Estimation of Polycyclic Aromatic Hydrocarbons (PAHs) in Some Fishes of Shatt Al-Arab River-Iraq
Abstract
Levels of sixteen polycyclic aromatic hydrocarbons (PAHs) in six edible tissues of selected frequently-consumed fish collected from Shatt Al-Arab river, namely, Luciobarbus xanthopterus , Ctenophyngodon idella, Cyprinus carpio, Tilapia zillii, Palaniza abu and Leuciscus vorax were investigated in 2015. High Pressure Liquid Chromatography (HPLC) analysis was employed for determination of PAHs. Total PAHs in the samples ranged from 0.02 ng/g dry weights in Cy. carpio to 3.34 ng/g dry weights in Le. vorax . Some ratios were calculated to evaluate the sources of these compounds in the area. The results showed that there was pyrolytic and petrogonic sources.Low molecular weight (LMW) PAHs was the predominant compounds, suggesting the gill-water transfer might be the major exposure route for PAHs in the studied fish species.
