摘    要:对重金属铬污染地区的植物吸收与富集重金属的研究表明:(1)铬污染地区植物各部位的Cr含量均超标;(2)铬污染地区植物各部位在不同采样单元中Cr含量基本上是取样点至铬渣堆的距离成反比;(3)铬污染地区各种植物各部位中Cr含量与土壤中Cr含量参考值的比值均在28.76%以上,具有较强的Cr吸收与富集作用,尤其是叶部最高达301.27%,其受铬渣飘尘有较大的影响.

关 键 词:铬渣  污染  富积  植物

Abstract:Collection and absorption of heavy-metals by plants in chromium-pollution area reveal that:(1) the chromium content in various components of the plants exceeds the State Standard;(2) the chromium contents at the identical sampling units are almost inversely proportional to the distance from the chromium rubbish source;(3) The ratio of chromium content in various components of plants to the reference value in soils exceeds 28.76%,especially as high as 301.27% in leaves due to the floating chromium-dust;the r...
Keywords:chromium rubbish  chromium pollution  collection  plants
