Environmental Science and Ecotechnology, Journal Year: 2024, Volume and Issue: 21, P. 100427 - 100427

Published: April 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.

Published: Jan. 1, 2024

The escalating production and ubiquitous presence of plastics their degradation products, such as microplastics nanoplastics, pose a significant environmental threat. Microplastics enter the soil through various pathways, including agricultural practices, plastic degradation, wastewater disposal. Herein, we discussed harmful effects on physicochemical properties soil, plant growth, terrestrial fauna, microbial activity, potentially affecting stability nutrient cycle ecosystem. This review delves into recent advances in potential microplastic bioremediation approaches, phytoremediation strategies utilized by plants associated microbes to accumulate, immobilize, even degrade microplastics. Rhizosphere microorganisms play crucial role microplastics, utilizing them carbon source. Soil animals like earthworms, snails, mealworms can also contribute significantly ingesting degrading gut microbiota. Various microorganisms, bacteria fungi, different with help enzymes laccase, esterase, peroxidase, oxidoreductase, hydrolases depolymerise larger polymer chains smaller units that ultimately mineralize CO2, H2O, CH4. Genetic engineering synthetic biology are used create strains enhanced mineralization capabilities. It holds promise for efficient but requires further research real-world application scalable implementation. Overall, this comprehensively highlights approaches future recommendations tackling pollution. Further development enhancing biodegradation efficiency scaling up strategy protection.

Progress and future directions bridging microplastics transport from pore to continuum scale: A comprehensive review for experimental and modeling approaches

TrAC Trends in Analytical Chemistry, Journal Year: 2024, Volume and Issue: 179, P. 117851 - 117851

Published: July 4, 2024

The anomalous (i.e., non-Fickian) transport characteristics (e.g., early arrival/long tailing and other non-Gaussian plume properties) make it challenging to apply classical theories the retention of microplastics in soil due their heterogeneity. This overview attempts 1) delineate previous studies on colloids MPs, which used recently developed analytical devices microfluidics micro-CT) process-based lattice Boltzmann method (LBM) pore network modeling (PNM)) or data-driven models machine learning (ML) techniques) 2) provide future directions for bridging pore- continuum-scale properties. Although LBM PNM offer significant advantages depicting particle at scale, employment larger scales is hindered by computational demands. Nonetheless, applying these methods generate datasets ML techniques anticipated a robust tool an accurate rapid model.
