目的了解茂名市某钓鱼竿厂苯、甲苯、二甲苯("三苯")对作业人员健康的危害程度.方法对茂名市某钓鱼竿厂工作场所进行"三苯"浓度测定,并对50例"三苯"作业工人(接触组)和68例不接触"三苯"工人(对照组)进行体检.结果该厂工作场所空气中的苯、甲苯、二甲苯时间加权平均容许浓度(PC-TWA)、短时间接触容许浓度(STEL)均未超标.接触组头痛、头晕、失眠、记忆力减退的发生率高于对照组,差异有显著性(P<0.05或P<0.01).血常规检查结果显示,接触组白细胞减少的检出率高于对照组(P<0.01).结论该厂"三苯"对作业工人的健康存在一定的潜在危害,应做好"三苯"危害的预防工作.

Objective To study the hazardous effect of mixed benzene(benzene,toluene and xylene,BTX)on the health of the workers in a fish pole plant in Maoming Guangdong.Methods The concentrations of BTX in the workplaces were determined in a fish pole plant in maoming and 50 workers exposed to BTX(exposure group)and 68 unexposed workers(female 35cases,men 31 cases,(control group)were health examinationed.Results The PC-TWA and the STEL of BTX in the workplaces were lower occupation exposure limits.The incidences of headache、dizzy、wakefulness、mnemasthenia in the exposure group were significantly higher than those in the control group(P<0.05 or P<0.01).The results of the blood test show that the reduce of the white blood cell of the exposure group(6 cases)were significantly higher than those in the control group(1 cases)(P<0.01).Conclusion It may lead to potential hazard on the exposure BTX in the fish pole plant,so protection against it should be made.
