Microplastics in wastewater outlets of Bandar Abbas city (Iran): A potential point source of microplastics into the Persian Gulf
AI summary Read the abstract
Wastewater discharged from Bandar Abbas City, Iran, into the Persian Gulf contained an average of 71 microplastic particles per 35 liters, with polyethylene and polypropylene as the most common types. This is the first study quantifying microplastic release from this region, establishing a baseline for monitoring plastic inputs into the Persian Gulf.
Wastewater discharge is considered to be a significant point source of microplastic (MPs) release into the marine environment. This study is the first attempt to quantify MPs released from the wastewater outfall from Bandar Abbas City into the Persian Gulf. Two wastewater discharge stations at Gursuzan and Suru were sampled. MPs were isolated by an oxidative procedure and subsequent density separation using ZnCl solution. The average MP concentration in wastewater and sludge were 70.66 (±14.12, SD) MP.35 L and 6070 (±807.25) MPs.kg, respectively at Confidence Level (CL) (95.0%). The most commonly recovered polymers were polyethylene (PE) and polypropylene (PP) in all size classes. Our findings provides a baseline of MP concentration in wastewater streams and slurry that is discharged from the Bandar Abbas wastewater treatment facility into the Persian Gulf. This highlights the need to undertake more studies at water treatment plants in the region for a realistic assessment of MP discharge into the Persian Gulf.

Microplastic pollution on the Persian Gulf shoreline: A case study of Bandar Abbas city, Hormozgan Province, Iran
AI summary Read the abstract
Beach microplastic abundance was measured across different land-use types along the Bandar Abbas coastline in Iran, finding an average of 3,252 ± 2,766 particles/m² with expanded polystyrene, PET, PP, and PE as dominant polymers, and significantly higher contamination near urbanized areas. The study demonstrates that land use intensity directly influences coastal microplastic deposition in the Persian Gulf.
Exploring the microplastic pollution: Unveiling origins and varieties in coastal sediments and waters of the Bushehr Province, Persian Gulf, Iran
AI summary Read the abstract
Researchers conducted a comprehensive survey of microplastic pollution in coastal sediments and waters along the Persian Gulf in Iran. They found microplastics at all sampling sites, with the highest concentrations near petrochemical facilities and urban centers, and fibers being the most common type. The study establishes baseline pollution data for the region and links contamination levels to specific human activities.
Occurrence and abundance of macro, meso and microplastics along the coasts of the Persian Gulf (case study: Bushehr Province coast)
AI summary Read the abstract
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.
Abundances and characteristics of microplastics in core sediments of the Persian Gulf coast, Iran
AI summary Read the abstract
Researchers sampled coastal sediments in Iran's Persian Gulf and found microplastics — including polystyrene, polyethylene, and PVC — at all six sites and at every depth down to 30 cm, averaging nearly 118 particles per kilogram of dry sediment. Fibers and fragments dominated, pointing to widespread plastic contamination from local waste mismanagement in this tidal ecosystem.
