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.
Differences in distribution and characteristics of microplastics in sediments of the south-eastern part of the Gulf of Trieste
Researchers investigated microplastic distribution and characteristics in sediments across the south-eastern Gulf of Trieste, a semi-enclosed sea with limited prior research. The study aimed to identify sources and spatial patterns of microplastic accumulation in this geomorphologically distinct coastal area.
Seasonal and spatial distribution of microplastics in sediments by FTIR imaging throughout a continuum lake - lagoon- beach from the Tunisian coast

A study at Mahitam Island in Lampung Bay, Indonesia, identified microplastics in both seawater and sediment samples using Fourier-transform infrared spectroscopy. Fibers and fragments were the most common types found, indicating that plastic pollution has reached this coastal area.
Microplastics and polycyclic aromatic hydrocarbons (PAHs) in Xiamen coastal areas: Implications for anthropogenic impacts
Researchers measured both microplastic abundance and polycyclic aromatic hydrocarbon (PAH) concentrations in surface water and sediments of Xiamen coastal areas in southeast China. The study found that microplastic distribution correlated with urbanization and industrial activity patterns, suggesting that anthropogenic inputs drive co-contamination of coastal environments with both microplastics and chemical pollutants.
Small microplastics (<100 μm), plasticizers and additives in seawater and sediments: Oleo-extraction, purification, quantification, and polymer characterization using Micro-FTIR
Small microplastics below 100 micrometers, plasticizers, and plastic additives were simultaneously quantified in seawater and sediments from Italian transitional water bodies using oleo-extraction and micro-FTIR, revealing that sub-100-micrometer particles and chemical additives represent a substantial and understudied component of total microplastic contamination.
