十种稀特蔬菜对硝酸盐和重金属元素的富集能力
Accumulation Ability of Ten Kinds of Special Rare Vegetables to Nitrate and Heavy Metal
摘要
Abstract
Taking 10 kinds of special rare vegetables as research objects, the contents of nitrate and 5 kinds of heavy metals ( Pb, Cd, As, Hg and Cr) in the edible parts were determined, and the pollution and health risk assessment were also conducted.The results showed that different special rare vegetables had dif-ferent accumulation abilities to nitrate.Among them, the nitrate contents of Amaranthus tricolor, Amaranthus viridis,Mentha haplocalyx, Taraxacum mongolicum, Dendranthema indicum, Sedum aizoon and Tragopogon porrifolius reached high pollution level.The order of accumulation ability of special rare vegetables to heavy metals was Pb>Cr>As>Cd>Hg.Amaranthus tricolor and Amaranthus viridis were mildly polluted by heavy metals.The exposed risk indexes of special rare vegetables to heavy metals were all less than 1 , so the con-sumption of special vegetables would not cause health risk.关键词
