The purpose of this study was to determine the variation of concentrations and distribution of PAHs in the sediments of the Gela coastal area (Italy) caused by the construction of an underwater pipeline connecting Libya to Sicilian coast. The receiving terminal of offshore pipeline, crossing the Mediterranean Sea, 516 Km long, up to 1127 meters deep, is located in Gela (Sicily, Italy). No bibliographic data regarding hydrocarbons are available for this area. In their paper the authors report the results of analysis on the water and organic along PAHs.The total concentrations of 16 PAHs in the sediments, analyzed during five surveys, ranged from 2.4 to 434 mu g/kg of dry weight. The highest concentrations of total PAHs were found in sediments during the monitoring campaign immediately following the laying of the pipeline. A progressive decrease during the subsequent surveys was observed: The found concentrations was in the direction of restoring the initial situation. Highest levels of PAHs concentration have been often observed in sample stations endowed with highest organic matter content.
