Abstract
Carbon and nitrogen stable isotopes and trace metals (Hg, Cd, Cr, Ni, Cu, Pb, Zn) were measured in benthic organisms from the marine area ou tside the Sacca del Canarin lagoon in the Po delta. The results of del ta(13)C and delta(15)N determinations permitted the reconstruction of the foodweb composed of filter-feeders, deposit feeders, fish predator s and scavengers. Significant interspecies differences in metal concen trations were found and are discussed in relation to feeding habits an d trophic level. (C) 1998 Elsevier Science Ltd. All rights reserved.
