Article Synopsis
- A study was conducted to assess PAH contamination in sediments from the Bizerte Lagoon in northern Tunisia, where 18 surface sediment samples were analyzed for 14 harmful PAH compounds.
- The concentration of PAHs ranged from 16.9 to 394.1 ng g(-1) dry weight, with an average of 85.5 ng g(-1) dry weight, indicating low to moderate levels compared to other global locations.
- The main sources of PAHs were identified as pyrolytic origins, and based on sediment quality guidelines, the PAH levels in the lagoon are unlikely to cause harmful biological effects, with toxicity equivalent values averaging 10.6 ng g(-1) dry weight.
Despite their low water solubility, hydrophobic pollutants are widespread in the aquatic environment and could represent a threat for living organisms. EU regulations on chemicals require accurate and reliable data on chemical toxicity. Current normalised fish toxicity assays, in particular those advocated by OECD guidelines, do not allow reliable toxicity assessment of hydrophobic compounds due to their low water solubility.
