This study assessed microplastic abundance and polymer composition in sediments along the Gulf of Suez shores, identifying 268 microplastic particles with an average of 204.3 particles per kilogram of dry sediment, reflecting contamination from the region's intense shipping and industrial activities.
A multi-compartment assessment from surface waters to sediments of microplastic pollution in the southern Mediterranean sea: A case study of BouIsmail Bay, Algeria
Researchers investigated the spatial distribution, abundance, and characteristics of microplastics in surface water and seafloor sediments at multiple coastal and offshore stations in BouIsmail Bay on Algeria's southern Mediterranean coast during summer 2023, using KOH digestion and density separation for extraction. The multi-compartment assessment found polyethylene, polypropylene, and polystyrene as the most common polymers with fragments dominant in surface waters and fibers dominant in sediments, providing new baseline data for the under-characterised southern Mediterranean.
Microplastic Contaminants in the Sediment of the East Coast of Saudi Arabia
Researchers conducted the first measurement of microplastic contamination in sediments along four beaches on Saudi Arabia's east coast, finding 586 microplastic particles with fibers being the dominant shape (96%) and polyethylene terephthalate the most common polymer type, with abundance varying between tidal zones.
Assessment of microplastic pollution: distribution, composition, and sources in the El-Mellah (Algeria) and Bizerte (Tunisia) Mediterranean lagoons

Abundance and distribution of microplastics on sandy beaches of the eastern Moroccan Mediterranean coast
Researchers surveyed 19 sandy beaches along the eastern Moroccan Mediterranean coast and found microplastic concentrations ranging from 40 to 230 particles per kilogram of sand. Fibers were the most common shape, making up about 75 percent of all particles found, with polyethylene, polystyrene, and polypropylene as the dominant polymer types. The findings indicate a moderate level of microplastic contamination along this stretch of coastline.
