Levels and spatial distribution of perfluorinated compounds (PFCs) in superficial sediments from the marine reserves of the Tuscan Archipelago National Park (Italy)
Surface sediments from marine reserves of the Tuscan Archipelago National Park (Italy), including remote islands not directly affected by anthropogenic influences, were analyzed for two dominant perfluorinated compounds (PFCs), namely perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), using LC-ESI-MS/MS. The concentrations of PFOS were low, with medians ranging from 0.25 to 1.50. ng/g dry wt, whereas PFOA was always below the detection limit of 0.1. ng/g dry wt. The present paper can be considered a baseline study useful in future environmental monitoring programs. © 2013 Elsevier Ltd

The European lancelet Branchiostoma lanceolatum (Pallas) as an indicator of environmental quality of Tuscan Archipelago (Western Mediterranean Sea)
In June 2004 we found adults of Branchiostoma lanceolatum (Pallas, 1774; Cephalochordata) in sediment
sampled within the integral reserve zone on the western side of Capraia island. The collecting site was located at 33m depth in front of Punta del Fondo, by an extended Posidonia bed. The rippled substrate was dominated by coarse to very coarse sand (78.61%) while the silt-clay fraction accounted for less than 3%. The organic contamination analysis of the sediment gave results typical for unpolluted areas in the Mediterranean: total organic carbon 1.2%; 16 US-EPA PAHs 1.57 ng/g d.w., with a predominance of high molecular weight compounds; total PCBs 0.36 ng/g d.w., with a prevalence of higher chlorinated congeners; PBDE 16.26 pg/g d.w.; HCB and pp’-DDE below the limits of detection. Once abundant along
the Italian coasts, B. lanceolatum is nowrare and apparently confined to marine protected areas. In Tuscany,
the species was known so far only from the Meloria Shoals. Most data in the literature suggest that its demise is related to the change in texture and eutrophication of the coastal sediments. Future studies should investigate the species’ tolerance to chemical pollutant
