一起慢性正已烷中毒事故调查分析

Analysis of a Chronic N-Hexane Poisoning Accidence in Printing Workers

目的 :检测某印刷公司接触正已烷作业工人生产环境与职业性慢性正已烷中毒的发病状况。方法测定某印刷公司生产环境空气正已烷浓度 ,对接触正已烷工人进行神经系统检查 ,神经肌电图检查和尿 2 ,5 已二酮测定。结果 :车间空气正已烷平均浓度 30 2 .4 6mg/m3 ,工人平均年龄 2 4 .6岁 ,接毒工龄平均 3.4年 ,诊断为职业性慢性正已烷中毒 16例。结论 :长期接触空气浓度超标正已烷 。

Objective: To explore the prevalence of occupational chronic n hexane poisoning and its environmental exposure level among printing workers.Methods:The workplace air concentration of n hexane was measured and neurological examination,neuro myography tests and urinary 2,5 pentadione content measurement of exposed workers were performed. Results: Workplace averaged air concentration of n hexane was 302.46 mg/m 3;the averaged age of the exposed workers was 24.6 years; the averaged exposed working year was 3.4 years.Sixteen workors among them were diagnosed as chronic n hexane poisoning.Conclusion:Long term exposure to the over standard n hexane air concentration without reasonable protection would elicit occupationd poisoning in part of the exposed workers.
