Emerging Techniques for the Mitigation of Micro and Nanoplastics in Soil
AI summary Read the abstract
Researchers reviewed emerging techniques for removing micro- and nanoplastics from soil, where these particles accumulate from agricultural practices, wastewater irrigation, and atmospheric deposition. Soil contamination is a growing concern because microplastics can interact with toxic elements and potentially enter food crops consumed by humans.
For many years, global plastic pollution has been a severe concern, and micro (nano) plastics (MNPs) have attracted the attention of researchers all over the world. Because MNPs can exhibit toxicological and interact with potentially toxic elements (PTEs) in the...

Micro and Nanoplastics in Agricultural Soils: Challenges and Future Directions
AI summary Read the abstract
This review examined the sources, behavior, and ecological effects of micro- and nanoplastics in agricultural soils, highlighting challenges in detection, risk assessment, and regulatory management as plastic use in farming continues to grow. Nanoplastics in particular present heightened concern because their tiny size enables deeper soil penetration, plant uptake into edible tissues, and greater biological reactivity than larger fragments.
Persistence of Micro- and Nanoplastics in Soil
AI summary Read the abstract
This review examined the persistence, fate, and properties of micro- and nanoplastics in soil environments, highlighting significant knowledge gaps in understanding how these particles behave once deposited in terrestrial systems. Because soils represent a major and understudied reservoir for plastic particles, clarifying their persistence and mobility is critical for assessing long-term contamination of crops and groundwater that feed into human exposure.
Soil Pollution by Micro- and Nanoplastics: Sources, Fate, and Impact
AI summary Read the abstract
Researchers examine how micro- and nanoplastics enter soil systems, persist through environmental processes, and threaten soil fertility and ecosystem health, with direct implications for agricultural productivity, food security, and human health.
Soil Pollution by Micro- and Nanoplastics: An Overview
AI summary Read the abstract
"This overview synthesized evidence showing that annual plastic releases to terrestrial environments are 4 to 23 times higher than releases to the ocean, with microplastics entering soil via sewage sludge, compost, plastic mulch, and irrigation. Soil contamination at this scale threatens agricultural food safety and groundwater quality, creating direct pathways for microplastics and associated toxins to enter the human diet through crops and drinking water."
Degradation and remediation of microplastics in soil.
AI summary Read the abstract
Researchers reviewed current approaches to degrading and remediating microplastics in soil, examining both biological and physicochemical strategies for reducing persistent plastic particle accumulation in terrestrial environments.
