目的 探讨三硝基甲苯 (TNT)作业工人晶体损害与尿 2 ,6 二硝基 4 氨基甲苯(DNAT)含量的关系。方法 作业工人散瞳后检查眼晶体 ,并且测定班后尿DNAT含量。结果 当作业工人晶体出现混浊时 ,尿中DNAT含量明显增加 (2 .38mg/L) ,其与接触TNT尚未出现晶体混浊组 (1.44mg/L)比较 ,差异有显著性 (P <0 .0 5 )。结论 晶体混浊程度随尿DNAT含量的增高呈增加的趋势。ILO提出的DNAT 30mg/L生物阈限值不适合我国职业人群。
Objective To investigate the relationship between crystal damage and urinary 2, 6 dinitrotetraaminotoluene (DNAT) content in workers with trinitrotoluene (TNT). Methods Workers dilated eye examination eye crystal, and determination of urine DNAT content. Results When the ophthalmics of workers exposed to opacity, the DNAT content in urine increased significantly (2.38mg / L), which was not significantly different from that of the group exposed to TNT (1.44mg / L) (P <0. 0 5). Conclusion The degree of lens opacity increases with the increase of urinary DNAT content. ILO proposed DNAT 30mg / L biological threshold is not suitable for our occupational population.
