| Distribution Regularity of Heavy Metals in North China Plain and Its Significance |
| In order to detect the distribution of heavy metals in the North China Plain, the authors drew element geochemical maps of As, Hg, Cr, Cu, Ni, Pb and Zn on the basis of geochemical investigation data obtained from 3 provinces and 2 cities in the North China Plain since 2002. Distribution regularity of these heavy metals was discussed in this paper, and causes were analyzed too. Based on geochemical maps of these 7 heavy metal elements, the authors further compiled a comprehensive evaluation map of heavy metal elements, which intergratedly expresses the distribution of heavy metal elements in the North China Plain. An analysis of the comprehensive evaluation map was also made. The conclusions drawn from the comprehensive evaluation map in combination with the element geochemical maps can provide scientific basis for agricultural, environmental, medical and other policy-making departments of the government. |
