1983～1986年对某厂镍冶炼作业劳动卫生条件和工人健康状况进行了调查。近年粉尘浓度在降低。作业地点空气镍平均浓度波动在0.0095mg/m~3～1.7331m g/m~3,82.56％的样品浓度低于0.5mg/m~3。熔化工序空气中Co、Cd、Cu、Zn、Pb及As浓度很低或低于MAC;但二氧化硫、氯化氢及硫酸雾浓度较高,有些样品浓度超过国家标准。对428名接镍工人和111名机械加工工人(对照)进行了健康检查。除尿镍增高外,检出的临床所见不能完全归因于接触镍。从现场资料分析,车间空气中镍及其无机化合物的最高容许浓度可考虑订为0.5mg/m~3。
From 1983 to 1986, the sanitary condition of workers in a nickel smelting operation in a factory and the workers’ health status were investigated. In recent years, the concentration of dust is decreasing. The average concentration of air in the workplace fluctuated between 0.0095mg / m ~ 3 ~ 1.7331m g / m ~ 3 and 82.56%, with the concentration of less than 0.5mg / m ~ 3. The concentrations of Co, Cd, Cu, Zn, Pb and As in the air during the melting process are very low or below MAC. However, the concentration of sulfur dioxide, hydrogen chloride and sulfuric acid mist is higher and some samples exceed the national standards. A total of 428 nickel-plated workers and 111 mechanical workers (control) underwent a medical examination. In addition to urinary nickel increased, the clinical findings were not completely attributable to nickel exposure. According to field data analysis, the maximum permissible concentration of nickel and its inorganic compounds in the air of workshop can be considered as 0.5mg / m ~ 3.
