Assessment of Dissolved and Particulate Polycyclic Aromatic Hydrocarbons (PAHs) and their Nitro Derivatives (NPAHs) in the Mediterranean Sea Surface Waters along Alexandria Coast
Hossam F. Nassar

Abstract:
Background and Objective: Polycyclic aromatic hydrocarbons (PAHs) and their derivatives are widely diffused organic pollutant to the environment because of their semi-volatile characteristics. These pollutants are carcinogenic and/or mutagenic and have to be intensively regulated and monitored. In this research studied the dissolved and particulate PAH and NPAHs (nitro-polycyclic aromatic hydrocarbons) concentrations in the Mediterranean sea water along Alexandria coast. Materials and Methods: Samples were collected from three different sites (Alex1, Alex2 and Alex3) representing different activities in the sampling area. HPLC with fluorescence detection was used for PAHs detection, whereas, HPLC with chemiluminescence detection was used for NPAHs detection. Results: The measured concentration levels of dissolved PAHs and NPAHs were ranged from (230.5-704.1) ng L–1, respectively, while those for particulate PAHs and NPAHs were ranged from (79.1-288.5) ng L–1, respectively. Molecular diagnostic ratios were calculated to identify the sources of emissions of such compounds. Results indicated a major contributor of the pyrolytic and sewage discharge contamination particularly at sites (Alex2 and Alex3) with a mixed petrogenic pattern from urban runoff inputs and frequent oil spills at site (Alex1). Conclusion: PAHs and NPAHs total concentration levels at the three sampling stations in the Mediterranean Sea along Alexandria coast followed the order: Alex1> Alex2> Alex3.
