摘　　要：　用原子荧光光度法和原子吸收分光光度法,测定了西安市郊区蔬菜批发市场及蔬菜生产基地中10种蔬菜80个样品中的汞、砷、铅、铬、镉的含量,并与1996～1997年度的调查结果进行了比较。结果表明,汞、砷、铬、镉的含量较1996～1997年有明显降低,而铅仍是主要的污染元素,有85.0%蔬菜中的铅含量超出国家卫生标准,最高超标8.03倍。The Hg,As,Pb,Cr and Cd contents were determined by atomic abstraction and fluorescence photometer of atom in 80 samples of 10 kinds of vegetables in Xian City.The results shows that Hg,As,Cr and Cd contents in vegetables are lower than that in 1996-1997,and Pd contents are higher than the permitted level of Standard of P.R.C.GB14935-1994 in 85 percent of vegetables as the main pollution element.The highest content of which is 8.05 times of the permitted level of Standard of P.R.C.GB14935-1994.
