This paper studies the content of Pb in the bottom water of Jiaozhou Bay and its horizontal distribution according to the investigation materials in the year 1991. The results show that the content of Pb in the water of Jiaozhou Bay, in May, August and October, ranges from 5.51 to 38.32ug/L, confirming to the third- and the fourth-class water quality standards. It indicates that in May, August and October, the water quality in the bottom water of Jiaozhou Bay from the central area to the south bay mouth is moderately or severely polluted by the Pb content. Following on, it reveals that the bottom water from the centre of bay to the east, and to the south bay mouth has been polluted seriously by the human emissions of Pb content under the effect of vertical water body. In May, August and October, the bottom water of Jiaozhou Bay in the east part, and the north and south bay mouth all reflects heavy settlement in Pb content.
