Geochemical and sedimentological assessment of the prokopos coastal lagoon sediments, mediterranean sea Western Greece

摘要: In order to evaluate the environmental status of an internationally protected shallow coastal lagoon, sedimentological and geochemical parameters were used for the Prokopos lagoon sediments, which is located at Western Greece. Six gravity cores with sediment depth up to 0.70 m interval were collected and analyzed for K2O, CaO, Na2O, MgO Fe2O3, MnO, Al2O3, P2O5, TOC, V, Cr, Zn, Ni, Cu, Cd, Pb. In addition the clay, sand and silt content were determined and the mean size (Mz), sorting (σ), skewness (Sk) and kurtosis (KG) values were deduced. The lagoon's sediments are composed mainly of fine silt to medium sand. The clay content of the samples ranges from 0.76% to 6.73% and the average values of the silt and sand content are 50.20% and 42.56% respectively. The enrichment factor-EF values calculated for Cd showing significant enrichment in P1, P2 and P4 sampling sites. The contamination factor …
