对某镍矿冶炼厂周围环境镍污染现状进行了调查研究。采集大气、水、土壤、蔬菜、粮食和头发等样品,用丁二酮肟比色法测定了镍的含量。分析结果表明,下风向大气、土壤,蔬菜、粮食样品中镍含量皆高于上风向对应样品中的镍含量;厂区河水镍含量高于上游河水的镍含量;冶炼工人发镍高于居住上风向区域农民发镍。并且皆存在着显著性差异。
The nickel pollution in the environment around a nickel ore smelter was investigated. Samples of the atmosphere, water, soil, vegetables, grains and hair were collected and the nickel content determined by the dimethylglyoxime colorimetric method. The results showed that the contents of nickel in the downwind air, soil, vegetables and grain samples were all higher than those in the upwind samples. The nickel content in the river water was higher than that in the upstream river. The nickel content of smelting workers was higher than that in residential areas Regional farmers made nickel. And there are significant differences.
