通过对婺江江心洲伍佰滩柱样沉积物（76cm）进行多项磁学参数和重金属含量的测定,得到磁性物质和重金属的垂直分布情况。运用SPSS软件对所得数据作主成分分析,分析表明磁学指标χARM/SIRM和χfd%与Fe、Al、Pb、Ga、V、Ce、Cr、Ni、Cu等重金属含量有较强的相关关系,反映了细晶粒亚铁磁性矿物对重金属的吸附作用。建立了利用磁学参数χARM/SIRM和χfd%推断污染较严重的几种重金属含量的线性回归模型。本研究表明利用磁学参数来快速推断河流沉积物的重金属污染状况是可行的。

By Measuring magnetic indexes and heavy metals on a sediment core（76cm） obtained from Wubai beach of Wu River central bar,the vertical distribution of magnetic material and heavy metals is obtained.The principal component analysis using SPSS finds the relationship between（χARM /SIRM,χfd%）and heavy metals like Fe,Al,Pb,Ga,V,Ce,Cr,Ni,Cu,which shows the absorption of heavy metals by fine-grained ferromagnetic minerals and the influence of their grain size on the sediments.Linear regression models are established to estimate the concentration of polluted heavy metals.The study shows it is viable to deduce heavy metal pollution using magnetic parameters.
