As part of a specific monitoring programme, total lead (Pb), cadmium (Cd) and mercury (Hg) concentrations in marine gastropods (common winkle, common whelk, abalone and murex), echinoderms (purple sea urchin and black sea cucumber) and tunicates (an ascidian species) were investigated by the French National Reference Laboratory (NRL) for trace elements in foodstuffs of animal origin. These elements were analysed by atomic absorption spectrometry in order to evaluate the safety of these species for human consumption. The highest levels of Hg and Cd were found in murexes, 0.185 mg kg-1 and 0.853 mg kg-1, respectively; whereas the highest level of Pb was detected in ascidians (0.505 mg kg-1). Hg and Pb concentrations were always below the maximum levels set by the European legislation (0.5 mg Hg kg-1 and 1.5 mg Pb kg-1 wet mass) and for Cd, only 2 samples of murex (2.09 ± 0.42 mg kg-1 and 2.33 ± 0.46 mg kg-1) exceeded the maximum level set by French legislation of 2.0 mg kg-1 wet mass. © 2010 Elsevier Ltd.

Lead, cadmium and total mercury contents have been determined by atomic absorption spectrometry in white and brown meat of 108 batches of crustaceans (lobsters, spider crabs, common crabs, swimming crabs and king crabs) collected in France between April and December 2009. With mean levels of 0.041, 0.132 and 0.128mgkg-1 for Pb, Cd and Hg, respectively, concentrations in white meat were systematically below the European legislation maximum level of 0.50mgkg-1. Cd concentration in the brown meat of common crabs (mean concentration: 11.8mgkg-1 and maximum of 14.3mgkg-1) was well above the observed levels for white meat. The consumption of one whole common crab of 1kg (about 120g of white and brown meat) would not contribute significantly to the Pb and Hg provisional tolerable weekly intake (PTWI) for adults, but the ingested Cd would greatly exceed the TWI of 2.5μgkg-1 body weight, which may be a health issue for consumers of brown meat. Therefore, we recommend moderate brown meat consumption. © 2010 Elsevier Inc.
