Abstract

This paper analyzed the influence of water exchange on spatial distribution of Hg in Jiaozhou Bay China based on investigation data on Hg in surface waters in April, July and October 1988. Results showed that Hg contents in surface waters in April, July and October 1988 were 0.045-0.100 g L-1, 0.031-0.064 g L-1 and 0.024-0.104 g L-1, respectively. The two major Hg sources in Jiaozhou Bay were overland runoff and river flow, whose source strengths were 0.068-0.104 g L-1 and 0.061-0.074 g L-1, respectively. A block diagram model was provided to reveal the changing of Hg contents during migration processes, i.e., human emission, overland transport, river flow transport and oceanic transport. Hg in Jiaozhou Bay was mainly input from major sources located in the west, north and east of the bay, and Hg contents in the bay were relative high. However, Hg contents in the open waters were still relative low. Hence, by means of water exchange, there was a equivalent peak surface (0.050 g L-1) in the bay. These findings were showing the influence of water exchange on Hg contents in this semi-closed bay.
