Labelled Zn was mainly accumulated in the digestive gland (65%) and Co in kidneys (81%); Cd and Mn were similarly distributed in digestive gland and gills. In a complementary field study, Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, and Zn were analysed in scallops collected at two stations showing different contamination levels. Digestive gland and kidneys displayed the highest concentrations. Ag, As, Cd, and Fe differed in soft tissues from the two stations, suggesting that Comptopallium radula could be a valuable local biomonitor species for these elements. Low Mn and Zn concentrations found in kidneys suggest that their content in calcium-phosphate concretions differs from the other pectinids. Preliminary risk considerations suggest that As would be the only element potentially leading to exposure of concern for seafood consumers. specialized tropical environment trace elements arsenic radiotracers pectinidae risk assessment bioindicator species 036 152 3 543-552 2008 0269-7491 https://www.documentation.ird.fr/hor/fdi:010042554 10.1016/j.envpol.2007.07.009 0269-7491 [F B010042554] https://www.documentation.ird.fr/hor/fdi:010042554 https://www.documentation.ird.fr/intranet/publi/2008/05/010042554.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-05-30 2017-08-23 fdi:010042554 fre
