ClearInvestigating the amount of macro, meso, and microplastics in the surface soil around the landfill of Tabriz and the effect of the prevailing wind on their distribution
Researchers sampled soil around an improperly managed landfill in Tabriz, Iran, finding it heavily contaminated with microplastics — averaging 470 particles per kilogram of dry soil — along with larger meso- and macroplastic debris. Surprisingly, the prevailing wind had little influence on how the microplastics spread around the site; the pollution was widespread in all directions. Open and poorly managed landfills are a significant and underappreciated source of microplastic contamination in surrounding soils and communities.

Researchers measured microplastic contamination in soil at a landfill near residential areas in Indonesia and found extremely high levels of over 60,000 particles per kilogram. The most common types were fragments of polyethylene, PVC, polystyrene, and polypropylene. The study raises public health concerns because landfills near populated areas can release microplastics into surrounding soil and water, creating exposure pathways for nearby communities.
Abundance and characteristics of microplastics in soil and leachate at different zones of unsanitary landfill
Researchers investigated microplastic contamination in soil and leachate across young, middle-aged, and old zones of an unsanitary landfill. They found that fiber-shaped microplastics were most common, with PET, polypropylene, and polystyrene as the dominant polymers, and that leachate from middle-aged zones had significantly lower microplastic abundance than young or old zones. The study shows that landfill age and environmental degradation influence how microplastics are distributed between soil and leachate.
