According to the investigation data of Jiaozhou Bay in 1991, the Hg content and horizontal distribution at bottom layer were studied. The results showed that the variation range of Hg content was 0.011-0.054μg/L, which satisfies the Case I and II Sea Water Quality Standard. Therefore, in May, August and October, the bottom layer from bay center to southern bay mouth was mildly polluted or not polluted by Hg content. In May and August, the bottom layer of eastern nearshore waters was mildly polluted by Hg content, and in May, August and October, other areas were not polluted by Hg content. There was high sediment of Hg content in eastern nearshore waters. In other words, Hg content first reached the surface waters, and then sedimented to bottom layer of eastern nearshore waters.
