| 摘 要： | 对昆明西郊天然草地植物“五毒”元素含量特征进行了分析，结果显示，受试植物中元素含量的相对离散度铬〉铅〉汞〉砷〉匐，与元素含量的变化顺序不完全吻合。元素铅与是在０．０５水平呈现显著相关性，蓁元素间未达显著相关水平，测试植物与世界草本植物元素呈范围值上限相对照、铬、镉、铅、汞、砷超标百分率（％）分别为：０．２０、５０、５０和９０。

| Abstract: | This paper analyzed the characteristics of harmful element contents in natural herbs in Kunming western suburb. The order of relative dispersion degrees of element contents was Cr>Pb>Hg>As>Cd. Element contents may or may not be directly proportional to relative despersion degree. Only Pb and Cr showed extremely significant correlation, the others did not. Comparing the maximum of world herbs with tested herbs, the excess standard percentages of Cr, Cd, Pb, Hg and As contents in the natural herbs attained 0, 20, 50, 50 and 90 respectively. |
