Cd, Cu and Zn concentrations in sediments and the invasive bivalves Limnoperna fortunei and Corbicula fluminea at the Rio de la Plata basin, Argentina

Cd, Cu and Zn content in sediments and bivalves (Limnoperna fortunei and Corbicula fluminea) were studied in the lower 500 km stretch of the Parana River and in the right margin of the Rio de la Plata Estuary. Both bivalves species showed higher metal contents at the Parana River, possibly related t...
