Microplastics aren’t just a problem for the ocean – they’re in our soils too
Summary
Microplastic contamination of agricultural soils is now widespread globally, with modeling approaches enabling researchers to estimate pollution levels across regions where direct sampling is limited. Soil microplastics threaten crop productivity and soil ecosystem health, and because they move into groundwater and food crops, they represent a direct human exposure pathway beyond what is found in oceans.
Microplastics are polluting soil worldwide, but it’s often hard to analyse the impact. New research shows how we can assess the scale of the problem using modelling.
