Evaluation of the variegated scallop Chlamys varia as a biomonitor of temporal trends of Cd, Cu, and Zn in the field

Résumé

This study assess the potential of the scallop Chlamys varia as a biomonitor of metal contamination in the field. Cd, Cu, and Zn concentrations were determined in the soft tissues and organs of individuals from the French Atlantic coast sampled over a one year period and belonging to a large range of size. All metals were selectively distributed among the different considered body compartments, and their concentrations were influenced by the size of the specimens or the sampling-season. The present work shows the importance to consider the body compartment, the sampling period and the size as important factors in studies aiming to use this scallop as a biomonitor species. Among tissues, the digestive gland and kidneys exhibited the highest metal concentrations whatever the season or the size. The digestive gland contained 65 and 48 % of the whole Cd and Cu body burdens, respectively, and kidney accounted for 85 % of the Zn load. Those tissues are therefore particularly recommended for use in biomonitoring programs.
