Abstract

Based on investigation data on Pb in bottom waters in Jiaozhou Bay in different months during 1979-1983, we analyzed the seasonal variations of Pb contents and pollution levels. Results showed that the pollution levels during 1979-1983 were light/moderate, and the pollution levels in the bay mouth were seem to be higher than in the other regions. Since stream flow and atmosphere deposition were two of the major sources of Pb in Jiaozhou Bay, whose source strengths of stream flow and atmosphere deposition were highest in August, the pollution levels of Pb in summer were higher than the other seasons. By means of vertical water's effect, the low values in bottom waters were relative stable, and the variations were relative small, and therefore the different of the high values of each month was higher than the different of the low values of each month.
