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...

Corbicula fluminea Invasive bivalves Limnoperna fortunei Metal content Parana River Rio de la Plata Estuary bioaccumulation heavy metal mollusc sediment pollution water chemistry 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 to water chemistry. The Parana water is circumneutral and soft, while the Rio de la Plata coastal water is alkaline, hard, with a higher organic content. Bivalves sampled at the thermal effluent of the Atucha Nuclear Power Plant, at the Parana River, showed the highest metal content, either from increased absorption at the higher water temperatures (12 °C higher than the river water) or from metal corrosion of the power plant cooling system. L. fortunei and C. fluminea appeared to be successful biomonitor organisms for Cd pollution in the basin, while Cu and Zn content in bivalve tissues was apparently not related to metal load.
