有关锰对神经等系统的研究已有很多报道但锰对血液系统影响的文献很少,且各说不一。我们对长期从事锰作业工人的末稍血液进行了检查,现将结果报告如下。观察对象为沈阳某电焊条厂某车间含锰电焊条制造工81名(男23名、女58名),年龄21～58岁,平均32.4岁;接锰工龄3～33年,平均12.4年。车间空气锰平均浓度为0.758mg/m~3,超过国家卫生标准(0.2mg/m~3)。但按“慢性锰中毒诊断标准”未发现锰中毒者。对照组为沈阳某机械厂,非接触锰和其它毒物的
There have been many reports on the research of manganese and other nervous systems, but there is little literature on the influence of manganese on the blood system, and they are different. We examined the last minute blood of manganese workers and reported the results as follows. Observe the object of a factory in Shenyang, a welding electrode containing manganese manufacturing workers 81 (23 males and 58 females), aged 21 to 58 years, an average of 32.4 years of age; received manganese service for 3 to 33 years, an average of 12.4 years. The average concentration of air manganese in the workshop was 0.758mg / m ~ 3, exceeding the national health standard (0.2mg / m ~ 3). However, according to the “diagnostic criteria of chronic manganese poisoning” found no manganese poisoning. The control group was Shenyang Machinery Factory, non-contact manganese and other poisonous substances
