某化工企业接触二氯乙烷作业人员健康状况调查

Investigation on Health Status of Workers Exposed to Dichloroethane in a Chemical Plant

目的探讨长期接触二氯乙烷对工人健康的影响。方法对某市化工企业接触二氯乙烷240名工人(观察组)的健康状况进行分析,同时选择同单位无二氯乙烷接触史220名工人进行对照分析。结果观察组神经衰弱症状检出率明显高于对照组(P<0.01),并随着工龄增加而增高;肝功能异常检出率观察组为17.50%,对照组为7.73%,2组差异有统计学意义(χ2=9.80,P<0.01),且观察组肝功能异常率与工龄长短有关。结论长期接触二氯乙烷可对工人神经系统和肝功能造成一定程度的损害。

[Objective]To explore the effect of long-term exposed to dichloroethane on health of workers.[Methods]The health status of 240 workers exposed to dichloroethane（the observation group） in a chemical plant was analyzed,and 220 workers without contact history in the same plant were selected as the control group.[Results]The detection rate of neurasthenia in the observation group was higher than that in the control group significantly（P〈0.01）,and it increased with working ages.The detection rate of abnormal liver function in the observation group and the control group was 17.50% and 7.73% respectively,the difference between two groups was significant（χ2=9.80,P〈0.01）,and the abnormal rate of liver function in the observation group was related to working ages.[Conclusion]Long-term exposed to dichloroethane may cause damage to nervous system and liver function of workers.
