摘要

受多来源沉积物污染影响的水体中可溶性P

Zn实际浓度常明显低于按各自沉积物的比例与释放量计算的理论值。沉积物之间的性质差异越大

实际测定值与计算值之间的差异也越大。多来源沉积物水体中可溶性P

Zn的浓度主要受P

Zn释放能力最强或对P

Zn吸持能力最强的沉积物比例控制。

Abstract

Phosphorus

Cu and Zn concentrations in surface water are controlled by a complex reaction of soluble P

Zn with sediments. This study investigated P

Zn concentrations in solution when various sediments were mixed. In the system where two or three sediments were mixed

the measured soluble P

or Zn concentration were always lower than the predicted values caclulated based on the compositions of sediments

indicating the soluble P

Cu or Zn released by one sediment could be resorbed by another sediment. This resorption may result in lower than expected solution P

Zn concentrations in some surface water. Soluble P

and Zn concentrations in water where the sediments came from multi-sources were controlled mainly by the sediment that had strongest adsorption capacity to P

or strongest potential to release P

Zn.
