摘要：By investigating the dataset Cadmium (Cd) in Jiaozhou Bay from 1984 to 1988, In the paper showed horizontal distributions of Cd, the major sources, and the changes of the major sources. Results unveiled that the major Cd sources during this time period were marine current, river discharge and atmosphere deposition, whose source strengths were 0.12-6.48 μg L−1, 0.12-1.07 μg L−1 and 0.04 μg L−1, respectively. During this time period, the source input from marine was sometimes weak and sometimes strong. The source input from river discharge was changing from little input to relative weak, and then to relative strong. The source input from atmosphere deposition was changing from little input to occurring finally. The human activities resulted in the increasing of the source input of Cd to the bay, and influenced the water quality continuously.
