Steps to reproduce

This study innovatively constructed a migration model of soil nanoplastics under the background of snowmelt infiltration, predicted the pollution risk of soil nanoplastics under future changing climate scenarios, and further analyzed the regulatory mechanism of the soil environment on the migration and diffusion of nanoplastics.
