- Abstract:
-
The appraisal of the present heavy metals pollution is made by blurred mathematics in the soil-plant system of Wolongquan river basin.The results indicated that the heavy metals pollution are terribly serious in the soil-plant system upper and medium Wolongquan river basin.Thereinto,the contaminative factors of soil are mainly Cu,Pb and the contaminative factors of paddy and maize are respectively Pb,Cu,Cr,As and Pb,Cr,Hg in upper Wolongquan River basin,and the contaminative factors of paddy and maize are respectively Pb,Cu,Cd,Cr,As and Pb,Cr,As,Hg in Wangjiawaizi district.The extent of heavy metal pollution are less in dryfarming soils of hydrogenide plant and in woodland soil of Kaoshan village and contaminative factors are respectively Pb,Zn,Cu,Hg and Hg,As,Pb,Cd,Zn.The levels of heavy metals are less than correspounding background of soil heavy metal in dry farming soil of Wanfu district down Wolongquan River and surfacial soil in west hill land of Wangjiawaizi district.The pollution of Pb,Zn,Hg in the leeks are grievous in Wangjiawaizi district and in Wanfu district.Different plants in same district have different contaminative factors and the ripe or maize in different districts have different contaminative factors.
