Effect of Hg in Jiaozhou Bay Waters - Aquatic Transfer Process

Abstract:

Based on the investigation data of Hg in Jiaozhou Bay waters in April, July and October 1986, this paper tried to analysis the horizontal, vertical and seasonal distributions of Hg in Jiaozhou Bay, and to reveal the pollution sources and transfer processes of Hg. Results showed that Jiaozhou Bay had been heavily polluted by Hg, whatever in different seasons. Hg in Jiaozhou Bay was mainly from point sources such as industrial waste and sewage runoff. The horizonal and vertical distributions of Hg content showed the transfer processes as, from estuaries to their outside and the bay mouth, and form surface waters to bottom waters, respectively. The water environmental capacity of Hg in Jiaozhou Bay had been unable to carry the emission load of Hg, and therefore the reduction of emission as well as the improvement of cyclic utilization ratio were the primary processes for Hg pollution prevention and reduction.
