Microplastics in Terrestrial Ecosystems

2024 3 citations

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.

Globally, the generation of plastics has increased dramatically since 1950 due to population growth, urbanization, and industrialization, making our environment a menace of plastic pollution. Despite the exponential growth of microplastics (MPs), the adoption of...

Microplastics in the Terrestrial Environment

AI summary Read the abstract

This book synthesizes current research and knowledge gaps regarding microplastic impacts across terrestrial ecosystems, including soils, plants, and land-dwelling organisms. Compiling terrestrial microplastic research is essential as land environments receive far more microplastic input than oceans yet remain comparatively understudied, particularly regarding food crop contamination and soil ecosystem disruption.

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.

Micro- and Nanoplastic Pollution in Terrestrial Ecosystems

AI summary Read the abstract

Micro- and nanoplastics have spread ubiquitously across terrestrial ecosystems, persisting in soil and affecting plant health, soil organisms, and nutrient cycling. Their slow degradation and widespread distribution make them a long-term threat to ecosystem function and agricultural productivity.

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.
