Microplastic pollution in long-term urban compost amended soils
AI summary Read the abstract
This study examined microplastic pollution in soils that had received long-term amendments of urban compost, finding significant plastic contamination from compost application. The results highlight that composting can be a pathway for microplastics to enter agricultural soils.

Plastic contamination of soil: is compost the source?
AI summary Read the abstract
Researchers assessed compost as a source of plastic contamination in agricultural soils, finding detectable levels of microplastics in commercial composts that are subsequently applied to farmland. This study identifies composting of plastic-contaminated organic waste as an underappreciated pathway for microplastic introduction into agroecosystems.
Coarse microplastic accumulation patterns in agricultural soils during two decades of different urban composts application
AI summary Read the abstract
Researchers analyzed 21 years of soil samples from fields treated with three different types of urban waste compost to track how microplastics accumulate over time. They found that all compost types introduced microplastics into the soil, with distinct patterns depending on the compost source, and that certain plastic types persisted and built up over decades. The study suggests that long-term compost application is a significant pathway for microplastic accumulation in agricultural soils.
Microplastic contamination of soil: Are input pathways by compost overridden by littering?
AI summary Read the abstract
Researchers investigated whether compost application is a major pathway for microplastic contamination of agricultural soil using a long-term fertilizer trial. The study found that while compost does contribute microplastics, the levels detected were relatively low compared to microplastics from general littering, suggesting that environmental littering may be a more significant source of soil microplastic contamination than composting.
A long-term field experiment reveals the accumulation of high amounts of microplastics in soils amended with composted waste residues.
AI summary Read the abstract
A long-term field experiment found that soils amended with composted waste residues accumulated high amounts of microplastics over time. The composted materials introduced plastic particles into agricultural soils even after processing, raising concerns about contaminating farmland through organic waste recycling. This study highlights composting as an overlooked pathway for microplastic introduction to soil.
Biowaste Compost Amendment is a Source of Microplastic Pollution in Agricultural Soils
AI summary Read the abstract
Researchers found microplastics in Indian agricultural soils amended with biowaste compost, with concentrations increasing in proportion to years of compost application. Polypropylene was the dominant polymer type, showing that compost amendments can introduce microplastics into farmland soils.
