Occurrence and spatial distribution of microplastics in the intertidal sediments along the Oman Sea

This study documented microplastic contamination in intertidal sediments along seven locations on the Oman Sea coast, finding average levels of about 315 particles per kilogram of dry sediment. Fragments and fibers dominated, with polypropylene as the most common polymer identified by Raman spectroscopy. The results confirm that microplastic pollution has reached the Oman Sea coastline and call for regional regulations to reduce plastic inputs into this relatively understudied marine environment.

Occurrence and abundance of macro, meso and microplastics along the coasts of the Persian Gulf (case study: Bushehr Province coast)

This survey of 17 coastal stations in Iran's Bushehr Province on the Persian Gulf documented widespread plastic pollution at macro, meso, and microplastic scales, with fibers making up the majority and fragments under 500 micrometers being most common. Polyethylene, polystyrene, PET, and nylon were the dominant polymer types identified by infrared analysis. The Persian Gulf is a semi-enclosed, heavily industrialized sea, and this data establishes baseline contamination levels needed to track how pollution changes over time.

Microplastics in the surface seawaters of Chabahar Bay, Gulf of Oman (Makran Coasts)

Researchers conducted the first survey of microplastic pollution in the surface waters of Chabahar Bay in the Gulf of Oman. They found microplastic densities ranging up to 1.14 particles per cubic meter, with fibers being the most common shape and polyethylene and polypropylene the dominant polymer types. The highest concentrations were found near populated areas, suggesting that human activity is a major source of microplastic contamination in this coastal region.

Microplastics contamination in molluscs from the northern part of the Persian Gulf

Researchers analyzed microplastic contamination in five species of mollusks from the northern Persian Gulf, including both gastropods and bivalves with different feeding strategies. They found microplastics in all species, with concentrations ranging from 0.2 to 21 particles per gram of soft tissue, and fibers were the most common type. The study indicates that microplastic contamination is widespread in Persian Gulf seafood and that filter-feeding organisms tend to accumulate more particles.

Assessing microplastic pollution in coastal sediments of the Oman Sea: ecological risk and land-use linkages

A survey of coastal sediments along the Oman Sea shoreline near Chabahar, Iran, found microplastic concentrations varied dramatically by land use—commercial port and market areas had up to 161 particles per 100 grams of sediment, while remote mangrove forests had as few as 6 particles per 100 grams. Fibers and fragments of polyethylene, polypropylene, and nylon were most common. The clear gradient from urbanized to natural areas confirms that human activity is the primary driver of coastal microplastic accumulation, and that mangrove ecosystems—despite their ecological importance—are not immune to plastic contamination.
