Performance of two Patagonian molluscs as trace metal biomonitors: the overlap bioaccumulation index (OBI) as an integrative tool for the management of marine ecosystems

"In this study, we have investigated Cd, Cr, Cu, Ni, Pb and Zn in the biomonitors Mytilus chilensis and Nacella (P) magellanica sampled along seven selected sampling sites along 170 km of the coastal area of the Beagle Channel (Tierra del Fuego, Argentina) in four sampling campaigns: 2005, 200...
