Microplastics in landfill soils of Lichinga, Mozambique: occurrence, polymer diversity, and depth-related distribution

Summary

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.
