Effect of Hg on Jiaozhou BayWaters – The Change Process of the Hg Pollution Sources

Abstract:

Based on investigation data in Jiaozhou bay waters from 1979 to 1985(absent of 1984), this paper tried to anylysis the horizontal distributions and pollution sources and characteristics of Hg in Jiaozhou Bay. The results showed that, the horizonal distributions of Hg in surface water of Jiaozhou Bay showed decreasing trends from river flow direct, and the major pollution source of Hg was point source, whose pollutants were transferred by stream discharge. Under the influences of point source pollution, the Hg concentrations in surface waters could range from 0.46-13.04 μg.L^-1; while under the influences of ocean current itself, the concentration of Hg in bay mouth area could range from 0.46-13.04 μg.L^-1. The pollution sources of Hg in Jiaozhou Bay could be catagoried as two levels as high-pollution sources and non-pollution sources, due to Hg in this bay was mainly impacted by point source. It is necessary to enhance the recovery ratio of Hg, and to reduce the discharge of Hg.
