| 摘 要： | 对陕西省大中城市郊区菜园14类152份蔬菜样品中12种矿质营养元素和5种重金属元素含量分析结果表明：12种矿质营养元素含量水平为钾＞钙＞钠＞磷＞镁＞铁＞锰＞锶＞锌＞硼＞钡＞铜，各元素含量在不同地区间有较大差异;5种重金属污染在元素在不同地区有含量超标现象，特别是铅含量超标严重，原因是采用污水灌溉及公路 干线汽车尾气造成的污染。

| Abstract: | 12 kinds of mineral elements(K, Na, Ca,Mg, Cu, Fe,Mn, Zn, Sr, Ba, P, B) and 5 kinds of heavy metal elements (As, Hg, Pb, Cr, Cd) in 152 samples of 14 kinds of vegetables sampled six big cities in Shaanxi Province were measured.The result showed that there were difference in distribution and content of the mineral elements and heavy metals among various vegetables and differen tregions in Shaanxi, and the pollution condition and causes of heavy metals of vegetables in different regions in Shaanxi province were realized. |
