【 摘 要 】

Using investigation on Cd in May and August, 1990, this paper analyzed the spatial and temporal variations of Cd contents in Jiaozhou Bay. Results showed that in May, 1990, Cd contents in surface waters and bottom waters were 0.35-1.02 μg L-1 and 0.11-0.35 μg L-1, compared to 0.22-1.26 μg L-1 and 0.18-0.48 μg L-1 in August, 1990. The pollution level of Cd in this bay in 1990 was still slight. Cd contents were confirmed to Grade I and Grade II, and the pollution level of Cd in this bay in 1990 was still slight. Cd contents in both surface and bottom waters were in order of spring
