Plastic pollution: European farmland could be largest global reservoir of microplastics
AI summary Read the abstract
European farmland may represent the world's largest reservoir of environmental microplastics, with an estimated 42,000 tonnes of microplastics deposited annually via sewage sludge used as agricultural fertilizer, ultimately washing back into waterways. This finding implicates wastewater treatment practices as a major driver of terrestrial microplastic accumulation and downstream contamination of food crops and drinking water sources.
Up to 42,000 tonnes a year of microplastics are removed from sewage, spread on fields as fertiliser and eventually wash back into watercourses.

How microplastics are making their way into our farmland
AI summary Read the abstract
This commentary argues that wastewater treatment plants are a primary pathway for microplastics entering Canadian farmland through biosolid application, calling for closer monitoring and reduction of microplastics in the wastewater stream. Agricultural soil microplastic accumulation is a growing concern because it contaminates crops, disrupts soil ecosystems, and creates a diffuse pathway for plastic particles to enter the human food supply.
Microplastics in Crops
AI summary Read the abstract
Researchers reviewed how microplastics accumulate in agricultural soils and are taken up by crop plants, raising food safety concerns as these particles and their associated chemical contaminants may enter the human food supply through plant consumption.
Hazards of Microplastic Pollution in Agriculture
AI summary Read the abstract
This review examined the sources and hazards of microplastic pollution in agricultural settings, including plastic mulch degradation, sewage sludge application, and plastic packaging, and their effects on soil health and crop systems. Agricultural microplastic exposure is especially significant for human health because it creates a direct farm-to-table contamination pathway, with particles and leached chemicals potentially present in vegetables, grains, and livestock products.
Microplastics in Agricultural Soils
AI summary Read the abstract
Researchers reviewed what is known about microplastic contamination in agricultural soils, noting that despite hundreds of millions of tonnes of plastic entering the environment annually, very little is understood about how microplastics persist, migrate, and affect soil ecosystems. This knowledge gap is concerning given that contaminated soil directly affects food crops consumed by humans.
Unravelling the emerging threats of microplastics to agroecosystems
AI summary Read the abstract
This review synthesizes evidence that microplastics accumulate in agricultural soils from multiple pathways, disrupting soil physical and chemical properties, shifting rhizosphere microbial communities, and potentially entering plants through water and nutrient uptake channels. Because most microplastic research has focused on aquatic systems, the effects of soil MP contamination on crop yield, food quality, and long-term agricultural sustainability remain critically underexplored.
