宝鸡市麟游县煤矿区周边农田土壤重金属污染安全评价
Safety Evaluation of Heavy Metal Pollution in the Farmland Soils Surrounding the Coal Mines Area in Linyou County of Baoji City
摘要
Abstract
In this paper, Beimafang coal mine, Guojiahe coal mine and Beiwang coal mine in Linyou County were selected as the study regions and field sampling and indoor analysis of the farmland soils surrounding the study regions was performed to determine the pollution status of such seven heavy metals as Zn, Cr, Pb, Cu, Cd, Hg and As. The results showed that the maximal contents of the seven heavy metals all exceeded the soil background values of Shaanxi Provincial level and local level. Evaluation of single factor contaminant index showed that Hg pollution in the surrounding soils was serious and some local area was heavily polluted by Hg. Evaluation of comprehensive contaminant index indicated that these three coal mine regions were in moderate pollution and pollution level of Beiwang coal mine was the highest. Evaluation of geological cumulative index showed that accumulation levels of Hg in the three regions were from moderate pollution to heavy pollution, followed by those of Cd. Therefore, the farmland soils surrounding the study regions were polluted by heavy metals at various degrees and certain measures should be taken by relevant administrations to control the polluted soils in the regions.关键词
