Distribution of Polycyclic Aromatic Hydrocarbons (PAHs) in M’Badon Bay (Ebrie Lagoon, Abidjan-Cote d’Ivoire)

Pollution of the environment by polycyclic aromatic hydrocarbons (PAHs) is great concern because their persistence, toxicity, mutagenic and carcinogenic nature. The distribution 8 PAHs in water surface sediment from M’Badon Bay (Ebrie Lagoon, Côte d’Ivoire) was investigated using high performance liquid chromatography (HPLC). results showed that mean PAH concentrations ranged 0.08 to 2.70 µg/L waters 0.37 25.9 µg/kg sediments. It found pyrene indeno[1,2,3-cd]pyrene have highest (12.35 4.69µg/L, respectively) while only sediments (154.1 µg/kg). Furthermore, benzo[a]pyrene are frequently detected during dry, wet, flood seasons. In addition, wet season for both Diagnostic ratio revealed a petrogenic origin contamination bay equivalent toxicity indicated low living organisms. Also, benzo[k]fluoranthene exceeded some cases European Union Maximum Allowable (0.1 µg/L). this study suggest may result cancer risks local communities who use it fishing domestic purposes.
