英文摘要 | This paper analyzed the seasonal variation, vertical variation and horizontal distribution of Pb in Jiaozhou Bay using investigation data in April and July 1989. Results showed that Pb contents in surface and bottom waters April 1989 were 9.96-11.03 mu g L-1 and 8.15-10.10 mu g L-1, respectively, while in July 1989 were 6.47-15.17 mu g L-1 and 3.39-7.15 mu g L-1, respectively. The pollution level of Pb in bottom waters in April and July 1989 could be considered as heavy and moderate, respectively. The seasonal variations of Hg in both surface and bottom waters were summer > spring. Hence, the seasonal variations of Hg in surface and bottom waters were same. The vertical migration processes of Pb in waters in April and July 1989 revealed the accumulation effect and dilution effect. The seasonal variations of Pb contents in surface waters were determined by the changes of the major Pb sources, while in bottom waters were determined by both the source input and vertical water's effect. The horizontal distributions of Pb in surface and bottom waters in April 1989 were opposite, yet the horizontal distributions of Pb in surface and bottom waters in July 1989 were consistent. The horizontal distributions of Pb contents in surface waters were determined by the changes of the major Pb sources, while in bottom waters were determined by both source input and the inputting time. |
