Evaluate of Heavy Metal Content of some Edible Fish and Bivalve in Markets of Dandong, China
From June to July 2012, the heavy metal contents of Pb, Cd, Cr, Cu, Zn, As and Hg in bivalves and the edible fish in Dandong market were determined by using incomplete digestion - AAS method. The results showed that the enrichment of heavy metals in bivalves was higher than those in fish. Significan...

Zusammenfassung: | From June to July 2012, the heavy metal contents of Pb, Cd, Cr, Cu, Zn, As and Hg in bivalves and the edible fish in Dandong market were determined by using incomplete digestion - AAS method. The results showed that the enrichment of heavy metals in bivalves was higher than those in fish. Significant differences in metal concentrations were found between the tissues of fish. Cd, Pb and Cr were mainly distributed in the scales and gill of the fish. The content of heavy metals in the edible parts of the fish was far below “the human consumption sanitation standard.” The eating quality was good for the edible part of the fish. The content of Cd in bivalves exceeded “the human consumption sanitation standard.” Bivalves containing heavy metals reduced its value for food and attention should be paid on the results. |
