Distribution and characterization of microplastics in marine sediments from al-hoceima bay (southwestern mediterranean, morocco)
AI summary Read the abstract
Researchers examined the presence and distribution of microplastics in marine sediments from nine stations in Al-Hoceima Bay on the Moroccan Mediterranean coast, sampling with Van Veen grabs during 2019, 2020, and 2021 and analyzing particles via optical microscopy. They identified fibers, fragments, foams, and films as the dominant microplastic types, documenting pollution levels in a biodiverse but increasingly anthropogenically pressured coastal zone.
The Moroccan Mediterranean coast is known for its richness and biological diversity. However, it is increasingly threatened by degradation due to the progressive anthropization of coastal zones and the maritime traffic crossing the Strait of Gibraltar. This makes the Moroccan Mediterranean coast particularly vulnerable to marine pollution, especially plastic waste. Al-Hoceima Bay is situated in the central Rif region on the Moroccan Mediterranean coast. Currently, it faces various anthropogenic pressures due to its geographical location . These pressures often result in pollution. In this research project, we examined the presence of microplastics in the sediments of Al Hoceima Bay. We collected samples from nine different stations during the years 2019, 2020, and 2021 using a Van Veen grab. The microplastics were then analyzed and quantified using an optical microscope. Our results revealed that fibers, fragments, foams, and films were the main types of microplastics present. The microplastics ranged in size from 0.1 to 5 mm, with particles sized 1-2 mm being particularly prevalent, accounting for 44.82 Also see: https://micro2024.sciencesconf.org/558725/document

Presence, Spatial Distribution, and Characteristics of Microplastics in Beach Sediments Along the Northwestern Moroccan Mediterranean Coast
AI summary Read the abstract
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.
