Emerging Microplastic Threats to Global Water Sustainability: Reviewing Polymer, Morphology, and Toxicity Patterns Across Water Matrices
AI summary Read the abstract
A systematic analysis of 143 global studies (2011–2025) found that polyethylene, polypropylene, and PET fibers and fragments dominate microplastic contamination across treated, bottled, groundwater, and surface water, with PVC and polystyrene posing the highest toxicological risk due to additive leaching. The review projects escalating water microplastic pollution driven by growing plastic production and climate change, with the greatest impacts falling on developing nations.
Global water sustainability is increasingly threatened by microplastic (MP) contamination, yet a unified understanding of the specific polymer and morphological profiles across different water systems remains fragmented. This review provides the first comprehensive synthesis focusing specifically on polymer and morphological characteristics, rather than abundance alone, across four critical water matrices: treated, bottled, groundwater, and surface water. A total of 143 global studies were systematically analyzed (2011–2025) to: (a) identify dominant MP polymers and morphologies; (b) map their distribution across water types; (c) elucidate potential sources; (d) assess regional variations; (e) evaluate polymer-specific toxicity; (f) analyze exposure pathways; and (g) project future trends. Findings reveal that polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) as fibers and fragments are ubiquitous, with surface water being the most studied matrix. Polyvinyl chloride (PVC) and polystyrene (PS) raise the highest toxicological concerns due to additive leaching. Tropical regions show a higher propensity for fibrous contamination. Projections indicate escalating pollution, driven by increasing plastic production and climate change, with disproportionate impacts on developing nations. This synthesis emphasizes an urgent need for polymer-targeted mitigation strategies, advanced water treatment, and harmonized global monitoring to safeguard water resources and achieve Sustainable Development Goal (SDG) 6.

Microplastics as Water Pollutants and Sustainable Management Strategies
AI summary Read the abstract
This review traced the exponential rise in plastic production since 1950 to over 381 million tons by 2015 and evaluated sustainable management strategies for microplastic water pollution, including source reduction, advanced filtration, and policy frameworks. Addressing microplastic pollution at scale requires systemic approaches that combine upstream production limits with downstream removal technologies, since the volume of particles already in circulation will persist in water systems for generations.

The threats of micro- and nanoplastics to aquatic ecosystems and water health
AI summary Read the abstract
This review details how micro- and nanoplastics in global water sources indirectly threaten water quality by disrupting carbon, nitrogen, phosphorus, and sulfur biogeochemical cycles, transporting pathogens, and amplifying the persistence and bioavailability of co-occurring contaminants. The analysis calls for advanced water treatment technologies, early warning systems, and integrated regulatory frameworks to protect water security from the cascading effects of microplastic pollution.
