The spatial migration pattern of Hg content for the prediction of disease during a long time

According to the survey data on the waters of Jiaozhou Bay from 1986 to 1990, in the terms of space, through analysis on the data about Hg content every year, including the degree of content, the horizontal, vertical and seasonal distribution, we studied the sources, distribution and migration of Hg, and the water quality of Jiaozhou Bay and obtained the migration patterns of Hg. In terms of time, through the discussion on the data of Hg content during five consecutive years from 1986 to 1990, we determined the changes happened in time and space of Hg content and obtained following results: (1) the changing process of Hg in years and mouths and its model; (2) the changing process of sources of Hg on the basis of time and space. Those patterns and changing process based on time and space laid a solid theoretical foundation of the migration process of Hg in water bodies.
