Based on the investigation data of Jiaozhou Bay in 1992, this thesis studied the present situation and horizontal distribution of Hg content in the bottom of Jiaozhou Bay mouth. The results showed that in May, August and October, the range of Hg content in the bottom ofJiaozhou Bay was 0.007-0.040 μg/L, which was in line with the national water quality standard for class I seawater. This showed that in terms of Hg content, the bottom water of Jiaozhou Bay from the center of the bay to the south of the bay mouth was not polluted by any Hg content in May, August and October. In the bottom of Jiaozhou Bay, in May, the range of Hg content in Jiaozhou Bay was 0.013-0.019 μg/L. In August, the range of Hg content in Jiaozhou Bay was 0.021-0.025 μg/L. In October, the range of Hg content in Jiaozhou Bay was 0.007-0.040 μg/L. Therefore, in May, August and October, the water of Jiaozhou Bay was not polluted by any Hg content. In May, a high sedimentation of Hg contentwas in the coastal waters of the eastern part of the Bay. In August, a high sedimentationof Hg content was in the coastal waters and the estuary waters in the east of the Bay. In October, a high sedimentation of Hg content was in the south of the bay mouth. However, from May to August, and then to October, the lowest Hg content sedimentationwas in the central waters of the Bay.
