Summary

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.

Polymers

Current study aimed to evaluate the microplastics abundance in the surface waters of Chabahar Bay for the first time. 21 neuston net water samples were collected from 7 stations. Microplastics were visually counted by stereomicroscope, sorted into 4 size categories, 4 shape categories, and identified by ATR-FTIR spectroscopy. Density of microplastics varied from 0.07 ± 0.03 to 1.14 ± 0.27 with an average density of 0.49 ± 0.43 particle·m. Microplastics were mostly found in the shape of fibers. 69% of analyzed particles were polyethylene and polypropylene. Main colors of the collected microplastics were white, blue and red. The results showed that the largest number of microplastics was found at station near populated area. Therefore, it can be concluded that, there is a pressing-need to investigate the distribution of microplastics in sediments and biota of this Bay as well as their effects on marine life and human health.

Microplastic pollution in the littoral sediments of the northern part of the Oman Sea

Researchers conducted the first assessment of microplastic pollution in littoral sediments of the northern Oman Sea, finding MPs at all eight sampling stations at abundances of 138.3 to 930.3 particles per kg. Polyethylene was the dominant polymer, with fibers and fragments the most common shapes, establishing a baseline and underscoring the need for improved waste management and environmental protection in the region.

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.

Microplastic contaminants in the sediment of the north coasts of the Persian Gulf and Gulf of Oman

Researchers characterized microplastic abundances and properties in coastal sediments of the Persian Gulf and Gulf of Oman, finding concentrations ranging from 10 to 45 particles per kilogram with an average of 655 pieces per kilogram and a predominance of black fibers and high-density polymers. Raman analysis confirmed polymer identities and revealed a negative depth gradient with decreasing MP concentrations from coastal to deeper waters.

Neustonic microplastic pollution in the Persian Gulf

Researchers conducted the first comprehensive survey of microplastic pollution in the surface waters of the Persian Gulf, sampling 15 stations. They found microplastics at every station, with fibers being the most common shape and polyethylene and polypropylene making up about 76% of all particles identified. The study confirms widespread microplastic contamination in the Persian Gulf and calls for further investigation into the effects on marine life and human health in the region.
