This paper analyzed the content, horizontal distribution and migration process of Cd in bottom waters in Jiaozhou Bay based on the investigation of Cd in July and October 1984. Results showed that Cd contents in bottom waters in July and October were 0.05-0.18 Î¼g L-1 and 0.05-0.06 Î¼g L-1, respectively, and were lower than the upper limit for Cd in Grade I (1.00 Î¼g L-1) in Sea water quality standard (GB 3097-1997) of China. Cd contents in July were decreasing from the inside of the bay mouth to the bay mouth, and then the outside of the bay mouth. Cd contents in October were decreasing from the outside of the bay mouth to the bay mouth; and the inside of the bay mouth to the bay mouth in October. The reasons of the sedimentation rates of Cd were different were that high Cd contents were occurring in different areas in surface waters, and the vertical waterâ€™s effect. In generally, Marine current was the major source, whose impacts on Cd contents were very slight in 1984.
