- Abstract
Based on the investigation data on Cd in Jiaozhou Bay in May, September and October in 1983, were analyzed the horizontal and seasonal distribution, vertical variation and variation range of Pb, revealed the seasonal variation process, settling process and water’s effect of Cd. Results showed that Cd contents in both surface and bottom waters were in orders of spring > summer > autumn. Pollution sources of Cd, particularly river flow determined the variations of Cd in surface waters, as well as in bottom waters.In the waters in the bay mouth in May, September and October, in temporal, spatial, variation, horizontal, and regional scales, the following laws were revealed. As the time change, the variations of Cd in surface and bottom waters were consistent. There were both consistence and contrary of the horizontal variations of Cd in surface and bottom waters. The variation ranges of Cd in surface and bottom waters were basically the same. Cd was tending to be homogeneous in surface and botom waters. The analysis revealed the reapd settling process of Cd, the rapid settling and accumulation effect of Cd, the rapid and continous settlement of Cd, vertical water’s effect of Cd, the processes of river flow discharging and than the settling of Cd.
