Occurrence and characteristics of microplastics in surface water and sediment of Zayandeh-rud river, Iran
This study surveyed microplastic pollution in the Zayandeh-rud River, the most important river in central Iran, sampling both water and sediment at 19 locations. Researchers found microplastics at every site, with fibers being the most common shape and concentrations higher in sediment than in surface water. Areas near urban centers and industrial zones showed the highest contamination levels, pointing to human activity as a major source.
Partial and Temporal Variations in Concentration of Micro Plastic in Drinking Water of Al-Hilla River
This study measured microplastic concentrations in drinking water from the Al-Hilla River in Iraq, finding contamination across multiple sampling locations and time periods. The presence of microplastics in tap water raises concerns about daily human ingestion through drinking water.
Occurrence, distribution and sources of microplastics in beach sediments of Miri coast, NW Borneo
Researchers characterized microplastic pollution in the surface sediments of 10 European rivers, detecting particles at all sites with concentrations ranging from 14 to 895 particles per kilogram of dry sediment. Urban rivers showed the highest contamination levels.
Assessment of Microplastic Pollution in Sediments from Khor Al-Zubair, North-West of Arabian Gulf
Researchers collected sediment samples from three sites in Khor Al-Zubair in the northwestern Arabian Gulf, Iraq, and confirmed the presence of microplastic fragments and fibers composed primarily of polyethylene and polypropylene. Concentrations were highest near industrial areas, pointing to sewage discharge and industrial waste as primary sources. This short study provides one of the first data points on microplastic pollution in Iraqi marine waters, a region that has been largely overlooked in global monitoring efforts. Baseline data like this are essential for future regional management strategies.
Contamination and characterization of microplastics in different sediments of the river estuaries (the inner Gulf of Thailand)
Researchers measured microplastic contamination in river estuary sediments in the inner Gulf of Thailand, finding widespread contamination at all sites. The study characterizes the types and abundance of microplastics in a highly trafficked coastal region of Southeast Asia.
Microplastic pollution in sediments in the urban section of the Qara Su River, Iran
Researchers sampled 15 sites along the Qara Su River in Iran and found microplastics in all sediment samples, with fibers making up 53% of particles and 92% of pieces smaller than 5 millimeters — the first microplastic survey of this river and a sign that urban wastewater treatment is not removing these pollutants effectively.
Exploring the microplastic pollution: Unveiling origins and varieties in coastal sediments and waters of the Bushehr Province, Persian Gulf, Iran
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.
