Abstract:
The biological availability of metals along the length of the Mersey estuary has been reevaluated using macro algae, Fucus vesiculosus, gastropods Littorina littorea, polychaetes Nereis diversicolor, suspension-feeding bivalves Mytilus edulis, Mya arenaria and Cerastoderma edule and deposit-feeding bivalves Scrobicularia plana and Macoma balthica. In the current survey, conducted in May 1993, concentrations of Ag, As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sn and Zn have been measured in sediments and biota and the results compared with data for similar Mersey surveys carried out since 1980. Observations of long-term trends in contamination, species distribution, and abundance are discussed and comparisons are made with conditions found in other UK estuaries. The results will assist in the general quality assessment of the Mersey estuary.
