Quantitative Hg Content Migration Process II. Yang Dongfang Migration Model Application

Abstract 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. According to the absolutely and relatively horizontal loss rate model of matter content, the results showed the facts: A series of concentric circles with different gradients have been formed with station 2016 as the center. Taking the central station 2016 in the east of Jiaozhou Bay as the source of atmospheric subsidence, the Hg content decreased towards surrounding waters. The absolutely horizontal loss rate value of Hg content was between 0.19-0.63 Yang Dongfang absolute number, and the relatively horizontal loss rate value of Hg content was between 3.80-12.60 Yang Dongfang relative number. The sequence of Hg content from low to high was : the central water area of the bay < the northeast water area of the bay < the southeast water area of the bay < the northwest water area of the bay, and the sequence of Hg content absolutely horizontal(relatively) loss rate value from low to high was : the northwest water area of the bay < the central water area of the bay < the northeast water area of the bay < the southeast water area of the bay. The Hg content showed the starting point value of the source point, the end point value of the water area. And the absolutely(relatively) horizontal loss rate value of the Hg content showed the migration process value of the water area from the starting point to the end point. This revealed that the starting point, end point and process value of Hg content showed the migration process of Hg content in water. According to the Yang Dongfang horizontal loss rate model of substance content, the migration and change process of Hg content decreasing along the gradients to surrounding waters could be calculated and quantified.
