Abstract
Sedimentation and accumulation are important transporting processes of pollutants in marine bay, and the quantification of these processes are essential to pollution control. Jiaozhou Bay is a semi-closed bay located in Shandong Province, China. Based on investigation data on Cd during 1979—1983, this paper analyzed the vertical variations of Cd, and quantified the sedimentation and accumulation of Cd. Results showed that the absolute sedimentation amount and relative sedimentation amount of Cd were 0.23—3.23 μg L-1 and 79.2%—100.0%, respectively, while for absolute accumulation amount and relative accumulation amount were 0.08—1.97 μg L-1 and 75.4%—100.0%, respectively.
