【摘要】 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。更多还原

【Abstract】 The 83 sediment samples used in the study were collected from two sediment cores off Zhejiang Coast. These samples were absolutely free from conta-mination caused by human activities, and were taken from the clayey silt and silty clay fractions. All of the layers where the samples were collected belong to marine facies sediments.All of the samples were determined for Fe, Mn, Al, Ti, Sr, Cu, Pb, Zn Ni and Co, 55 samples of them were determined for Cd also. The relationships between iron and other elements were studied. Their linear regression equation and correlation coefficients were also calsulated.更多还原
