Environmental quality assessment of the fish farms' impact in the Monastir Bay (eastern of Tunisia, Central Mediterranean): a benthic foraminiferal perspective.

Offshore fish farms have been active inside the Monastir Bay, Hammemet Gulf for over 10 years, but their environmental impact is still unknown. This study focuses on the evaluation of the fish farming activity impact in the Monastir Bay as revealed by geochemical and benthic foraminiferal data. Samples were collected around three fish cages at different water depths.

Assessment of organic and metallic contamination in the surface sediment of Monastir Bay (Eastern Tunisia): Spatial distribution, potential sources, and ecological risk assessment.

To investigate the current environment status in Monastir Bay (Tunisia), surface sediments from 32 stations were assessed for heavy metal and organic matter concentrations, and the results were compared with values of natural metal content, marine sediment quality standards, and other results concerning sediments from other Mediterranean coasts. The study of their spatial distributions refined by complementary approaches, including potential ecological risks determined through the enrichment factor, geo-accumulation index, contamination factor, potential ecological risk index, pollution load index, and principal component analysis, showed a significant impact of multiple anthropogenic sources. Moderate pollution of sediments, particularly by Ni and Cu, was also observed.

Natural and anthropogenic particulate-bound aliphatic and polycyclic aromatic hydrocarbons in surface waters of the Gulf of Gabès (Tunisia, southern Mediterranean Sea).

Particulate-bound aliphatic and polycyclic aromatic hydrocarbons (AHs and PAHs) were investigated in the surface waters of the Gulf of Gabès (Tunisia, southern Mediterranean Sea). Samples were collected off the Sfax and Gabès-Ghannouch coasts. Concentrations in total resolved n-alkanes ranged from 0.
