Assessment of the total microplastic stock in the eastern red sea
Researchers assessed the total microplastic stock in the eastern Red Sea by collecting sediment and water column samples from the Farasan area, addressing the limited attention this region has received despite rapid urbanization, tourism development, and critical shipping routes. The study characterized microplastic levels, distribution patterns, and polymer types in a unique marine ecosystem ahead of new international plastic pollution regulations.
Assessment of the total microplastic stock in the eastern red sea
Researchers assessed microplastic distribution in the Eastern Red Sea from the Farasan Islands to the Gulf of Aqaba during the 2022 Red Sea Decade Expedition, collecting 60 sediment core samples via remotely operated vehicle and 145 water column samples across bathypelagic, mesopelagic, and epipelagic layers. The study addressed a major data gap for this underinvestigated but ecologically significant region with rapidly expanding urbanisation and tourism.
Plastic pollution in the Red Sea: A comprehensive analysis from the air to the seafloor
Researchers conducted a comprehensive assessment of plastic pollution across multiple environmental compartments of the Red Sea — including surface water, the water column, and deep-sea sediments — finding that deep-sea sediments hold up to 80% of microplastics in the basin and that subsurface water layers act as significant reservoirs, complicating global microplastic load estimates based solely on surface water data.
Characterization of Microplastic Pollution Along the Red Sea Coast of Jeddah, Saudi Arabia
Researchers conducted a detailed physical, chemical, and morphological analysis of microplastics collected from the Red Sea coast near Jeddah, Saudi Arabia, using a suite of advanced techniques including electron microscopy, Raman spectroscopy, and atomic force microscopy. They found that particles were predominantly weathered polyethylene terephthalate (PET), showing signs of significant degradation from sun, salt, and wave exposure. The study identifies urban runoff, coastal activities, and industrial discharge as likely sources, providing the first detailed characterization of microplastics in this unique marine environment.
Microplastics Pollution in Aquatic Environment: A Review of Abundance, Distribution, and Composition in the Egyptian Coastal Waters
This review compiles data on microplastic pollution across Egypt's Mediterranean coast, the Nile River, and the Red Sea, all of which face significant plastic contamination. Researchers found that the Mediterranean is a global hotspot for marine plastic accumulation, while the Nile acts as a major conduit for plastics entering the eastern Mediterranean basin. The study calls for more systematic monitoring to understand the full scope of microplastic pollution in Egyptian waters.
Microplastics in sediments and fish from the Red Sea coast at Jeddah (Saudi Arabia)
Microplastics were found in nearshore sediments at all sampled stations along the Jeddah coast of Saudi Arabia's Red Sea, and in about half of 140 sampled fish. The findings demonstrate that even the Red Sea — an important but less-studied ocean region — is experiencing widespread microplastic contamination.
Microplastic Composition and Distribution Across the Pelagic and Benthic Zones of the Jordanian Gulf of Aqaba, Red Sea
Researchers sampled microplastics at multiple depths in the Gulf of Aqaba — from surface waters down to 840-meter-deep seafloor sediments — and found that particle size decreased with depth while fiber shapes dominated in open water and fragments accumulated on the seafloor. Concentrations reached nearly 7 particles per liter at the surface and 2,900 particles per kilogram of sediment. The study provides a baseline for monitoring this relatively understudied part of the Red Sea, which is important for regional fisheries and coral reef health.
