Microplastics in urban areas: analysis of microplastics spreading potential from decommissioned landfill in Lichinga city, Mozambique, Southern Africa
AI summary Read the abstract
Researchers used stereomicroscopy to analyze microplastic distribution in soil samples collected near a decommissioned landfill in Lichinga, Mozambique, assessing the spatial spread of plastic contamination from an unmanaged waste site into surrounding urban soils.
Microplastics in landfill soils of Lichinga, Mozambique: occurrence, polymer diversity, and depth-related distribution
AI summary Read the abstract
Researchers found tiny plastic particles (microplastics) buried in landfill soil in Lichinga, Mozambique, at various depths and in many different plastic types. This matters because these plastics can break down further, potentially seeping into groundwater or soil where crops grow, creating a possible pathway for plastic particles to end up in our food and water supply. While this study focused on soil rather than direct health effects, it highlights how landfills may be an overlooked source of environmental plastic pollution that eventually affects human exposure.
Microplastics and Their Distribution in Soil at Municipal Solid Waste Landfills: A Review
AI summary Read the abstract
This review investigated microplastic contamination across soil layers at urban municipal solid waste landfill sites, finding that landfill age and waste composition influence MP type and distribution. It identified landfill soils as understudied long-term MP reservoirs with potential for leaching into surrounding environments.
Occurrence of soil microplastics in a decommissioned landfill area in Mozambique currently occupied by a residential settlement

Note: The abstract provided only describes photos and spectral images, without giving actual findings, so a full summary isn't possible from this text. Here's what can be said: Researchers studied soil from an old landfill site in Mozambique where people now live, looking for tiny plastic particles called microplastics. This matters because when landfills are converted into housing without proper cleanup, residents could unknowingly be exposed to plastic contamination in the soil around their homes — a growing concern since microplastics have been linked to potential health risks when they enter the body through skin contact, dust, or homegrown food.
Examining Soil Microplastics: Prevalence and Consequences Across Varied Land Use Contexts
AI summary Read the abstract
Scientists examined microplastic contamination in soil samples from different land use areas in Makassar City, Indonesia. They found microplastics present across all sites, with the types and concentrations varying based on how the land was used, whether for agriculture, residential, or commercial purposes. The study suggests that human activity patterns strongly influence the amount and kind of microplastic pollution found in urban and agricultural soils.
