泰兴市某苯乙烯生产企业工人健康状况调查

Investigation on health status of workers in a styrene production enterprise of Taixing City

目的探讨长期接触苯乙烯对工人健康造成的慢性影响。方法选择某苯乙烯生产企业接触苯乙烯作业工人160人,另选择无接触史的对照组110人,进行职业健康调查分析。结果苯乙烯作业工人神经衰弱症状的检出率、咽喉痛、皮肤异常反应高于对照组,差异均有统计学意义(均P<0.05)。血常规和肝肾功能各项指标观察组与对照组相比较,差异均无统计学意义(均P>0.05);血脂代谢指标中除高密度脂蛋白胆固醇(HDL-C)降低百分率高于对照组外(P<0.05),其余指标异常率差异无统计学意义(P>0.05)。2组工人心电图各种异常率比较,窦性心律失常和ST-T改变差异有统计学意义(P<0.05),束支传导阻滞、低电压和左室高电压差异无统计学意义(P>0.05)。结论长期接触苯乙烯可对工人呼吸系统、神经系统、血脂代谢及心血管系统造成一定程度的损害。

[Objective]To explore the chronic effects of long-term styrene exposure on workers’ health.[Methods]160 styreneexposed workers and 110 workers without contact history in a styrene production enterprise were collected for an occupational health investigation.[Results]The detection rate of neurasthenia,and the rate of sore throat and skin abnormal reaction in exposure group were higher than those in control group,and the differences were statistically significant(all P<0.05). There were no statistically significant differences in indexes of blood routine test and liver and kidney function between the two groups(all P>0.05).For the indicators of lipid metabolism,the percentage of high density lipoprotein cholesterol(HDL-C) decrease in exposure group was higher than that in control group(P<0.05),and there were no statistically significant differences in other indicators(P>0.05).In ECG examination,the differences in sinus arrhythmia and ST-T change were statistically significant between the two groups(P<0.05),and there were no statistically significant differences in bundle branch block,low voltage and left ventricular high voltage(P>0.05).[Conclusion]Long-term styrene exposure can cause damage of the respiratory system,nervous system,blood lipid metabolism and cardiovascular system in workers.
