dc.description.abstractWe discuss Al, Ag, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn contents in seagrass Posidonia oceanica rhizomes from the Balearic Archipelago for the last 3 decades. Time series of metal concentration in P. oceanica were measured by dating rhizomes using retrospective procedures. The highest concentrations of Al (174.73 μg g−1), Cd (3.56 μg g−1), Cr (1.34 μg g−1), Cu (32.15 μg g−1), Pb (8.51 μg g−1), and Zn (107.14 μg g−1) were measured in meadows located around the largest and most densely populated island (Mallorca Island). There was a general tendency for Ag concentration to decrease with time (up to 80% from 1990 to 2005 in sample from Mallorca Island), which could be attributed to a reduction of the anthropogenic sources. Nickel and Zn concentrations were the unique elements that showed a consistent temporal trend in all samples, increasing their concentrations since year 1996 at all studied stations; this trend matched with the time series of UV-absorbing aerosols particles in the air (i.e., aerosols index) over the Mediterranean region (r2: 0.78, p < 0.001 for Cabrera Island), suggesting that P. oceanica could be an efficient recorder of dust events. A comparison of enrichment factors in rhizomes relative to average crustal material indicates that suspended aerosol is also the most likely source for Cr and Fe to P. oceanica.-
dc.description.sponsorshipThis research was funded by the Balearic Government, as part of the assessment of Balearic Islands water masses within the European Water Frame Directive, the BBVA Foundation (BIOCON 04-091/05), the European project WISER, and the Cabiarca project (27/2007) funded by the CSIC. We thank R. Martínez, R. Santiago, and N. Garcias-Bonet for assistance with sample collection, and J. F. González (Serveis Cientificotècnics, UIB) for technical support with the ICP. J. Serón was supported by a Javier Benedí–IMEDEA scholarship.-
