Heavy metals in Macoma balthica and extractable metals in sediments from the southern Baltic Sea
چکیده انگلیسی

Concentrations of Zn, Cu, Ni, Fe, Mn, Co and Cd in soft tissues of Macoma balthica and their extractable forms in the adjacent sediments from 15 sampling sites in the southern Baltic Sea were determined by AAS. The samples were collected during cruises of M/S Hestia and R/V Baltica in July–August 2006. In order to estimate the degree of element bioaccumulation in the molluscs with respect to their extractable forms of the associated sediments, the bioaccumulation factor (BF) was calculated. ANOVA clearly indicates spatial differences between the concentrations of the metals, and factor analysis (FA) confirms that spatial variations exist between the concentrations of metals in M. balthica and their extractable forms in the adjacent sediments from the Gulf of Gdańsk and open Baltic waters. This differentiation can be explained by differences in environmental parameters between these two areas. M. balthica may be useful as a biomonitor of heavy-metal bioavailability and contamination in the Baltic Sea.
