Dear MARMAM community, My co-authors and I are pleased to share our recent publication in Chemistry and Ecology entitled Metals concentration and bioaccumulation in the marine-coastal trophic web from Buenos Aires province southern coast, Argentina. Vilches, F.O., Bobinac, M.A., Labudía, A.C., Paso Viola, M.N., Marcovecchio, J.E., Cappozzo, H.L. & Panebianco, M.V. 2019. Metals concentration and bioaccumulation in the marine-coastal trophic web from Buenos Aires province southern coast, Argentina, Chemistry and Ecology, 35:6, 501-523, DOI: 10.1080/02757540.2019.1604693 Metals accumulated in the tissues of organisms inhabiting marine ecosystems generally reflect their bioavailable levels within that environment. The aim of this work was to study the presence and concentration of metals (Cd, Cr, Cu, Fe, Ni, Pb and Zn) and its bioaccumulation in liver-ink sac and muscle tissues of loliginid squids, Loligo sanpaulensis, in liver and muscle tissues of white croakers, Micropogonias furnieri, and in muscle tissues of franciscana dolphins, Pontoporia blainvillei, as representatives of different trophic levels of an estuarial ecosystem from the southern coast of Buenos Aires. Except for Pb, all metals were detectable in the hepatic tissues. Bioaccumulation was observed for Fe, Cr and Ni in muscle of squids. Zn levels in muscle samples increased with the trophic level of the species analysed. Necochea-Quequén presents relatively high levels of Ni and Cr in the tissue samples of squids and fishes given other locations of southern hemisphere, indicating a possible anthropic enrichment. These outcomes provide the necessary basis for the environmental monitoring of an area with relevance for fishing and high anthropic activity.
