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.

Laboratory and field experiments in Bihar, India examined how plastic microbeads, pesticides, mercury, crude oil, and pharmaceuticals affect fish health, finding organ damage, reproductive failure, and elevated mortality across multiple pollutant types.
Impact of Pollution and Toxic Stress on Fish Health: Mechanisms, Consequences, and Mitigation Strategies
This review examined the many ways pollution and toxic substances harm fish health, including through disrupted metabolism, hormonal imbalances, weakened immune systems, and reproductive problems. The study highlights that pollutants enter fish through water, food, and sediment, and discusses mitigation strategies for protecting fish populations and the broader aquatic ecosystems they support.

Not relevant to microplastics — this study assesses reproductive health in three freshwater fish species from a Turkish river contaminated by heavy metals from agricultural and industrial wastewater, with no mention of microplastics.
Occurrence of Micro-Plastics in Tigris River Water in Middle of Iraq
This study detected microplastic particles in surface water samples from the Tigris River in Baghdad, Iraq, finding between 27 and 74 particles per sample with polypropylene and polyethylene being the most common types. The results establish a baseline for microplastic contamination in a major Middle Eastern river system that supplies water to millions of people.
Microplastics and heavy metals in freshwater fish: A comprehensive study of contamination and health risks
Researchers simultaneously assessed microplastic and heavy metal contamination in two fish species from Iran's Kashkan River, finding microplastics in 79% of the 48 specimens examined. The study also found heavy metal levels that exceeded safe limits, raising human health concerns for communities consuming these fish.
Effects of microplastics in freshwater fishes health and the implications for human health
This review examines how microplastics affect the health of freshwater fish, which are a major protein source for billions of people. Fish ingest microplastics that accumulate in their guts, gills, and tissues, leading to inflammation, oxidative stress, and disrupted growth. Since microplastics in fish tissue can transfer to humans through the food chain, this is relevant to both ecosystem and human health.
Water Quality and Fish Health: Interaction with Toxic Substances
This review examines how various toxic substances in water, including microplastics, affect fish health through physiological, behavioral, and biochemical pathways. Researchers summarized evidence that pollutants can accumulate in fish tissues and impair their immune systems, reproduction, and organ function. The study emphasizes that declining water quality from emerging contaminants poses growing risks to aquatic ecosystems and the species that depend on them.
Microplastic Pollution – An Emerging Concern for Freshwaters: Effects and Overcome to Microplastic Pollution
This review addresses microplastic impacts on freshwater ecosystems, covering morphological and physiological toxicity to fish, food chain implications, and potential strategies to mitigate plastic pollution in urban water bodies.
Assessing the Effects of Microplastics on Freshwater Fish
This review examines the growing body of research on how microplastics affect freshwater fish, documenting evidence of ingestion, tissue damage, immune system impairment, and gastrointestinal obstruction across multiple species. Researchers highlight that microplastics from personal care products and degraded plastic goods are accumulating in freshwater ecosystems at concerning rates. The study warns that combined with existing threats like overfishing and habitat loss, microplastic pollution could accelerate population declines in vulnerable fish species.
Microplastics in Aquatic Environments and Their Toxicological Implications for Fish
This review summarizes research on microplastic occurrence in freshwater and marine environments and the toxicological risks they pose to fish, examining both direct physical effects and the role of plastics as vectors for chemical pollutants. The authors highlight that freshwater fish are particularly vulnerable given the high loads of microplastics in rivers receiving wastewater.
Effect of Aquatic Pollution on Fish in Libya: A Review
This review of aquatic pollution in Libyan waters identified heavy metals, microplastics, PAHs, and artificial detergents as major contaminants from industrial, petrochemical, and agricultural sources, documenting their harmful biological effects on fish species along Libya's coastline.
