磷矿周围环境镉污染情况调查研究

Investigate of Cadmium Pollution in Surrounding Environment of the Phosphate Mine

为掌握磷矿区周围镉污染情况,确保畜禽养殖生产安全,采用电感耦合等离子体质谱法对矿区周围环境中的水源、土壤、饲草和畜禽体内的镉污染程度展开调查。结果:矿区环境中土壤、地表水镉含量均超标;畜禽中牛肾脏、牛肠、牛肺脏、羊脾脏、羊肌肉镉含量超标。结论:磷矿周围环境以及饲养的牲畜存在较严重的镉污染,从公共卫生学角度应给予高度关注。

The phosphate surroundings and livestock cadmium pollution survey of Guizhou, phosphate surroundings cadmium pollution control to evi- dence. Methods ： all samples were determined with method of atonmic fluorescence absorption spectrometry. Results ： （ 1 ） The content of cadmium of soil and water is exceed the standard in the phosphate mine environment. （ 2 ） The levels of cadmium in the livestock is exceed the standard such as cattle kid- ney, cattle intestines, sheep lung, sheep spleen and sheep muscle. Conclusions： the results indicated that the serious cadmium pollution is existed in livestock around the phosphate mine .
