Migration Paths of Anthropogenic Cd to Jiaozhou Bay

摘要：

　　Using investigation data on Cadmium(Cd)in May and August 1990,this paper analyzed the anthropogenic sources and migration paths of Cd.Results showed that the major Cd sources were river discharge,atmosphere deposition and marine traffic,whose source strengths were 1.56 μg L-1,1.21-1.26 μg L-1 and 1.02 μg L-1,respectively.The source strengths were all higher than 1.0 μg L-1 but lower than 5.0 μg L-1 that were conform to Grade II in according to China Sea Water Quality Standard(GB 3097-1997).The source strengths of Cd in study period were still weak in general.The migration paths of anthropogenic Cd to Jiaozhou Bay were 1)anthropogenic Cd was discharged to the land,2)anthropogenic was discharged to the atmosphere,and 3)Cd was discharged to the ocean.Furthermore,a block diagram model was provided to demonstrate these migration paths.
