Interspecific comparison of Cd bioaccumulation in European Pectinidae (Chlamys varia and Pecten maximus)

Interspecific and geographical variations of trace element concentrations in Pectinidae from European waters.

Cd, Cu and Zn were analysed in the organs and tissues of the three scallop species from the Bay of Biscay, the variegated Chlamys varia L., the queen scallop Aequipecten opercularis L. and the common scallop Pecten maximus L. for interspecific comparisons. In P. maximus the greatest concentrations of Cd and Cu were found in the digestive gland, whereas the two other species showed similar level...

Antioxidant response of the variegated scallop (Chlamys varia) under anthropogenic impact

The variegated scallop (Chlamys varia L.) is an important economic resource in the aquaculture sector in Spain. The aim of the present study was to determine the oxidative status of C. varia, exposed to anthropogenic activities in waters of the Mallorca Island (Western Mediterranean). Specimens were collected from two locations attending to a different degree of human impact. The first station ...

Subcellular and body distributions of 17 trace elements in the variegated scallop Chlamys varia from the French coast of the Bay of Biscay.

Seventeen elements were analysed in the organs and tissues of the variegated scallop Chlamys varia, from the Atlantic coast of France. Concentration levels were determined in scallops of different sizes sampled in contaminated (La Rochelle Bay) and clean (Re Island) sites. Greater concentrations of Ag, Al, Ce, Cr, La, Mo, Nd, Ti, and V were found in the digestive gland while As, Cd, Co, Cu, Mn,...
