Effect of Hg in Jiaozhou Bay Waters-Settling Process

Abstract:

Being a close bay, vertical settling was the dominant transfer process of Hg Jiaozhou Bay. Based on the investigation data of mercury (Hg) in bottom waters in Jiaozhou bay in 1979 to 1985 (in absence of 1984), this paper tried to analysis both of the settling processes and settling mechanisms of Hg. Results showed that that Hg in Jiaozhou Bay was settling continually over year, therefore a continued accumulation of Hg contents in bottom waters appeared, especially in spring and summer. Sediments in sea bottom could be both of source and sink of pollutants, especially for persistence pollutants such as Hg. Based on the both of the settling processes and settling mechanisms, the improve of recycle rate and the emission reduction of Hg should be the major pollution control strategies in Jiaozhou Bay.
