1983年,曾对赣州有色冶金机械厂接锰作业工人进行了职业危害调查。发现发锰值高于本地区正常值,并发现空气锰含量亦较高。为了探索锰偏高的原因,掌握剂量-反应关系,以便为采取相应管理措施提供科学依据。于1985年复又对该厂进行了劳动卫生流行病学调查,结果报告如下。 材料及方法 一 材料 该厂建厂已有近50年历史,现有职工2,000余人。1958年以来,一直生产锰钢产品,近年来,生产运矿车。其原材料中含锰量约占10～13％,锰焊条含锰
In 1983, Ganzhou Non-ferrous Metallurgical Machinery Plant had manganese job workers conducted a survey of occupational hazards. Found that hair value is higher than the normal value of the region, and found that air manganese content is also higher. In order to explore the reason why manganese is too high, dose-response relationship should be mastered in order to provide a scientific basis for adopting corresponding management measures. In 1985, the factory again conducted a survey on labor hygiene epidemiology and the results were reported as follows. Materials and methods of a material The plant has been established nearly 50 years of history, more than 2,000 employees. Since 1958, it has been producing manganese steel products, in recent years, the production of transport cars. The manganese content of its raw materials account for about 10 to 13%, manganese electrode manganese
