“…The latter studies indicated that, except for Fe in Ischia and for Pb in the three meadows, the measured metal concentrations averaged background concentrations for the Mediterranean Sea. Thus, concordance between the present study and those of Warnau et al (1995Warnau et al ( , 1998 suggests that, despite their different status in terms of general contamination (Sheppard and Bellamy 1974;Bouquegneau and Martoja 1987;Delmas 1990;Pergent-Martini 1992), the three studied meadows are most probably poorly contrasted regarding heavy metal contamination (at least in terms of bioavailability of these elements).…”

“…The meadow of Calvi is far from any industrialized or urban area; it is therefore usually reported as a reference location (Bouquegneau and Martoja 1987). The meadows of Ischia and Marseille were selected as contaminated areas, since they are subject to anthropogenic and/or natural contamination pressures: the meadow of Ischia is very close (ca.…”

The concentrations of Cd, Cu, Fe, Pb and Zn were measured in holothuroids Holothuria tubulosa collected during different seasons and at several depths in three N W Mediterranean Posidonia oceanica meadows (Calvi, Corsica; Ischia, Italy; Marseille, France). Metals were found to be selectively distributed among the holothuroid body compartments (i.e. body wall, gut, and haemal system). Among the sources of variation taken into account, the major part of the variability observed in metal concentrations was associated to the body compartment factor, then to the seasonal one and, finally, to the geographical and bathymetric factors. Our results suggest that, if one uses H. tubulosa as a bioindicator species for surveying and monitoring metal contamination in the Mediterranean P. oceanica meadows, attention should be paid to compare only concentrations measured in the same body compartments of individuals collected during the same period of the year. Body compartments that should be preferably considered for metal analyses are the haemal system and, secondarily, the gut (i.e. the compartments concentrating metals most efficiently). Due to the peculiar ecological characteristics of H. tubulosa (i.e. a deposit feeder living in close relationships with the sediments), this species could be effectively used to complement the small set of bioindicators available so far for surveying metal contamination in the P. oceanica ecosystem (viz. the phanerogam P. oceanica itself and the grazing echinoid Paracentrotus lividus).

“…Previous studies on the accumulation of metals in H. trunculus showed its usefulness as indicator species for metal pollution (Bouquegneau and Martoja 1987;Catsiki and Arnoux 1987;Dallinger et al 1989;Lorenzini and Orlando 1994;Siboni et al 2004;Roméo et al 2006;Gharbi-Bouraoui et al 2008;Chouba et al 2008;María-Cervantes et al 2009;Lahbib et al 2013). Among these studies, the potential of H. trunculus to monitor particular metals was reported for As, Mn, Pb, Cd, and Zn (María-Cervantes et al 2009), for Cd (Bouquegneau and Martoja 1987;Dallinger et al1989), and for Cd, Cu, and Zn (Lahbib et al 2013).…”

Cd, Zn, Cu, As, Fe, Cr, Ni, Al, and Pb were analyzed in the edible and inedible parts of the muricid gastropod Hexaplex trunculus sampled along the Tunisian coast in 2004, 2007, and 2011. The concentration ranges (μg/g dry weight) in the whole soft tissue were 0.1-19.2 for Cd, 198.7-564.6 for Zn, 31.9-363.1 for Cu, 12.8-177.8 for As, 35.4-179.0 for Fe, 0.0-5.8 for Cr, 0.1-4.6 for Ni, 1.0-41.4 for Al, and 0.0-0.6 for Pb. The highest concentrations were recorded in Gabès for Cd, Menzel Jemil for Zn and Cu, Bizerte channel for As, Zarat for Cr and Pb, and Tunis North Lake for Fe, Al, and Ni. The European standards compiled by FAO for mollusks were exceeded in several localities. The temporal trends revealed a decreasing metal contamination in most sampling stations from 2004 to 2011. The calculated intake of metals (μg/week/kg body weight) through human consumption of the snail edible portion varied from 0.0 to 4.4 of Cd, 55.9 to 172.1 of Zn, 8.7 to 92.7 of Cu, 3.0 to 42.6 of As, 9.5 to 49.1 of Fe, 0.0 to 1.52 of Cr, 0.0 to 1.4 of Ni, and 0.3 to 11.4 of Al. Comparison of these metal intakes with those of the standard provisional tolerable weekly intake (PTWI) values stipulated by the WHO recommends precaution in terms of human consumption of this marine snail.

“…35 mortalities in the creatures would occur and where the suitability of the creature for human consumption would be queried. High and variable concentrations of cadmium have been reported in the tissues of the mollusc Murex trunlus taken in Calvi Bay, Corsica, during the tourist season [94]. Doherty et al [95] have reported the occurrence of a metallothionein-like metal-binding protein in the soft tissues of Asiatic clams following exposure to dissolved cadmium and zinc.…”
