Microplastic (MP) Pollution in Sidi Youssef Harbor of the Kerkennah Islands, Sfax (Tunisia)
AI summary Read the abstract
Microplastic pollution was documented in the harbor sediments of Kerkennah Islands in Tunisia, driven by abandoned fishing gear and plastic litter, with contamination threatening a coastal marine ecosystem important for local fisheries. The findings add to growing evidence that Mediterranean harbor environments are microplastic hotspots with direct implications for seafood quality and coastal community livelihoods.
Microplastics (MPs) (<5 mm) are emerging pollutants that have attracted widespread environmental concerns about their negative effects on the marine ecosystems. The harbor area of Sidi Youssef in Kerkennah Islands is threatened by the abandoned plastic...

Characterization and distribution of microplastics on the beaches of Southern Tunisia: a case study of the Island of Djerba
AI summary Read the abstract
Researchers analyzed microplastics in sediments from eight beaches on Djerba Island, Tunisia, finding concentrations up to 127 particles per kilogram with the highest accumulation in dune zones, and polyethylene, polypropylene, and polystyrene as the dominant polymers. The spatial variation linked to tourism, fishing, and urban runoff illustrates how local human activities shape microplastic distribution in coastal Mediterranean environments.
The First Evaluation of Microplastics in Sediments from the Complex Lagoon-Channel of Bizerte (Northern Tunisia)
AI summary Read the abstract
Researchers conducted the first survey of microplastics in sediments from the Bizerte lagoon-channel in Tunisia, finding concentrations of 3–18 items per gram dominated by fibers from fishing and urban discharge, identifying this coastal site as a microplastic hotspot with implications for seafood safety.
Assessing microplastic presence and distribution in sandy beaches: a case study of the Gulf of Tunis coastline
AI summary Read the abstract
A seasonal survey of Gulf of Tunis beach sediments found microplastic concentrations ranging from 109 particles/kg in summer to 531 particles/kg in winter, with polyethylene and polypropylene as dominant polymers and higher accumulation in upper beach and dune zones than in wave-exposed foreshores. These findings reveal how beach morphology and seasonal dynamics shape microplastic distribution at a major entry point for litter into the Mediterranean marine system.
Microalgae colonization and trace element accumulation on the plastisphere of marine plastic debris in Monastir Bay (Eastern Tunisia)
AI summary Read the abstract
Researchers characterized epiplastic microalgal communities and trace metal accumulation on plastic debris in Monastir Bay, Tunisia, finding that potentially harmful algae — including toxin-associated diatoms and cyanobacteria — were more abundant on plastic surfaces than in surrounding water, and that the plastisphere concentrated heavy metals like Pb and Cu at far higher levels than adjacent sediments.
