“…Hence, there may be multiple sources of contamination which are yet to be specified in the more contaminated sites of Bravone, Aregno, Villefranche, La Vesse and Corbière. However, levels determined in this study (7.5-22.9 g g DW −1 ) were clearly lower than those determined by Conti et al (2007) at Ustica Island (31.9 ± 15.8 g g DW −1 ; Sicily, Italy) where TE contamination was estimated at a mediumlow level according to the literature. All sites sampled can thus be considered as having a low level of Cu contamination.…”

a b s t r a c tLevels of Be, Al, V, Mn, Co, As, Se, Mo, Ag, Sn, Sb, Bi as well as of Cr, Fe, Ni, Cu, Zn, Cd and Pb in Posidonia oceanica (L.) Delile from the Mediterranean French coast were analysed using DRC ICP-MS. The first twelve elements have not been well studied and can be considered to be potential pollutants as a result of potentially increased levels resulting from anthropogenic activities. Spatial variation and/or compartmentalization were found for all trace elements. Except for Al, Cr, Fe, Cu and Ag, most trace elements were preferentially accumulated in photosynthetic tissues, suggesting uptake from the water column. Moreover, for Be, V, Mn, Co, Ni, As, Mo, Sb, Sn and Pb, adult leaves had higher levels than intermediate leaves, suggesting low kinetics of accumulation. Levels in the third intermediate leaf were representative of the average levels of the integral shoot, and thus can be used alone in chemical biomonitoring. For most of the twelve little-studied trace elements, the background levels of the northwestern Mediterranean Sea can be measured, and their spatial variation can be related to anthropogenic activities. Levels of the seven widely studied trace elements seem to decrease or stabilize over time, probably due to their reduced anthropogenic use. These observations show that P. oceanica is a sensitive bioindicator for the monitoring of chemical contamination of a large number of trace elements.

“…Bioaccumulation factors values based on whole plant-seawater comparisons for copper, zinc, cadmium, and lead and C. nodosa were between 380 and 12,500 [64] and between 550 and 36,000 for cadmium, chromium, copper, lead, and zinc and P. oceanica (leaves-filtered seawater) [32]. Bioaccumulation factors values ranged approximately from 2 to 30 for cadmium, chromium, copper, lead, and zinc and P. oceanica collected from a marine reference area [39].…”

“…Concentrations of copper, chromium, cadmium, lead, zinc, and mercury have been reported for surface waters over grass beds containing Cymodocea nodosa, Thalassia testudinum, and Posidonia oceanica in coastal areas of Venezuela, Greece, France, and Italy [32,[39][40][41][42][43]. Mean concentrations (g/L) reported in these studies have ranged between 1 and 42 (copper), 0.12 and 0.32 (chromium), 0.14 and 1.5 (cadmium), 0.7 and 7.8 (lead), 7.7 and 51.0 (zinc), and 0.001 and 3.0 (ng/L, mercury).…”

“…Reviews that summarize the fate and effects of anthropogenic chemicals in seagrass ecosystems are also available. However, these reviews, with few exceptions [37], have been usually either chemical or species specific [30,38,39]. The objective of this review is to provide an expanded perspective on the fate and effects of anthropogenic chemicals on seagrasses.…”

Abstract-Impacts of human-related chemicals, either alone or in combination with other stressors, are important to understand to prevent and reverse continuing worldwide seagrass declines. This review summarizes reported concentrations of anthropogenic chemicals in grass bed-associated surface waters, sediments, and plant tissues and phytotoxic concentrations. Fate information in seagrass-rooted sediments and overlying water is most available for trace metals. Toxicity results in aqueous exposures are available for at least 13 species and a variety of trace metals, pesticides, and petrochemicals. In contrast, results for chemical mixtures and chemicals in sediment matrices are uncommon. Contaminant bioaccumulation information is available for at least 23 species. The effects of plant age, tissue type, and time of collection have been commonly reported but not biological significance of the chemical residues. Experimental conditions have varied considerably in seagrass contaminant research and interspecific differences in chemical residues and chemical tolerances are common, which limits generalizations and extrapolations among species and chemicals. The few reported risk assessments have been usually local and limited to a few single chemicals and species representative of the south Australian and Mediterranean floras. Media-specific information describing exposure concentrations, toxic effect levels, and critical body burdens of common near-shore contaminants is needed for most species to support integrated risk assessments at multiple geographical scales and to evaluate the ability of numerical effects-based criteria to protect these marine angiosperms at risk.
