Abstract

This paper analyzed the seasonal variations and land-ocean transfer process of Pb in Jiaozhou Bay based on investigation data in surface waters in different seasons during 1979-1983. Results showed that during 1979-1983, both stream flow and marine current were the major Pb sources in Jiaozhou Bay. However, the inputs of Pb from atmosphere deposition and the top of the island were not beginning until 1981, and the inputs of Pb from marine traffic was not beginning until 1983.The seasonal variations of Pb contents in this bay were mainly determined by the inputs of Pb by anthropogenic activities, particularly the variations of the sources strengths. The land-ocean transfer of Pb could be expressed by a block diagram model, which indicated that Pb contents in the marine bay were mainly determined by the strength and frequency of Pb inputs from anthropogenic activities, and meanwhile, Pb was moving from high content areas to low content areas in the ocean interior.
