摘要
对某镍业公司车间空气中镍浓度和工人指甲镍含量进行了测定。按照生产过程和卫生学特点,将所获数据划分为碎矿压球、电炉转炉和汽车维修三组。空气镍浓度几何均值分别为0.0978、0.0623和0.0202mg/m^3;工人指甲镍几何均值分别为23.04、21.07和4.84μg/g;两者呈现一定的接触水平-反应关系。表明以指甲镍作为职业性接镍人群的生物监测指标有一定的参考价值。
The determination of nickel concentration in the air of workerplaces and the measurement of nickel content in workers' finger nails were carried out in a nickel smeltery.According to the hygienic characteristics and production process the samples were divided into three groups; ore comminution-mould pressing, electric furnace-converter, and auto-repairing.The geometric means of air nickel in these groups were 0.0978, 0.0623 and 0.0202 mg/m3 respectively; the geometric means of nickel content in workers' finger nails were 23.04, 21.07 and 4.84μg/g respectively.Results showed that a certain exposure-response relationship appeared between the contents in the air and those in nails. Therefore, the nickel content in finger nails might be valuable, to be used as an index for biological monitoring in occupational environment.
