“…The spatial variation in sediment contaminant content seems to be driven also by variation in grain size distribution, which in the Stagnone follows a concentric pattern, with silt and clay more concentrated in the Centre of the basin (Vizzini 2000). As an example, in South, As content showed averaged values lower than the ranges reported for other Mediterranean lagoons (e.g., Nador lagoon-Morocco, Ruiz et al 2006), whereas in Centre, values were similar to those for contaminated lagoons (e.g., central part of Venice lagoon-Italy, Bellucci et al 2002). Moreover, As, Cd, and THg showed values approaching or exceeding the Italian regulatory limits (Gazzetta Ufficiale della Repubblica Italiana D.M.…”

Trace element accumulation is particularly important in coastal and transitional environments, which act as contaminant buffers between the continental and marine systems. We compared trace element transfer to the biota in two locations with different open-sea exposures in a semi-enclosed marine coastal area (Stagnone di Marsala, Sicily, Italy) using isotopically reconstructed food chains. Samples of sediment, macroalgae, seagrasses, invertebrates, fish, and bird feathers were sampled in July 2006 and analysed for stable carbon and nitrogen isotopes (d 13 [Pb]). Trophic magnification factors were calculated through the relationships between trace elements and d 15 N in consumers. As and Pb were greater in organic matter sources (sediments and primary producers), whereas Cd and THg were greater in bird feathers. At the food chain level, an insignificant trophic transfer was found for all elements, suggesting biodilution rather than biomagnification. Sediments were more contaminated in the location with lower open-sea exposure. Macroalgae and seagrasses overall mirrored the spatial pattern highlighted in sediments, whereas differences between the two locations became further decreased moving toward higher trophic levels, indicating that trophic transfer of sediment and macrophyte-bound trace elements to the coastal lagoon food chain may be of relatively minor importance.

“…That area receives the cooling waters from a thermoelectric plant (Socal et al, 1999;Facca et al, 2002a,b) and clams grow bigger and more rapidly than anywhere else in the lagoon. However, clam-fishing and clam-farming in that area are forbidden (Orel et al, 2000), because water and sediments are highly contaminated (Marcomini et al, 1997;Bellucci et al, 2000Bellucci et al, , 2002. Nevertheless, recent studies (Secco et al, 2005;Sfriso et al, 2005c;Bernardello et al, 2006) have provided evidence that the nutrients and contaminants recorded in that area have recently decreased significantly.…”

“…Tapes philippinarum, characterized by a rapid growth and spread, soon colonized the lagoons and estuaries of the Venice region, growing mainly in the inner areas affected by trophic inflows. Those areas display high nutrient, organic matter, phytoplankton and microphytobenthos concentrations (Facca et al, 2002a,b;Sfriso et al, , 2005d which favour clam growth but, unfortunately, also exhibit high concentrations of pollutants such as some metals (Donazzolo et al, 1984;Marcomini et al, 1997;Bellucci et al, 2002;Bernardello et al, 2006).…”

a b s t r a c tThe concentration changes of 12 metals (As, Hg, Cd, Cr, Co, Cu, Pb, Mn, Ni, V, Zn, Fe, and Hg) in the soft tissues of Tapes philippinarum during growth were investigated. Clams were seeded in two contaminated areas of the Venice lagoon (San Giuliano and Fusina) and in an area of the Marano lagoon (Lignano Sabbiadoro) close to the clam-farm where the seed was produced. Metal trends were very different according to the considered element, the study site and the growth period. Arsenic was always higher in clam tissues than in surface sediments and suspended particles in all the three stations. Mercury, Cd and Cu were higher in the clams from Marano and Fusina but not in those from San Giuliano. Zinc and Co in clams exceeded the concentrations in the sediment and suspended particles only at Marano. The other elements (Cr, Pb, Mn, Ni, and Fe) were always higher in SPM and sediments. In general metal concentrations in clams were more highly correlated to concentrations in the suspended particles rather than in the surface sediments and in suspended clams rather than in bottom clams, nevertheless significant differences between stations and contaminants were found. Metal concentrations in clams were always lower than the European regulatory limits.Published by Elsevier Ltd.

“…Given the restricted geographical coverage of this study of an isolated mangrove community within a small bay it is difficult to read too much into the significance of these differences but some variation may be attributed to effects of biological and physical phenomena, such as tidal inundation, salinity changes, wind and waves. These phenomena allow the processes of bioturbation, re-suspension and erosion that are known to affect the metal concentrations in surface sediments (Bellucci et al, 2002). The unvegetated zones in Punta Mala Bay were characterised by highly reducing, algal covered black mud.…”
