为了解社队办电镀行业中铬的危害,我们于1981年10月,对20个电镀厂进行了劳动卫生学调查,并对115名镀铬工人进行了健康检查。结果报告如下。 现场情况 20个电镀厂的镀铬缸都设有槽边吸风和铬酸雾净化回收装置,槽口控制风速分别为0.4—2米/秒,其中0.5米/秒的占85％。铬酸雾浓度在20个样品中只有2个超过国家卫生标准,分别为0.1615和0.1692毫克/立方米,其余均在0.05毫克/立方米以下。 体检结果 受检的115名镀铬工人中,男性为65人,女性为50人,年龄最小16岁,最大45岁,工龄最短两个月,最长8年,平均工龄为3.8年。
In order to understand the dangers of chrome in the electroplating industry by the communes and brigades, in October 1981, we conducted a survey on hygiene in 20 electroplating factories and performed health checks on 115 chrome-plated workers. The results are reported below. Site conditions 20 electroplating chrome plating tanks are equipped with slot suction and chromate mist purification recovery device, notch control wind speed of 0.4-2 m / s, of which 0.5 m / s accounted for 85%. Chromic acid mist concentration in only 20 of 20 samples over the national health standards, respectively, 0.1615 and 0.1692 mg / cubic meters, the rest were below 0.05 mg / cubic meters. Out of a total of 115 chrome-plated workers examined, the number of males was 65 and that of females was 50, the youngest being 16 and the youngest being 45. The minimum length of service was two months and the maximum was eight years. The average length of service was 3.8 years.
