摘要
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.
