Microplastics in Terrestrial Ecosystem: Degradation Strategies for Its Mitigation
AI summary Read the abstract
Researchers reviewing microplastic degradation strategies in terrestrial ecosystems found that pandemic-related increases in single-use plastic use have worsened soil contamination, and evaluated biodegradation, photodegradation, and other mitigation approaches for reducing microplastic persistence in soil environments.
Microplastics (MPs) are emerging pollutants that pose a serious threat to biodiversity, which has become a global environmental concern. In addition, coronavirus disease (Covid-19) has increased the demand for single-use plastics, which has exacerbated the already...

Microplastics in Terrestrial Ecosystems
AI summary Read the abstract
This review assessed microplastic accumulation in terrestrial ecosystems — including agricultural soils, forests, and urban environments — documenting effects on soil structure, earthworm health, plant growth, and microbial diversity driven by decades of dramatic plastic production growth. Because terrestrial environments receive far more microplastic deposition than oceans yet are less studied, the soil contamination documented here directly threatens food production and represents a major underappreciated source of human dietary microplastic exposure through crops and soil-grown produce.
The Migration, Biotoxicity and Biodegradation Methods of Microplastics in Terrestrial Ecosystems: A Comprehensive Review
AI summary Read the abstract
Researchers reviewed how microplastics migrate globally via atmospheric and riverine transport, accumulate in remote ecosystems, and cause physical damage, oxidative stress, and endocrine disruption in organisms that ingest them. This comprehensive toxicity profile—including size-dependent effects and amplified harm from adsorbed contaminants—directly informs human health risk assessments given the widespread presence of microplastics in food and water.
Micro and nanoplastics in terrestrial ecosystems: pathways, health implications, and mitigation strategies
AI summary Read the abstract
Tiny plastic fragments from things like plastic mulch, tires, and compost are building up in farm soils, breaking down further, and getting absorbed by plant roots, meaning they could be entering the food we eat. This review pulls together existing research showing these particles can also harm soil health and plant growth, and while early studies suggest they may cause inflammation and cellular stress in living things, scientists still don't have solid data on how risky this is for human health. The takeaway: it's a real and growing concern worth watching, but more research is needed before we know exactly how much it affects us.
Microplastics Effects in the Terrestrial Environment
AI summary Read the abstract
Microplastics released into soil systems interact with complex terrestrial matrices in ways that threaten soil health, plant uptake, and the organisms that depend on healthy soils, including humans who consume agricultural produce. Their resilience and long environmental persistence make soil microplastic contamination particularly difficult to remediate once established.
Microplastics Effects in the Terrestrial Environment
AI summary Read the abstract
Microplastics released into soil systems interact with soil chemistry, microbial communities, and plant uptake pathways in ways that threaten terrestrial ecosystem health over time. Because soils are foundational to food production and filter water that reaches humans, microplastic accumulation in terrestrial environments carries direct implications for agricultural safety and human dietary exposure.
