Presence, Spatial Distribution, and Characteristics of Microplastics in Beach Sediments Along the Northwestern Moroccan Mediterranean Coast
Researchers surveyed fourteen beaches along the northwestern Moroccan Mediterranean coast and found microplastics in every sediment sample, averaging about 59 particles per kilogram of dry sand. Fibers were the dominant shape at nearly 78%, with tourism, fishing, and wastewater discharges identified as the most likely pollution sources. The findings indicate moderate but widespread microplastic contamination along this coastline.

Microplastic surveys of seven beaches on Morocco's central Atlantic coast found densities ranging from 7,680 to 34,200 particles/kg -- higher than many global reports -- with fibers (73%) and polyethylene (59%) dominating, providing baseline data for this previously unstudied coastline.
Seasonal variation of microplastics density in Algerian surface waters (South-Western Mediterranean Sea)
Researchers monitored seasonal variation in microplastic density in Algerian surface waters of the south-western Mediterranean Sea, documenting temporal patterns in microplastic concentrations in an understudied region of the Mediterranean.
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.
Microplastics pollution in sediments of Moroccan urban beaches: The Taghazout coast as a case study
This study analyzed microplastics in beach sediments at Taghazout coast, Morocco over two years, finding average densities of 915 particles per kilogram in 2018 and 1,448 particles per kilogram in 2019. Higher concentrations were found near beachgoer facilities in the southern part of the study area.
Beached microplastics in the Northwestern Mediterranean Sea
Researchers investigated microplastic occurrence on two beaches in the Northwestern Mediterranean Gulf of Lion, finding significant concentrations of fragments and pellets in beach sediments with notable variation between beach zones and sampling periods over a one-month interval.
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.

Scientists found microplastics in every fish and mussel sample examined from the Algerian Mediterranean coast, with six common plastic types identified including polypropylene and polyethylene. The contaminated species are widely consumed by local populations.
