Based on the investigation data of Jiaozhou Bay in May, August and October, 1992, the migration process of Hg content that came from atmospheric subsidence in Jiaozhou Bay was studied. In August, the central point 2016 in the east of Jiaozhou Bay was taken as the source of atmospheric subsidence, with the Hg content of 0.050 μg/L. A series of concentric circles with different gradients have been formed with station 2016 as the center. The Hg content decreased from 0.050 μg/L in the center to 0.021 μg/L in the center of the Bay, 0.037 μg/L in the northwest, 0.031μg/L in the northeast and 0.033 μg/L in the southeast of the bay. According to the absolutely horizontal loss rate model of matter content, it was calculated that in August, in the eastern part of Jiaozhou Bay, from the eastern central water area to the central water area of the Bay, the absolutely horizontal loss rate of Hg content in the surface was 0.40 Yang Dongfang absolute number, 0.19 Yang Dongfang absolute number in the northwest water area of the bay, 0.45 Yang Dongfang absolute number in the northeast water area of the bay, 0.63 Yang Dongfang absolute number in the southeast water area of the Bay. According to the relatively horizontal loss rate model of matter content, it was calculated that in August, in the eastern part of Jiaozhou Bay, from the eastern central water area to the central water area of the Bay, the relatively horizontal loss rate of Hg content in the surface was 8.00 Yang Dongfang relative number, 3.80 Yang Dongfang relative number in the northwest water area of the Bay, 9.00 Yang Dongfang relative number in the northeast water area of the Bay, 12.60 Yang Dongfang relative number in the southeast water area of the bay.
