Abstract Levels of iron, copper, zinc and lead weredetermined in sediments and soft tissue of the oyster Crassostrea rhizophorae collected from Guacanayabo Gulf, Cuba. Metal-to-Iron ratio in sediments shows an average enrichment for Cu (5,1), Pb(11,7) and Zn (1,3) in the last 20 years. Metal concentrations found in soft tissue of C. rhizophorae are site dependent. The average biotasediment accumulation factors (BSAFs) obtained for Fe, Cu and Pbare less than unity in all cases, indicating that only a little fraction of Cu and Pb in the sediments is bioavailable, independently of their enrichments. Zinc has an average BSAF value of 2.4 andmay represent a serious impact in the area. The concentrations of zinc and copper in some of the oysters are above typical public health recommended limits. Keywords Heavy metals Á Oysters Á Sediments ÁGuacanayabo Gulf
Guacanayabo is the largest gulf of Cuba. Its shores are part ¨ of three provinces: Camaguey, Las Tunas and Granma.
