钒冶炼厂周边陆生植物对重金属的富集特征
Phytoaccumulation of heavy metals by terrestrial plants around vanadium smelters
摘要
Abstract
Twenty-nine species samples of higher plants which belong to twenty families and seven soil samples were collected from a vanadium smelter. The contents of heavy metals in the native plants and soil were analyzed by ICP-MS and ICP-OES. The re-sults show that the soil of the smelting plant area has general Cr, Cd and V pollution phenomena;moreover, V and Cr pollution is con-spicuous. V, Cr, Cd and Pb are detected from all these collected polluted higher plants, and the content of V is the highest. Pteris vittata L, the native plant, has the highest V content;the accumulation amounts of the aboveground part and the underground part are 86. 51 mg·kg-1 and 814. 25 mg·kg-1 , respectively. The enrichment and transport capacity of Daucus carota L is obviously higher than that of other plants;the accumulation amounts of the aboveground part and the underground part are 18. 56 mg·kg-1 and 5. 66 mg· kg-1 , respectively. These two kinds of plants show high tolerance to heavy metal pollution in the vanadium smelting plant area, and they can be used as pioneer species of pollution remediation.关键词
