【 摘 要 】

Using investigation data on Cadmium (Cd) in waters in Jiaozhou Bay 1989, we analyzed the spatial and temporal distributions of Cd, and identified the homogenous process of Cd contents. Results showed that by means of vertical water's effect Cd contents in both surface and bottom waters were showing seasonal variations of spring > summer. High Cd contents in surface waters could result in dilution effect in bottom waters, while low Cd contents in surface waters could result in accumulation effect in bottom waters. That was the homogenous process of Cd contents in marine bay. Ocean is a large container in where every substances discharged into would be homogeneous distributed finally no matter the contents are high or low.
