"Marine monitoring along the eastern coastal area of the island of Lesvos, Greece in 2004 – MEDPOL III",

Abstract The present survey was conducted within the framework of MEDPOL Phase III (2004 – 2006). The purpose of the study is to provide recent information for the long-term monitoring of pollution trends in selected susceptible marine environments along the Mediterranean coastline. The study included the assessment of pollutants in abiotic components of the marine environment (seawater, sediment) as well as in selected marine organisms (M. barbatus and B. boops). The analysis showed low concentrations of phosphate, nitrite and ammonia and relatively high concentrations of silicate and nitrate in summer 2004. In autumn 2004 nitrite concentrations were rather low, whereas phosphate, silicate and ammonia were relatively high. Chlorophyll-a levels were high close to the Mytilini port which receives untreated sewage and low at the coastal stations in both sampling periods. Polyaromatic hydrocarbons were not detected in seawater from the port of Mytilini, with the exception of Fluοranthene in summer and Benzο-a-pyrene in autumn. Metal concentrations in sediment samples are similar to those reported for seawater bodies in Greece with no significant metal contamination. The highest metal concentrations were recorded at the station near the exit of the port of Mytilini. Statistical investigation of the data (normalization to Fe) showed a relatively mild contamination of the sediment at this station with respect to Cd, Cu, Hg, Zn and to an even lesser extent Pb. This situation may be attributed to the long-term discharge of untreated domestic effluents to the sea. Similar is the case with polyaromatic hydrocarbons, whereas halogenated hydrocarbons were not detected. Metal concentrations in the flesh of fish are similar in both species, and relatively low when compared to values in fish flesh from other areas either in Greece or in the Mediterranean, with the exception of Hg. Mercury concentrations are rather higher than those regularly reported in the literature, with the highest value found in the benthic species M. barbatus while a significantly lower value was found in the pelagic species B. bοοps. Polyaromatic and halogenated hydrocarbons were not at all detected in both pooled fish flesh samples. A general conclusion is that there is no evidence of substantial contamination in the marine environment of the eastern coast of Lesvos with respect to the pollutants analysed.
