Effect of microplastics in water and aquatic systems
Summary
This review examines the sources, distribution, and effects of microplastics in water and aquatic systems globally. Researchers found that microplastics are ingested by a wide range of aquatic organisms, leading to accumulation of toxic substances and disruption of physiological functions. The study highlights the urgent need for better waste management policies and further research into the long-term ecological consequences of microplastic pollution in freshwater and marine environments.
Surging dismissal of plastics into water resources results in the splintered debris generating microscopic particles called microplastics. The reduced size of microplastic makes it easier for intake by aquatic organisms resulting in amassing of noxious wastes, thereby disturbing their physiological functions. Microplastics are abundantly available and exhibit high propensity for interrelating with the ecosystem thereby disrupting the biogenic flora and fauna. About 71% of the earth surface is occupied by oceans, which holds 97% of the earth's water. The remaining 3% is present as water in ponds, streams, glaciers, ice caps, and as water vapor in the atmosphere. Microplastics can accumulate harmful pollutants from the surroundings thereby acting as transport vectors; and simultaneously can leach out chemicals (additives). Plastics in marine undergo splintering and shriveling to form micro/nanoparticles owing to the mechanical and photochemical processes accelerated by waves and sunlight, respectively. Microplastics differ in color and density, considering the type of polymers, and are generally classified according to their origins, i.e., primary and secondary. About 54.5% of microplastics floating in the ocean are polyethylene, and 16.5% are polypropylene, and the rest includes polyvinyl chloride, polystyrene, polyester, and polyamides. Polyethylene and polypropylene due to its lower density in comparison with marine water floats and affect the oceanic surfaces while materials having higher density sink affecting seafloor. The effects of plastic debris in the water and aquatic systems from various literature and on how COVID-19 has become a reason for microplastic pollution are reviewed in this paper.

Microplastics in Aquatic Environments
This review examined microplastics as ubiquitous pollutants in aquatic environments, tracing their origins in large-scale plastic production and inadequate waste management systems and synthesizing evidence on their distribution, ecological impacts, and implications for global water quality.
Microplastics in aquatic environments: A review on occurrence, distribution, toxic effects, and implications for human health
This review examines the global occurrence of microplastics in aquatic environments and their potential impacts on both aquatic organisms and human health. Researchers found that microplastics are now present in virtually all freshwater and marine systems, where they cause a range of harmful effects including oxidative stress, inflammation, and reproductive disruption in aquatic species. The study highlights trophic transfer, where microplastics move up the food chain, as a key pathway of human exposure.
A Comprehensive Review on Microplastic Pollution in Aquatic Ecosystems and Their Effects on Aquatic Biota
This comprehensive review examines microplastic pollution across freshwater and marine ecosystems and its effects on aquatic organisms. Researchers found that microplastics are abundant in both environments and that nearly all studies reviewed documented uptake by organisms along with alterations in biochemical parameters. The evidence indicates that microplastic contamination is becoming an increasingly serious environmental and health concern for aquatic life.
Microplastic contaminants in the aqueous environment, fate, toxicity consequences, and remediation strategies
This review covers the sources, fate, and toxic effects of microplastic contaminants in aquatic environments, along with current remediation strategies for removing them. Researchers found that microplastics cause various health problems in aquatic organisms and can enter the human food chain through contaminated seafood and water. The study emphasizes the urgent need for improved waste management and novel cleanup technologies to address microplastic pollution in water systems.
Microplastics in aquatic environments: detection, abundance, characteristics, and toxicological studies
This review summarizes current knowledge about microplastics in water environments, covering how they are detected, how abundant they are, and what toxic effects they have on living organisms. Microplastics are found throughout aquatic systems and can accumulate in organisms while also spreading other pollutants through the environment. The authors emphasize that more attention should be paid to microplastics in freshwater and organisms closely linked to human food sources, as well as toxicity studies in mammals.
