The abundance of microplastic pollution along the Jajroud river of Tehran: Estimating the water quality index and the ecological risk
Researchers measured microplastic abundance and water quality in the Jajroud River, a major drinking water source for Tehran, Iran, across multiple seasons.

Surface water samples were collected monthly from four sites along the Shatt al-Arab River in southern Iraq from October 2023 to March 2024 and analyzed for microplastic contamination using sieves and microscopy. Microplastics were confirmed present across all sites, with fragment morphology and multiple polymer types detected.
Microplastic Removal in Water Treatment System: A Study of Baghdad’s Wastewater and Drinking Water Treatment Plants
Researchers analyzed microplastic levels at inlets and outlets of two drinking water plants and two wastewater plants in Baghdad, Iraq, characterizing particles by color, shape, size, and composition to assess treatment efficiency and identify residual contamination in treated water.
Evaluation of microplastic pollution in a lotic ecosystem and its ecological risk
Researchers measured microplastic contamination in water and sediment of the Tigris River in Iraq across dry and wet seasons, finding high abundances of 3429.2 MPs/m3 in water and 121.2 MPs/kg in sediment. Fiber and fragment morphologies dominated, composed primarily of polyethylene and polypropylene, with ecological risk assessment indicating significant pollution hazard.
First evidence of microplastics in a freshwater river and their relationship to water quality
Researchers measured microplastic concentrations in a freshwater river used for recreational purposes and found a significant relationship between microplastic abundance and water physicochemical quality parameters, along with the presence of three organic compounds, providing evidence that microplastic pollution and water quality are closely linked.
Microplastics Evaluation in Tap Water in Left Side Districts of Mosul City, Iraq
Researchers examined microplastic abundance, polymer type, and morphology in tap water from 16 districts in the left side of Mosul city, Iraq, sourced from two different drinking water treatment plants. Using FTIR spectroscopy and stereomicroscopy, the study characterized microplastic contamination levels and features to assess drinking water quality and treatment plant effectiveness in removing plastic particles.
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.
Integrated water quality dynamics in Wadi Hanifah: Physical, chemical, and biological perspectives
This study assessed water quality in Wadi Hanifah, Saudi Arabia, finding significant contamination from industrial discharge and sewage runoff, including high ammonia levels, heavy metals, and fecal bacteria. While not focused on microplastics specifically, the research highlights how waterways accumulate multiple pollutants that can threaten human health. Since microplastics often carry these same contaminants, understanding overall water pollution provides context for the combined risks people face from contaminated water sources.
Exploring correlations between microplastics, microorganisms, and water quality in an urban drinking water source
This study explored the relationships between microplastics, microorganisms, and water quality in China's Xiangjiang River, a source of urban drinking water. Researchers found that microplastic levels were higher near urban areas and wastewater plant outlets, and that the smallest particles showed the strongest correlations with microbial community changes, suggesting complex interactions between plastic pollution and river ecosystems.
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.
Occurrence of Microplastics in Kemena River and Niah River of Sarawak, Malaysia
Researchers investigated microplastic occurrence in water and riverbed sediments of the Kemena and Niah Rivers in Sarawak, Malaysia, finding that urbanization along these rivers correlates with higher microplastic concentrations in freshwater environments.
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.
Risk Assessment of Climate Change Impacts on Urban Discharge Fraction and Eutrophication in Large European River Networks
Researchers assessed how climate change could worsen water quality in European rivers by increasing nutrient pollution from urban areas. While not focused on microplastics, this study highlights the broader environmental pressures on freshwater systems that also carry microplastic contamination.
Characteristics, Contamination Levels, and Ecosystem Risk Assessment of Microplastics in Surface Water of a Highly Urbanized River from a Developing Country
Researchers characterized microplastic contamination in an urban river near a megacity in a developing country, finding concentrations of 350 to 660 particles per cubic meter of water. Polyethylene and polypropylene from household and municipal waste were the most common types, and a risk assessment found concerning contamination levels at several sampling sites. The study highlights how rivers in developing nations can serve as major pathways for microplastics to reach the ocean and enter the food chain.
Assessment of Micro-Plastic Contamination in Urban River Systems: A Case Study Using UK Catchment Data
This systematic review examines microplastic contamination in urban rivers across the UK, finding that wastewater treatment plants, stormwater runoff, and industrial discharge are the main sources. The research matters for human health because urban rivers supply drinking water and recreational areas, and microplastic pollution in these waterways increases the risk of human exposure.
