Input and transfer processes of Cu in bay waters

Abstract

This paper analyzed the input and transfer processes of Cu in waters of Jiaozhou Bay, Shandong Province, eastern China. Results showed that the input of Cu was stream flow discharge and atmospheric deposition; while the major transfer processes of Cu was vertical sedimentation and horizontal diffusion. For seasonal variations, the Cu contents in Jiaozhou Bay were higher in wet season than in dry season. For spatial variation, the Cu contents were higher in surface water than in bottom waters, and were decreasing from the pollution sources to the around areas.
