本文所用的83个样品均采自浙江沿岸浅海两个沉积土柱。采样时避免了人为污染的影响,这些样品均采自粘土质粉砂和粉砂质粘土粒级,所采的样层属海相沉积。 全部样品均测定了Fe、Mn、Al、Ti、Sr、Cu、Pb、Zn、Ni和Co,其中有55个样品还测定了Cd。本文还研究了铁和其他元素间的相关性,计算了它们的线性回归方程和相关系数。 The 83 samples used in this paper were collected from two sedimentary soil columns in the shallow sea of ​​Zhejiang coast. Sampling to avoid the impact of man-made pollution, these samples are taken from the clay and silty silt clay particles, the sample layer is a marine sediment deposition. All samples were measured for Fe, Mn, Al, Ti, Sr, Cu, Pb, Zn, Ni and Co, of which 55 were also tested for Cd. This paper also studied the correlation between iron and other elements, calculated their linear regression equation and correlation coefficient.
