A mussel watch in the Ria Formosa lagoon

A mussel watch in the Ria Formosa lagoon

The present work analyzes the concentrations of various metals (Ag, Cd, Cr, Cu, Ni, Pb and Zn) in the edible part of the mussel Mytilus galloprovincialis from the Ria Formosa lagoon (Portugal). Mussels of a similar size (5–7 cm) were collected. The results indicate that the dispersion and accumulati...

Mussels of a similar size (5–7 cm) were collected. The results indicate that the dispersion and accumulation of metals in mussels is influenced essentially by the sources of pollution and the bioavailability of the metal. The highest concentrations of Ag, Cu and Ni occurred in the mussels from sites 1, 6 and 7, which are mainly related to inputs from urban discharges. The highest concentrations of Cr were found in the mussels from sites 2 and 5, located near urban discharges and metallic structures. The highest concentrations of Pb were recorded in the mussels from site 9, associated with fuel from boats and diffuse inputs of this metal. The mussels at sites 3, 4 and 9 presented the highest concentrations of Zn and Cd, probably caused by physical and chemical processes that occur in the boundary between the lagoon and the ocean. The concentrations of Ag and Ni in the mussels of Ria Formosa are relatively low when compared to other geographical locations. The concentrations of Cd, Cr, Cu and Pb accumulated in the mussels reveal low contamination. As for the concentration of Zn, the values in the Ria Formosa mussels are higher in the eastern part of the lagoon than in the western part, revealing signs of contamination by this metal. Se analizaron las concentraciones de varios metales (Ag, Cd, Cr, Cu, Ni, Pb y Zn) en la parte comestible del mejillón Mytilus galloprovincialis de la Ría Formosa (Portugal), para lo cual se recolectaron ejemplares de tamaño similar (5–7 cm). Los resultados indican que la dispersión y acumulación de metales en los mejillones es influenciada esencialmente por las fuentes de contaminación y la biodisponibilidad del metal. Las concentraciones más elevadas de Ag, Cu y Ni se registraron en los mejillones de las estaciones 1, 6 y 7, relacionadas principalmente con el vertido de descargas urbanas. Las concentraciones mayores de Cr se observaron en los mejillones de las estaciones 2 y 5, localizadas cerca de descargas urbanas y estructuras metálicas. Las concentraciones más altas de Pb se presentaron en los mejillones de la estación 9, lo cual se asocia con el combustible de barcos y aportes difusos de este metal. Los mejillones de las estaciones 3, 4 y 9 tuvieron las concentraciones más elevadas de Zn y Cd, probablemente como consecuencia de los procesos físicos y químicos que se presentan en el límite entre la laguna y el océano. Las concentraciones de Ag y Ni en los mejillones de la Ría Formosa son relativamente bajos en comparación con otros sitios geográficos. Las concentraciones de Cd, Cr, Cu y Pb acumuladas en los mejillones muestran poca contaminación. En cuanto a la concentración de Zn, los valores para los mejillones de la Ría Formosa son mayores en la parte oriental de la laguna que en la parte occidental, lo que indica contaminación por este metal.
