From Sources to Solutions: A Holistic Review of Microplastic Pollution and Its Environmental Implications
AI summary Read the abstract
This review summarizes existing research on tiny plastic particles called microplastics, covering where they come from, how they spread through water, soil and air, and their effects on fish and ecosystems. It also reviews cleanup methods and notes that while human exposure is well documented, evidence linking it to health problems remains limited.
Microplastics (MPs) have become global, persistent pollutants found across multiple environments, posing significant ecological and public health challenges. This review provides an in-depth analysis of microplastic contamination, detailing its origins, categories, and physicochemical properties that influence the fate, mobility, and toxic effects of MPs in the environment. It also emphasizes modern analytical and detection techniques that enable the precise characterization and measurement of MPs in various ecosystems. The review examines MPs in aquatic, terrestrial, and atmospheric environments, including sea spray aerosols, ambient air, and agricultural lands, and highlights their widespread distribution globally. The ecological hazards posed to aquatic species, especially fish, and their associated human health implications are critically assessed. Additionally, diverse mitigation and wastewater treatment techniques, including nanotechnology-based solutions, are reviewed for their efficiency. Broader aspects such as socioeconomic impacts, regulatory initiatives, and policy responses to contamination are also addressed. The review concludes by outlining the emerging issues and future directions toward sustainable control and reduction in this escalating environmental menace. The reviewed evidence shows that smaller and irregular particles generally exhibit greater mobility and biological accessibility; reported environmental concentrations depend strongly on sampling and identification methods; and no single treatment technology provides universal removal across MP/NP sizes and water matrices. Physical and membrane processes are comparatively mature for particle capture, whereas catalytic, biological, and nanomaterial-assisted approaches remain promising but require stronger evidence on energy demand, secondary residues, durability, and full-scale performance. Human exposure is well documented, but evidence linking exposure to adverse human-health outcomes remains limited.

Tiny plastic particles called microplastics have worked their way into soil, water, air, plants, animals, and eventually our bodies, and scientists still aren't sure exactly what long-term harm this causes to our health. This review pulls together existing research on how microplastics move through ecosystems and accumulate in living things, while also highlighting promising cleanup methods—but it stresses that more research is urgently needed to fully understand the risks and find better solutions.
Microplastics in the environment: sources, impacts, and strategies for mitigation
AI summary Read the abstract
Tiny plastic bits called microplastics, created when everyday plastic items break down, have been found in surprising places, including our blood, fish, soil, and water, and scientists are still working to understand exactly how harmful they are. This review pulls together what researchers currently know about where these particles come from, how they spread, and what methods might remove them, while pointing out that we still lack solid answers on their long-term health effects and the best ways to clean them up. The takeaway: microplastic pollution is a growing concern worth watching, even though the science on its full impact to our bodies is still catching up.
