摘要
在湖南省有色金属矿区采集植物样品和土壤样品各112份,在实验室分析了土壤和植物样品中镉的含量。研究结果表明:采样区土壤镉污染严重,104个土壤样品的镉含量均超过了1mg/kg;5种植物对镉的转运系数大于2,分别是鬼针草、糯米团、马兰、龙葵、艾蒿,其中马兰对镉的转运系数最高为4.29。
112 plant and soil sample were collected from Hunan nonferrous metals mining, and analyzed the cadmium content in the soil and plant.The results showed that： Soil cadmium pollution was serious at sampling area, cadmium content of 104 samples were more than lmg/kg. There were five species＇ Cd transport coefficient greater than 2, respectively, sticktight, angiospermae, herba kalimeridis, Solanum nigrum L, artemisiae argyi, which herba kalimeridis＇s cadmium transport eoeffieiented up to 4.29.
