The common dolphin (Delphinus delphis) is one of the most abundant species in Atlantic Iberia, representing potentially important tool to assess the bioaccumulation of trace elements in the Iberian marine ecosystem. Nine elements (As, Cd, Cu, Hg, Mn, Ni, Pb, Se and Zn) were evaluated in 36 dolphins stranded in continental Portugal. Dolphins had increasing Hg concentrations (16.72 mu g center dot g(-1) ww, liver) compared with previous studies in Atlantic Iberia, whereas Cd concentrations (2.26 mu g center dot g(-1) ww, kidney) fell within reported ranges. The concentrations of some trace elements (including Cd and Hg) presented positive relationships with dolphin length, presence of parasites and gross pathologies. Common dolphins may help biomonitoring more offshore Atlantic Iberian areas in future studies, which would otherwise be difficult to assess. (C) 2016 Elsevier Ltd. All rights reserved.
