Abstract :
Based on investigation dada on Cadmium (Cd) in surface waters in Jiaozhou Bay in 1982, this paper analyzed the content, distribution and source of Cd. Results showed that The content of Cd in April, June, July and October in surface waters ranged from 0.11-0.53 μg.L-1, 0.11-0.21 μg.L-1, 0.12-0.52 μg.L-1 and 0.32-0.53 μg.L-1, respectively. Cd contents were meeting Grade I (1.00 μg.L-1) in National Sea Water Quality Standard (GB 3097-1997), indicating that Jiaozhou Bay was not polluted by Cd in 1982. Cd contents were decreasing with flow direction of the major inflow river in the northeast, indicated that riverine dischaged was one of the major sources of Cd in Jiaozhou Bay.
