Microplastics in Soil: An Emerging Threat
AI summary Read the abstract
Researchers reviewed the emerging problem of microplastic pollution in soil, tracing contamination to agricultural practices, industrial activities, and atmospheric deposition, and examining downstream risks to ecosystem health and human well-being.
Microplastic pollution in soil is an emerging environmental concern with widespread implications for ecosystem health and human well-being. Originating from various sources such as agriculture, industrial activities, and atmospheric fallout, microplastics (MPs)...

Microplastics in Soil: Unveiling the Threat Within the Earth’s Crucial Ecosystem
AI summary Read the abstract
Researchers surveyed the sources, ecological impacts, and remediation strategies for microplastic contamination in soil, revealing that agricultural practices, plastic mulch, sewage sludge application, and atmospheric deposition are primary pathways loading microplastics into terrestrial ecosystems. Soil microplastics threaten plant health, soil microbiome function, and food security while serving as a vector carrying toxic additives and pathogens up the food chain to humans.
Microplastics as Emerging Contaminants: Unraveling Their Impact on Soil Health
AI summary Read the abstract
This review pulls together existing research showing how tiny plastic bits in soil mess with its structure, chemistry, and the microbes that keep it healthy, making it harder for plants to grow and absorb nutrients properly. This matters because these plastics can travel from soil into the crops we eat, and the damage to soil health could shrink crop yields over time, raising concerns about both food safety and food supply.
Impact of Microplastic Pollution on Soil Health
AI summary Read the abstract
Researchers review how microplastics enter agricultural soils from plastic mulch films, sewage sludge, and irrigation water, documenting their effects on soil microbial communities, nutrient cycling, and overall soil health in ways that may threaten long-term agricultural productivity.
Microplastics in soil: a review on research status, sources, methods, and remediation strategies
AI summary Read the abstract
A comprehensive literature review found that soil microplastic research lags far behind aquatic studies despite annual MP discharge into farmland exceeding marine inputs, with synthetic textiles, tire wear, and urban dust as dominant sources entering soil via atmospheric deposition, sewage irrigation, and agricultural film use. The soil MP burden threatens food crop health, risks leaching into groundwater, and poses intergenerational health risks through nutrient disruption and potential plant-to-human transmission pathways.
