Copper, zinc and lead bioaccumulation in marine snail, Strombus gigas, from Guacanayabo Gulf, Cuba.
Levels of copper, zinc and lead were determined in sediments and edible muscle of marine snail Strombus gigas collected from Guacanayabo Gulf, Cuba. The concentration range of each metal in marine snail muscle on mg kg(-1) wet weight varied as follows: Cu = 6.4-32.6, Zn = 20.4-31.1 and Pb = 0.2-2.3; and in corresponding sediments (on mg kg(-1) dry weight) as: Cu = 157-186, Zn = 56-94 and Pb = 20-37. The average biota-sediment accumulation factors (BSAFs) obtained for studied metals are less than unity in all cases, indicating that only a little fraction of metal content in the sediments is bioavailable, independently of their possible enrichments in the sediments. The concentrations of copper and lead in some of the marine snails are above typical public health recommended limits.
