【摘要】：在小秦嶺金礦區(qū)內(nèi)選取姚青村、來福溝和毛溝三個(gè)具有代表性研究區(qū),采集研究區(qū)內(nèi)尾渣堆及渣堆周圍農(nóng)田樣品30個(gè),測(cè)定了重金屬Cr、Ni、Cu、Cd、Zn、As、Pb含量。對(duì)土壤樣品重金屬測(cè)定結(jié)果分別采用地累積污染指數(shù)法和潛在生態(tài)危害指數(shù)評(píng)價(jià)法進(jìn)行評(píng)價(jià),結(jié)果顯示:As不是礦業(yè)活動(dòng)污染的典型金屬;姚青村和來福溝重金屬典型污染物為Cu、Zn、Cd、Pb。采用地累積污染指數(shù)法評(píng)價(jià),姚青村和來福溝的Pb屬于極嚴(yán)重污染,而Cr、Ni均屬無污染。采用潛在生態(tài)危害指數(shù)法進(jìn)行評(píng)價(jià),毛溝研究區(qū)屬輕微生態(tài)危害,姚青村和來福溝生態(tài)風(fēng)險(xiǎn)程度均屬極強(qiáng),貢獻(xiàn)率大的元素主要為Pb和Cd。
[Abstract]:Selection in small gold mine area of Qinling Mountains Yao Qing Cun, Fu Mao Gou and Gousan representative of the study area, collected in the study area of tailings heap and heap farmland around 30 samples, the determination of heavy metals of Cr, Ni, Cu, Cd, Zn, As, Pb content of soil samples. The results were used in the determination of heavy metals the accumulation of pollution index and potential ecological risk index evaluation method. The results show that As is not a typical metal mining pollution; typical pollutants and heavy metals for Yao Qing Fu Gou Cu, Zn, Cd, Pb. by the accumulation of pollution index, and the Pb Fu gou Yao Qing Cun are extremely serious pollution, and Cr, Ni are no pollution. The potential ecological risk index method to evaluate the Maogou study belonged to slight ecological harm, Yao Qing Cun and live ditch ecological risk degree are very strong, the contribution rate of the main elements are Pb and Cd.
