Ecophysiological responses of Mediterranean pines to simulated sea aerosol polluted with an anionic surfactant: prospects for biomonitoring

Abstract: -Sea aerosol may contain surfactants as pollutants. We examined ecophysiological mechanisms involved in the sensitivity of three Mediterranean pines to five spray treatments with sea water including an anionic surfactant, 5 to 500 mg/L dioctyl sodium sulphosuccinate. Despite the reduction of surfactant in sea aerosol over the past 20 years, Mediterranean pinewoods are still at risk for surfactant pollution, since concentrations in the field reach the visible injury threshold here recorded, i.e. 2 mg/L surfacta… Show more

“…(For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.) Wettability assays yielded contact angles of 60.7 ± 2.3 • for P. pinaster and 54.6 ± 3.9 • for P. pinea, similar to those found by Rettori et al (2005). This means that P. pinea needles are slightly more wettable, hence favoring the wet deposition of atmospheric pollutants.…”

“…The pine forest is part of the ''Tomboli di Cecina'' Natural Reserve; it was planted for the first time in 1839 after a century of land reclamation efforts started in 1740 (Repetti, 1833;Gatteschi and Milanese, 1990). The forest is homogenous for seed origin and management (Bassi, 1927;Giordano, 1947;Baroni, 1973), but it faces coastal sectors with different erosion regimes.…”

“…According to Raddi et al (2009), growth decline in Pinus pinea on the eroded coastal dunes in Italy may be attributed to greater exposure of the crowns to salty winds and surfactants and increased salinity of the water table. On the other hand, Pinus pinea is highly sensitive to exposure both to sea spray and to surfactants in marine aerosols (Raventos et al, 2001;Rettori et al, 2005). In the Mezel Belgacem forest, El Ayeb et al (2004) noted increased Na + concentration in leaf tissue when trees were closer to the shoreline (Na + increased from 0.54 to 0.62% in Acacia and from 0.39 to 2.3% in Eucalyptus).…”
