Plumbum Sink and Transfer Process in Jiaozhou Bay

Abstract:

In order to provide background information and scientific basis for pollution control of Pb, this paper analyzed the sink and transfer process of Pb in Jiaozhou Bay. Results showed that Pb in Jiaozhou Bay was mainly sourced from agricultural non-point source and urban point source, as well as atmosphere dry and wet deposition, leading to the contents of Pb were increasing from spring to summer, and decreasing in autumn and winter. Due to Jiaozhou Bay is a closed bay, the narrow bay mouth is vital to the water exchange, which is the force of horizontal distributions. Horizontal diffusion and vertical deposition were the two major transferred processes of Pb, leading to a large amount of Pb was finally transferred to the sea bottom of the bay mouth areas, and the sea bottom of bay mouth areas was the sink of Pb in Jiaozhou Bay.
