Abstract

Quantitative Analysis and Risk Assessment of Polycyclic Aromatic Hydrocarbons (Pahs) in Marine Organisms from Moroccan Coastal

Author(s): Fatima Zahra Ndadani, Fouzia Zkhiri, Abderrazzak Rachidi

Fishery products play an increasingly vital role in meeting nutritional needs. They represent valuable sources of proteins and minerals beneficial to health. Polycyclic Aromatic Hydrocarbons (PAHs) are among the toxic chemical contaminants that accumulate in marine organisms. In this context that this study aims to assess specifically the pollutants that can impair the quality and safety of fish products in Morocco. Four elements of PAHs were studied in order to investigate the direct impact of sampling areas and species on PAH levels in the marine environment. The PAHs were assayed by Gas Chromatography Coupled to a Mass Spectrometer (GC/MS). The method of calculation of the reports and the statistical analysis made it possible to determine the origin of the contamination of the fishes and the factors that give rise to their spatial evolution. The study showed that the cities of Tetouan, Eljadida, Dakhla, Safi, Essaouira and Kenitra are relatively the most contaminated by PAHs and are the most threatened because of the developed industry in these regions. Nevertheless, the grade of PAH studies and the level of contamination remain below the limits recommended by European Regulation.
