目的调查引起一起疑似职业性急性1,2-二氯乙烷中毒事故的原因。方法调查1名疑似职业性1,2-二氯乙烷中毒病人所在公司的各项职业卫生管理体制、生产作业场所中有害物质浓度和同车间接触人员的职业健康检查情况。结果用人单位未建立职业卫生管理规章制度;鞋操作位空气中1,2-二氯乙烷浓度CTMA为32.9mg/m3、CSTEL为36.3mg/m3,分别超限3.7和1.6倍;被检的29名底部车间工人中,有19名工人尿中β2-微球蛋白≥1.2μg/ml,异常率为65.5%;自诉症状头晕、头痛、烦燥、恶心、呕吐等15人,异常率为51.7%。结论该次事件中鞋岗位使用的散装港宝水、309黄胶中含高浓度1,2-二氯乙烷,鞋岗位空气中1,2-二氯乙烷浓度超过国家卫生限值规定,结合临床表现,可以确认该起事件为疑似职业性急性1,2-二氯乙烷中毒事件。
[ Objective ] To investigate the causes of an suspected incident of acute occupational poisoning induced by 1,2- dichloroethane.

[ Results ] The employing unit had not established occupational health management rules and regulations ; In the shoemaking operation post, air 1,2-dichloroethane density CTWA was 32.9 mg/m^3 , CSTEL was 36.3 mg/m^3 , beyond the limit 3.7 times and 1.6 times respectively; of 29 workers in base workshop, 19 workers＇urine β2 MG ≥ 1.2ug/ml, the abnormal rate was 65.5% ; 15 people had private prosecution symptoms of dizziness dizziness, headache, headache, dysthesia, nausea, vomiting and so on, the rate of abnormality was 51.7%. [ Conclusion] In this incident, viscose and 309 yellow gum, which are used in the shoemaking post includes highly concentrated 1,2-dichloroethane, and air 1,2-dichloroethane densities surpasses the national health limit value, combined with the clinical manifestation, this event can be confirmed as the suspected incident of acute occupational poisoning induced by 1,2- dichloroethane.
