The Content of Heavy Metals in the Terrestrial Area at the Intersection of Poyanghu Lake and Yangtse River

CUI Li-juan; ZHANG Man-yin

On the basis of the measurement of the heavy metals As,Hg,Cr,Cd,Pb in the soil and plants on the terrestrial area at the intersection of Poyanghu Lake and Yangtse River(including two sampling plots in Jiujiang-Xingang and Hukou),the difference of the heavy metals in these two plots were compared,and the correlation and curve fitting of the heavy metal contents in the plants and soil were counted and analyzed,and the ecological restoration measures were put forward.The result showed that,the content of Pb(63.56 mg·kg-1) in the soil of Jiujiang-Xingang sampling plot was higher than that(53.12 mg·kg-1) of Hukou sampling plot,but the contents of As,Hg,Cr,Cd were not significantly different.In Jiujiang-Xingang and Hukou sampling plots,the contents of Cr,Pb,Cd in the plant roots were higher than that in stems and leaves,but the contents of As and Hg were just contrary,the contents of heavy metals in stems were in the medium level.Analyzing the correlation of the heavy metal contents in plants and soil among all sampling plots,the results are as follows: the contents of Hg,Pb in plant and soil were correlated,but As,Cd,Cr were not.
