd stage cataract,17 with 2nd stage,and 72 with 1st,which proves a prevalence rate of 16.6%,and a higher rate for male than female (p<0.05).The prevalence rate is in proportion to age,degree of direct contact to TNT,and length of service.Conclusion:To adopt reformed technology,better aeration,and temperature control to reduce the density of TNT in the air,in order to prevent occupational cataract.更多还原
