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 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.

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。

Field investigation was carried out to study the effect of long-term sew-age irrigation on formation of nickel in manured loessial soil. The possibili- ty of soil nickel pollution,which was evaluated by the soil nickel fraction, was also discussed.The results showed that the nickel coming from sewage irrigaton was concentrated in tilling hoirizon(0-20cm)of the soil, and did not migrated to the lower horizon.The content of the nickel bound to car-bonates,Fe-Mn oxides or organic matter...

本文采用田间调查的方法研究了长期污灌对土镍形态的影响,探讨了用土壤镍形态作为指标评价土壤镍污染的可能性。结果表明,污灌带入到土壤中的镍聚集在土壤耕层,未向下迁移转化,污灌能明显增加耕层土壤碳酸盐结合态,铁锰氧化物结合态和有机质结合态镍的量,对残渣态镍没有影响。

Objective To study the influence of β-carotene on Ni 2O 3-induced DNA strand breakage of human lung fibroblast cells and to explore the application of single cell gel electrophoresis(SCGE) in detecting genotoxicity.Methods Single cell gel electrophoresis(SCGE) assay or comet assay was used to study the effects of β-carotene on Ni 2O 3-induced DNA strand breakage of human lung fibroblast cells.Results Ni 2O 3 could induce DNA double strand breakage in human lung fibroblasts cells as compared with the control group(P<0.01),and the damage ratio clould descend singnificantly by using β-carotene and Ni 2O 3 in human lung fibroblast cells as compared with that of the Ni 2O 3 group(P<0.01).Conclusion The doublestrand DNA breakage of human lung fibroblast cells can be induced by Ni 2O 3.β-carotene can degrade observably the DNA double strand breakage induced by Ni 2O 3.SCGE assay is a simple,convenient,rapid,sensitive and economic method in detecting genotoxicity.It can be applied to all levels of monitoring and studing environmental pollution and human diseases(Nickel pollution).

目的 探讨β 胡萝卜素对氧化镍致人肺成纤维细胞DNA损伤作用的影响。方法 应用单细胞凝胶电泳技术 (singlecellgelelectrophoresis,SCGE)或称彗星电泳技术 (cometassay)比较研究。 结果 氧化镍 (Ni2 O3 )可引起人肺成纤维细胞DNA双链断裂损伤 ,Ni2 O3 与β 胡萝卜素共同处理的人肺成纤维细胞的DNA双链损伤较之Ni2 O3 单独处理组降低 (P <0 .0 1)。结论 氧化镍可引起人肺成纤维细胞DNA双链损伤。β 胡萝卜素可明显降低Ni2 O3 对人肺成纤维细胞DNA链的损伤作用。SCGE是一种简便、快速、敏感及经济的细胞基因毒性检测方法 ,可应用于各级水平的环境与人类疾病 (镍污染 )检测与研究。
