CLAIM research topic: Insight into MPs contamination levels in water and biota samples obtained in the Gulf of Gabes

A recently published article in CLAIM’s research topic in Frontiers in Marine Science journal investigates the distribution, abundance, size, and polymer type of microplastics in surface water samples collected with a Manta net (200 μm mesh size) and in 118 marine specimens of commercial interests CLAIM’s sampling campaigns in the Gulf of Gabes (Southern Mediterranean Sea) during spring and autumn 2019. Specimens fishes, crustaceans, and mollusks.

The authors of the article, amongst whom CLAIM researchers from INSTM, CNR, University of Tunis, used a 3D hydrodynamic and Tracking Model to identify dispersal and transport pathways of the floating plastics.

Their findings show that there is a seasonal variability in MPs distribution between the first (spring) and the second campaign (аutumn). Also, despite the high levels of MPs discovered in surface water samples, there was a low overall frequency of ingestion across the examined species, with a maximum of 20% of individuals (in Scomber scombrus) having eaten MPs.

This study adds to people’s understanding of MPs contamination levels in water and biota samples obtained in the Gulf of Gabes, an area of considerable interest for its biological resources but one that has received little research.
