Gheorghe Branch. High concentration of PAH’s compounds were recorded in Murighiol sediments and represents a significant pollution of the quality of sediment. The comparative analysis (physico-chemical determinations) of the quality characteristics of the Danube Delta aquatic ecosystem in these two years emphasized a dynamic character of the water quality that can determine an evolution into the unfavorable stages, which lead to worsen life conditions for aquatic organisms.en-USDanube DeltaWaterSedimentPhysico-chemical characterisationPollutionPAHArticle000257500700003
