摘要：By the investigation dataset on Plumbum (Pb) in surface and bottom waters in waters from the bay center to the bay mouth in Jiaozhou Bay 1990, the analysis in this paper unveiled the seasonal variation and horizontal distribution of Pb. the results would determine that In May and August 1990, Pb contents in surface waters in Jiaozhou Bay were 4.64-13.39 μg L−1 and 3.84-11.01 μg L−1 respectively, compared to 4.64-9.41 μg L−1 and 2.96-8.86 μg L−1 summer in both surface and bottom waters. The source inputs of Pb to this bay were different in different seasons and locations, resulting in different seasonal variations of Pb contents in surface waters. By means of vertical water's effect, Pb in surface waters were migrating to bottom waters continuously, resulting in the horizontal distributions of Pb in surface and bottom waters were consistent. Pb contents in bottom waters were relatively high/low in case of Pb contents in surface waters were relatively high/low. The seasonal variations of Pb contents in surface waters were mainly influencing by the source inputs, while in bottom waters were mainly influencing by the source input and the sediment process. The horizontal distributions of Pb in surface and bottom waters were consistent in different seasons. In any seasons, or under influences of different major sources, the horizontal distributions of Pb contents in surface and bottom waters were consistent.
