摘要

Abstract

The complexation capacity of Cu and Pb and their labile and organic contents were determined separately for surface seawater samples from Yueqing Bay. The samples were prepared using Nuclepore filtration method yielding <1.0 μ

<0.4μm and <0.2μm particulate water samples. Our data indicated that the <0.2μm colloidal fraction is a major carrier for distribution of copper in seawater. Affinity of Cu to marine microparticles plays an important role in the process. Pb however

tends to be absorbed by >0.2μm particles. The complexation capacity of Pb with <0.2μm particulates was smaller than that with 0.2–1.0μm particulates

and averaged 11.5 and 23.0nmol/L respectively. The results suggested that colloidal particles were responsible for the distribution and concentration of Pb in seawater.
