Abstract The barnacle Balanus improvisus and the musselMytilus trossulus have been used as biomonitors of thetrace metals Cu, Zn, Cd, Fe, Pb, Mn and Ni at fivesublittoral sites in the Gulf of Gdansk (Baltic Sea) betweenFebruary 2000 and September 2001. The study hasestablished a benchmark against which future biomonitoringprogrammes will be able to establish changes inlocal metal pollution, particularly if metal loadings in theriver Vistula (draining into the Gulf) alter in the future.The study highlighted differences in trace metal bioavailabilitiesto both barnacles and mussels, geographicallyand over time. Accumulated metal concentrations of Cu,Zn, Fe, Pb and Ni, but not Cd or Mn, were correlated inthe barnacles and mussels, suggesting that the bioavailabilitiesof the former metals to the two biomonitorswere similar. The barnacles showed greater discriminatorypower than the mussels as trace metal biomonitors.Concentrations of trace metals in surficial sediments(<63 lm) did not correlate significantly with accumulatedmetal concentrations in either barnacles or mussels,indicating that sediment metal concentrations are notnecessarily good proxy measures of ambient trace metalbioavailabilities to the local coastal filter feeders.
