“…Indeed, p-HBA were also detected among the extractable free and ester-bound phenols in previous studies on P. oceanica (Zapata and McMillan 1979;Cariello et al 1979;Cuny et al 1995;Agostini et al 1998;Dumay et al 2004;Pergent et al 2008). …”

“…The leaves consist primarily of polysaccharides (roughly 60%, two thirds of which corresponds to holocellulose), and the remaining material is largely composed of various phenolic constituents, more specifically lignin, tannin and free and ester-bound phenolic acids (Zapata and McMillan 1979;Agostini et al 1998;Arnold and Targett 2002;Torbatinejad et al 2007). Reported lignin contents of P. oceanica leaves and agaepropili are in the range of 25-30% of their dry weight (Ncibi et al 2009;Khiari et al 2010;Bettaieb et al 2015).…”

“…5-10% in P. oceanica leaves (Pergent et al 2008). Roughly 2% of the dry weight of P. oceanica leaves corresponds to free or ester bound (water-or aqueous/organic solvent mixtures-extractable) phenols (Agostini et al 1998), the molecular composition of which has been examined with relative scrutiny, as reviewed by Heglmeier and Zidorn (2010). The nature of the "remaining" phenols (total phenols minus lignin, tannin and extractable phenols), which account for an estimated 50% of the total phenols in P. oceanica leaves, is poorly understood.…”

“…Similarly, Agostini et al (1998) found higher concentrations (6 mg.g -1 ) in the apical parts and youngest leaves and lower concentrations in sheaths (0.1 mg.g -1 ). Also, in our study significant variation was observed between seasons; for example, phenolic levels were found to be higher in the January 2001 samples compared to the June 2000 samples.…”

“…However, as with other seagrasses, only a very limited number of studies deal with the role of phenolic and volatile compounds from Posidonia oceanica (Heglmeier & Zidorn, 2010) and Zostera marina (Short & Willie Echeverria, 1996). Only were investigated the impacts of interspecific competition (Dumay et al, 2004), nutrient variation, diseases (Vergeer & Develi, 1997) and grazing (Cannac et al, 2006), or general anthropization of water masses (Short & WyllieEcheverria, 1996, Agostini et al, 1998). …”

2018. Seagrass Posidonia oceanica (L.) Delile as a marine biomarker: a metabolomic and toxicological analysis. Ecosphere 9(3):e02054. 10. 1002/ecs2.2054 Abstract. A human-made environmental disaster due to the shipwrecked of Costa Concordia cruise vessel on the Tuscan Island of Giglio (Italy) coast and the possible pollutants release has been feared, so requiring the activation of removal operations and the monitoring of the marine environment. In the present study, the seagrass Posidonia oceanica (L.) Delile was used as a bioindicator for the impact of the Costa Concordia accident on the marine and coastal habitat. Different P. oceanica samples were collected in the shipwrecked site under different light conditions. Using high-performance thin-layer chromatography, metabolic analysis of the samples was carried out in order to highlight possible changes in the secondary metabolism due to the permanent shading and the presence of pollutant traces. Moreover, sample mutagenicity, as a consequence of the possible absorption of environmental toxicants leaked by the wreck, was assessed by the Ames test. The results highlighted the permanence of the Concordia-induced alteration in the plant secondary metabolites. However, absorption of chemical pollutants and carcinogens was not reported; this point was confirmed by the lack of mutagenic effects found for the samples tested. Our results clearly evidence that the environmental impact of Costa Concordia wreck and removal operations on P. oceanica was mainly due to the lack of light in the marine habitat. Present methodological approach, which combines metabolomic and genetic ecotoxicological analysis, could represent a suitable strategy to evaluate the impact of human disasters on the ecosystem and to monitor the environmental changes.
