| 摘 要： | 主要介绍贵州省贵阳市0~20 cm表层土壤中我国《土壤环境质量标准》中规定含量的8种重金属环境污染元素(汞、镉、铅、铬、砷、锌、铜、镍)含量之间的相关性分析。本文得出达到极相关显著水平(P<0.01)的元素对有:As—Pb、Cd—Cr、N i—Cd、Cu—Cr、Cr—N i、Cr—Zn、Cu—N i、Cu—Pb、Cu—Zn、N i—Zn、Pb—Zn,达到相关显著水平(P<0.05)的元素对有:As—Zn、Cd—Hg、Cd—Zn、Pb—N i。并对相关原因作简单分析。

| Abstract: | This paper introduced the analysis of correlation of elements of heavy metal contamination(Hg,Cd,Pb,Cr,As,Zn,Cu and Ni) that were defined by Environmental Quality Standards for Soils(GB15618-1995).The pair-elements that reach prefect correlation(P < 0.01) As—Pb,Cd—Cr,Ni—Cd,Cu—Cr,Cr—Ni,Cr—Zn,Cu—Ni,Cu—Pb,Cu—Zn,Ni—Zn and Pb—Zn.The pair-elements with correlation of P<0.05 were As—Zn,Cd—Hg,Cd—Zn,Pb—Ni.So simply analysis on the causes of relativity was made. |
