Microplastics (MPs) are emerging contaminants characterized by persistence, cross-media transport, and complex pollutant interactions, posing serious ecotoxicological risks to ecosystems human health. Effective MPs management requires multi-faced, long-term, strategies involving targeted sampling, quantitative detection, comprehensive risk assessments, all of which entail significant resource investment. Despite advancements in remediation technologies, a holistic governance framework integrating these innovations remains underdeveloped. This review synthesizes current knowledge on MPs, elaborating their diverse morphologies, degradation pathways, role as vectors for toxic substances. State-of-the-art extraction techniques evaluated this article, including micropore adsorption using nanocomposites, alongside the incorporation advanced analytical tools such spectroscopic methods, electron microscopy, bioinformatics augment environmental forensics. also underscores necessity formulating robust global policies regulate pollution discusses potential biodegradation thermal sustainable solutions removal. By promoting an interdisciplinary approach, advocates coordinated response, science, policy frameworks, waste mitigate escalating impact well-being.

Microplastic (MP) pollution is a prevalent and global threat to fish. MP contamination was investigated in Harpadon nehereus collected from the principal fishing harbors of India’s northwest coast. A total 213 specimens were major Gujarat state (Jakhau, Okha, Jaffrabad) Maharashtra (Mumbai). In laboratory, morphometric parameters specimens, such as length body weight, measured. The analyzed for isolation using previously documented protocol. MPs quantified under stereomicroscope, physical recorded. All examined found be contaminated with MPs, an abundance 6.98 ± 6.73 MPs/g. maximum recorded at study site Jaffrabad, followed by Jakhau, Mumbai, Okha. Morphometric analysis revealed threads most dominant shape. Black blue 1–2 mm size predominant types. chemical composition extracted polyethylene (PE), polystyrene (PS), polyurethane (PU) polymer compositions. Conclusively, findings highlighted greater menace seafood safety due trophic transfer, which causes hazardous effect on human health.

Current scenario of emerging pollutants in farmlands and water reservoirs: Prospects and challenges

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 291, P. 117829 - 117829

Published: Feb. 1, 2025

Globally, roughly more than 400 million metric tons of plastics are produced annually. Similarly, the pharmaceuticals business is rising exponentially yearly, 5.8 %. It expected to increase from USD 714 billion 1454 by 2029. Beyond their intended uses, these substances released into environment as contaminants due improper usage and management practices. Therefore, microplastics (MPs) classified emerging pollutants (EPs), existence in agricultural ecosystems adversely affects soil environmental health, ultimately impacting both ecological human well-being. Pharmaceuticals MP-loaded organic amendments (especially manure) a primary cause pollutants. The increasing application treated wastewater or biosolids irrigation water conditioners, mainly when derived untreated sewage sludge, can introduce MPs farmlands, merging within medium. co-occurrence leads prolonged presence gradual bioaccumulation organisms over time, contributing persistent contamination long-lasting effects on ecosystems. Moreover, EPs have potential alter composition biogeochemistry disrupt overall health productivity. Numerous methods been developed address this issue, including electrochemical degradation, advanced oxidation processes, photocatalytic biosurfactants, micro- nano-bubble systems, ultrasonic cavitation, nanotechnology, constructed wetlands, many hybrid approaches. This review explores extent EPs, interactions, strategies EPs-contaminated environments.
