Of a total of 528,729 workers exposed to benzene or benzene mixtures in China, 508,818 (96.23%) were examined. Altogether 2,676 cases of benzene poisoning were found, a prevalence of 0.15%. A higher prevalence of benzene poisoning was found in the cities of Hangjou, Hefei, Nanjing, Shenyang, and Xian. The geometric mean concentration of benzene in 50,255 workplaces was 18.1 mg/m3 but 64.6% of the workplaces had less than 40 mg/m3. There was a positive correlation between the prevalence of benzene poisoning and the concentration in shoemaking factories. The prevalence of benzene induced aplastic anaemia in shoemakers was about 5.8 times that occurring in the general population. The results of this investigation show the need for a practicable hygiene standard to prevent benzene poisoning.
在中国,共有528,729名接触苯或苯混合物的工人接受了检查,其中508,818人(96.23%)接受了检查。共发现2676例苯中毒病例,患病率为0.15%。在杭州、合肥、南京、沈阳和西安等城市发现苯中毒患病率较高。50255个工作场所苯的几何平均浓度为18.1毫克/立方米,但64.6%的工作场所浓度低于40毫克/立方米。制鞋工厂中苯中毒患病率与浓度呈正相关。鞋匠中苯所致再生障碍性贫血的患病率约为一般人群的5.8倍。本次调查结果表明需要制定切实可行的卫生标准以预防苯中毒。
