| dc.description.abstract | With the aim of evaluating the levels of contamination of the superficial sediment in the coastal fringe of the El Djamila bay and the burial capacity of PAHs; a study has been established. The sediment matrix was exposed to two types of analysis: a granulometric analysis using the dry sieving method, simultaneously carried out with an estimation of the moisture content and organic matter. The second is about analyzing the extracted PAHs with the Ultraviolet Fluorescence Spectroscopy method. The results allow identifying the textural classes varying from silt to coarse sand. The mean values of the retention capacity were 15.27% and 3.88%, and the PAHs concentrations were 13.31±6.72 µg/g and 2.74±1.64 µg/g for the stations of the harbor and the beaches respectively. High concentrations exceeding the norms were observed, yet expected given quantities of discharged effluents in the area. In addition, a strong positive correlation was found between the burial capacity, the organic matter percentage, and the PAHs concentration. | |
