Identification of Cu's high settling region in Jiaozhou Bay

摘要

Cu pollution in marine bay has been one of the environmental issues in the world, and understanding the transporting process of Cu is essential to environmental protection. This paper analyzed the horizontal distributions of Cu in bottom waters in Jiaozhou Bay, and identified the high settling regions based on investigation data on Cu during 1982-1985. Results showed that there were rapid settling processes in the bay, and a big part of Cu was transported to bottom waters. Furthermore, there were accumulation processes in these high settling regions. These findings were helpful information in decision-making of pollution control and environmental remediation practice.
