Interactıon of Micro-Nanoplastics and Heavy Metals in Soil Systems: Mechanism and Implication
AI summary Read the abstract
Researchers examined how micro- and nanoplastics interact with heavy metals in soil, finding that plastics can alter metal mobility, bioavailability, and toxicity through adsorption and chemical reactions, raising concern that plastic pollution may worsen the risk posed by existing heavy metal contamination in agricultural and urban soils.
Various organic and inorganic contaminants have been detected in soil systems among which heavy metals are one of the most studied ones. Additionally, micro-nanoplastics have been introduced as recent contaminant into soil systems by composting, mulching, biosolid...

Interactions of Microplastics with Co-Occurring Pollutants in Soil Environment
AI summary Read the abstract
This review examines how microplastics in soils interact with co-occurring pollutants including heavy metals, organic contaminants, and biological pollutants, analyzing the mechanisms and environmental factors governing these complex interactions. Because microplastics act as vectors that adsorb and transport other contaminants through soil, understanding these interactions is critical for assessing the combined toxicity and ecological risk of plastic pollution in terrestrial food-producing systems.
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.
Long-Term Fate of Micro/Nanoplastics in Soil Systems and Their Impacts
AI summary Read the abstract
Researchers examined the long-term fate of micro- and nanoplastics in soil, finding that these persistent particles accumulate over time and can disrupt soil ecosystems, potentially affecting plant growth, soil organisms, and the broader food chain through sustained environmental exposure.
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."
Micro- and Nanoplastics as Carriers for Other Soil Pollutants
AI summary Read the abstract
Researchers reviewed how microplastics in soil serve as vectors for co-transport of other pollutants — including heavy metals, pesticides, and antibiotics — with annual terrestrial plastic releases estimated at 4–23 times those entering the marine environment. This carrier effect means soil microplastic contamination amplifies the bioavailability and toxicity of co-occurring chemical pollutants, compounding risks to soil organisms, crops, and ultimately human consumers.
