目的为探讨ＴＮＴ接触对神经行为功能影响。方法采用ＷＨＯ神经行为核心测试组合（ＮＣＴＢ）并结合因子分析方法研究ＴＮＴ接触对神经行为功能的影响。ＴＮＴ接触工人共５９名，平均尿ＤＮＡＴ浓度为２７７ｍｇ／Ｌ，对照工人共５３名，平均尿ＤＮＡＴ浓度为０６３ｍｇ／Ｌ。结果ＴＮＴ接触对工人的记忆力及心理运动有影响，尿ＤＮＡＴ水平与第三因子得分存在剂量－反应关系。结论提示ＴＮＴ对心理运动稳定度的影响有特异性。
Objective To investigate the effect of TNT exposure on neurobehavioral function. Methods The WHO Neurobehaviour Core Test Set (NCTB) combined with factor analysis was used to investigate the effect of TNT exposure on neurobehavioral function. The total number of TNT exposed workers was 59, with an average urinary DNAT concentration of 277mg / L and a total of 53 control workers with an average urinary DNAT concentration of 063mg / L. Results TNT exposure affected the memory and psychomotor of workers, and there was a dose-response relationship between urinary DNAT level and third-factor score. Conclusions suggest that TNT has specific effects on the stability of psychomotor.
