Microplastic pollution in the marine environment: A review

Journal of Hazardous Materials Advances, Год журнала: 2023, Номер 10, С. 100327 - 100327

Опубликована: Май 1, 2023

The quantity of plastic materials produced worldwide is progressively increasing. For instance, annual global production has increased from 1.5 to 390.7 million metric tons 1950 2021. Meanwhile, inefficient management strategies have resulted in huge waste disposal (i.e., the form macro-, micro-, and nanoplastics) environment a hostile manner. In particular, such uncontrollable discarding paves entrance pollution into as microplastics (μPs) after degradation macroplastics. this respect, marine environments are most typical regions prone μP pollution. These ubiquitous emerging pollutants can also adsorb other pollutants, organic materials, toxic heavy metal ions, pathogens, transfer them living organisms. main theme present study compile information on how affects ecosystem, with particular emphasis following key factors: (i) types sources μPs, particularly those entering sinks; (ii) mechanisms leading μPs' degradation; (iii) poisonous effects μPs biota humans; (iv) fate environment, including their transportation routes deposition modes, (v) recent developments characterization, separation, removal environment. presented here would be practical for developing effective risk plans.

A critical review of microplastics in aquatic ecosystems: Degradation mechanisms and removing strategies

Environmental Science and Ecotechnology, Год журнала: 2024, Номер 21, С. 100427 - 100427

Опубликована: Апрель 25, 2024

Plastic waste discarded into aquatic environments gradually degrades smaller fragments, known as microplastics (MPs), which range in size from 0.05 to 5 mm. The ubiquity of MPs poses a significant threat ecosystems and, by extension, human health, these particles are ingested various marine organisms including zooplankton, crustaceans, and fish, eventually entering the food chain. This contamination threatens entire ecological balance, encompassing safety health systems. Consequently, developing effective MP removal technologies has emerged critical area research. Here, we summarize mechanisms recently reported strategies for removing ecosystems. Strategies combining physical chemical pretreatments with microbial degradation have shown promise decomposing MPs. Microorganisms such bacteria, fungi, algae, specific enzymes being leveraged remediation efforts. Recent advancements focused on innovative methods membrane bioreactors, synthetic biology, organosilane-based techniques, biofilm-mediated remediation, nanomaterial-enabled strategies, nano-enabled demonstrating substantial potential enhance efficiency. review aims stimulate further innovation methods, promoting environmental social well-being.

Phytoremediation of microplastics by water hyacinth

Environmental Science and Ecotechnology, Год журнала: 2025, Номер 24, С. 100540 - 100540

Опубликована: Фев. 11, 2025

Microplastics have emerged as pervasive environmental pollutants, posing significant risks to both terrestrial and aquatic ecosystems worldwide. Current remediation strategies-including physical, chemical, microbial methods-are inadequate for large-scale, in situ removal of microplastics, highlighting the urgent need alternative solutions. Phytoremediation, an eco-friendly cost-effective technology, holds promise addressing these challenges, though its application microplastic pollution remains underexplored. Here we show capacity Eichhornia crassipes (water hyacinth), a fast-growing, floating plant, remove microplastics from contaminated water. Our results that within 48 h, water hyacinth achieved efficiencies 55.3 %, 69.1 68.8 % 0.5, 1, 2 μm polystyrene particles, respectively, with root adsorption identified primary mechanism. Fluorescence microscopy revealed extremely large abundant caps, featuring total surface area exceeding 150,000 mm2 per serve principal sites entrapment microplastics. Furthermore, unique "vascular ring" structure stem prevents translocation aerial tissues, safeguarding leaves potential downstream applications. This study offers first microstructural insight into mechanisms underpinning hyacinth's exceptional resilience, providing promising framework developing phytoremediation strategies mitigate ecosystems.
