Abstract

We applied the definition and structural model of environmental dynamic value of substance in marine bay and the variables including basic background value, environmental background value, input value and environmental dynamic value in analyzing the change process and change trend of Cd in Jiaozhou Bay, eastern China based on investigation data on Cd in May, August and November 1979. Results showed that the basic background value of Cd was 0.02-0.04 g L-1, the environmental background value of Cd was 0.01-0.04 g L-1, the input of Cd from river flow was 0.07-0.85 g L-1, the input of Cd from marine current was 0.25 g L-1, and the environmental dynamic value of Cd was 0.01-0.85 g L-1. The identification of change process and the change trend of Cd provided scientific basis for division of grade standards of Cd in marine bay.
