【摘要】 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。更多还原

【Abstract】 The present situation of nickel pollution in the surrounding environment of a nichel mine and its smeltery was investigated. The nickel content of the samples was determined with colorimetry of dimethylglyoxime and an analysis of contrast was also made. The results showed that the nickel content in air, soil, vegetables and grains in downtuyere area is higher than that of corresponding samples in uptuyere area. The nickel concentration in the river near the plant is higher than that of the upper reaches. The nickel level in the hair of smeltery workers is higher than that of peasants living in uptuyere area. All differences above mentioned are remarkable.更多还原
