This paper analyzed the content, distribution and source of Zn in Jiaozhou Bay in 1982. Results showed that the Zn contents in surface waters in April, June, July and October ranged from 1.75-167.71 μg.L-1, 8.31-36.97 μg.L-1, 7.05-12.18 μg.L-1 and 1.75-5.25 μg.L-1, respectively. Cu contents in most of the monitoring sites in April were meeting Grade III or Grade IV in National Sea Water Quality Standard (GB 3097-1997). While most of the monitoring sites in June, July and October were meeting Grade I or Grade II. The major Zn sources in the bay was overland runoff, ocean current, and deposition, whose input contents ranged from 37.90-167.71 μg.L-1, 1.31-36.97μg.L-1 and 1.75-12.18 μg.L-1. |
