Researchers measured microplastic concentrations in the Godavari River in India, finding an average of 3.9 particles per liter across six sites, with fibers making up over 80% of particles and polypropylene and polyethylene being the most common polymer types. Urban areas had higher concentrations, and the presence of these plastics in a major river system poses risks to agriculture and human health through contaminated water and food sources.
Identification and Quantification of Microplastic Pollution in Water Samples and Four Species of Fish from the Mississippi River
Microplastics were found in water samples and in four fish species from the Mississippi River, the largest North American river draining a densely populated watershed. The findings confirm that one of the world's major river systems is contaminated with microplastics, which are likely entering the Gulf of Mexico.

This study assessed microplastic contamination in tap water distributed to homes in Mosul City, Iraq, finding plastic particles in drinking water. The presence of microplastics in tap water raises concerns about daily human exposure through drinking water consumption.
Prevalence of Microplastic Pollution in Freshwater Ecosystem: A Case Study of Thal Canal
Researchers surveyed microplastic contamination in a freshwater ecosystem in a case study region, measuring particle concentrations and types in water and sediment samples across multiple sites. Microplastics were detected at all sampling locations with higher concentrations near urban areas, and fibres and fragments were the dominant particle morphologies found.
Investigation of microplastic pollution in Torghabeh River sediments, northeast of Iran
Researchers investigated microplastic pollution in sediments of the Torghabeh River in northeast Iran. The study found an average concentration of 8 particles per 100 grams of dry sediment, with polystyrene being the most abundant polymer, and areas with greater human activity showing higher levels of microplastic contamination.
Assessment of Groundwater Contamination by Microplastic Particles: A Case Study in Selected Areas of Mosul District, Iraq
A study of twelve groundwater wells across urban and rural areas of Mosul, Iraq, found microplastic contamination in all samples, ranging from 18 to 103 particles per liter. Most particles were small (under 1 mm), with fibers and fragments both present, and polymer types including polyethylene and polypropylene identified by infrared spectroscopy. Groundwater is a primary drinking water source for millions of people in arid regions, and finding widespread microplastic contamination at these levels underscores the need for water treatment systems capable of removing plastic particles before consumption.
New Additions to the Sediments of the Tigris River from Al-Dora Bridge to Al-Mada'in for the Period 2015-2024
This study examined sediment dynamics and microplastic additions in a stretch of Iraq's Tigris River, documenting new microplastic inputs from urban and agricultural discharge and characterizing the sediment composition changes resulting from ongoing urban development and climate pressures.
