Abstract
Dietary exposure of the French population to many chemical and natural substances has been assessed in the second national Total Diet Study (TDS) published in 2011. The data presented in this paper have been specially prepared for the 8th ICMSS conference to estimate the contribution of the shellfish consumption to the overall dietary exposure to chemical contaminants. Compounds studied include 15 trace elements (Pb, Cd, Hg, Al, As, Sb, Ag, Co, Cr, Mn, Mo, Ni, Se, Sn, V), 17 PCDD/F and 12 DL-PCBs, 6 NDL-PCBs, 4 PAHs, 16 perfluoroalkylated substances (PFAs), 8 PBDEs, 3 PBBs, 3 isomers of HBCDs, and 54 pesticides. The highest contributions were observed for silver and PAHs. Silver exposure from shellfish represented 16 % of the overall dietary exposure for adults and 4.3 % for children. PAHs exposure (based on the sum of 4 compounds) contributed to 13 and 4 % of the overall dietary exposure for adults and children respectively. The contributions for the other contaminants to the overall dietary exposure were between 5 and 1 % for cadmium, lead, dioxins, PCBs, below 1 % for the other trace elements, PFAs, PBDEs, PBBs, HBCDs and below 0.1 % for pesticides.

Upper bound assumption: a non-detected substance is considered as present at the limit of detection, and a detected but non-quantified substance is considered as present at the limit of quantification. The upper bound assumption over estimates levels and thus exposure and is therefore conservative.
