Abstract
Concentration of ten polycyclic aromatic hydrocarbon (PAH) compounds were determined in liver of four fish species from different trophic levels (Aurigequula fasciata, omnivore; Alepes djedaba, carnivore; Liza abu and Sardinella albella, phytoplanktivores). In all the species, similar distributions were observed in which pyrene predominated and followed by naphthalene and acenaphthylene. L. abu accumulated the highest concentration of ΣPAH, followed by S. albella, A. fasciata, and A. djedaba. No correlation between PAH content in fish liver and fish size has been found at the level of individual compounds, except for benzo[a]pyrene (p < 0.01, r = -0.704). Female fish exhibited significantly lower mean ΣPAH concentrations than male in all the species, except for L. abu.
