Abstract:The data of mercury contents of marine products included 82 samplings of coastal provinces, published from 1991 to 2011. The spatial distribution and change trend of the mercury contents were analyzed. The sequencing of the provinces where the marine produced according to the average mercury content is Jiangsu>Zhejiang>Fujian>Guangdong>Liaoning. In four kinds of marine products, the sequence of mercury contents was Molluscs >Fish>Shellfish>Shrimp and Crab. In China, the mercury content in Shellfish maintained a low level before 2005, but increased gradually after 2005, reached the highest value in 2010, and then declined. The mercury content in fish, Shrimp and Crab increased after 2005, reached the highest value in 2009, and then declined. The average mercury content in marine products of every province in our country was qualified. The sea area of the highest of biological quality standards was 84.6%.
