摘　　要：目的了解珠宝加工企业生产过程中苯作业环境对工人健康的危害以及实行干预措施后的效果。方法对企业作业环境空气中苯系物浓度进行检测,对工人进行职业健康检查,并实施了干预措施。结果作业场所空气中苯浓度干预前合格率为20%,干预后为100%;作业工人的自觉症状和体征(头痛、头昏、失眠、食欲减退、皮肤损害、出血倾向等)在干预后有不同程度的改善,在干预前女工月经异常(经期延长、经量增多和周期紊乱)的情况干预后也得到改善。作业工人血常规检查方面,干预前工人WBC、Hb和PLT下降的发生率均明显高于干预后。干预前后的检查结果差异有统计学意义。结论对珠宝加工企业实施干预措施后,作业场所空气中苯浓度下降至容许范围内,工人健康情况比干预前得到明显改善。[ Objective ] To investigate the health hazards of benzene-exposed environment in the jewelry processing enterprises, study the effects of intervention measure. [ Methods] The benzene series concentration in the working environment air was detected, occupational health examination was carried out in workers, and intervention measures were performed. [ Results]The qualified rate of the benzene series concentration in the working environment air was 20% and 100% before and after intervention respectively. Af- ter intervention, the subjective symptoms and signs of workers （ headache, dizziness, insomnia, poor appetite, skin lesions and hem- orrhagic tendency） improved in different degree. The abnormal menstruation of female workers （menostaxis, menorrhagia and irregu- lar menstrual periods） improved after intervention as well. In terms of blood routine examination, the incidences of the WBC, Hb and PLT decreases before intervention were higher than those after intervention. The difference in examination results between before and after intervention was significant. [ Conclusion] After the intervention measures were implemented in the jewelry processing en- terprises, the benzene series concentration decreased into the allowable range, and the health conditions of workers improved greatly.
