Occurrence of Polycyclic aromatic hydrocarbons (PAHs) in mullet (Liza aurata) from Bizerte and Ghar El Melh Lagoons (Tunisia) and associated human health risk assessment

Article scientifique 2022 Anglais

Résumé

Abstract There is a scarcity of information on the presence of polycyclic aromatic hydrocarbons in biota from Tunisian coastal ecosystems. To our knowledge, this is the first work to report these chemicals in the biota of Ghar El Melh Lagoon. In Liza aurata muscle from the Bizerte and Ghar El Melh Lagoons (Tunisia), levels of 15 priority polycyclic aromatic hydrocarbons were measured. Total PAH levels in mullet from the Bizerte and Ghar El Melh Lagoons were comparable to or lower than those found in other fish specimens from around the globe. The nature of the detected chemicals reveals petrogenic and pyrolytic anthropogenic contamination in both studied lagoons. The human health threat caused by mullet consumption was assessed, and it was observed that PAH intakes pose no threat to the local population's health.
