Bioaccumulation of copper, lead and zinc by the bivalves Macomona liliana and Austrovenus stutchburyi

► A. stutchburyi accumulated, overall, much lower amounts of metals than M. liliana. ► A. stutchburyi and M. liliana both accumulated Pb and Zn. ► Bioaccumulation of Cu occurred in A. stutchburyi only in the presence of Zn. ► Bioaccumulation of Cu was not evident in M. liliana. ► The presence of Pb could affect the bioavailability and uptake of Cu and/or Zn.
