Migration dynamics of PE and PVC microplastics in soil: An experimental column-based investigation on the effects of drip irrigation
Summary
Researchers conducted column experiments to track how polyethylene (PE) and polyvinyl chloride (PVC) microplastics move through soil under drip irrigation conditions, examining how irrigation practices influence the depth and speed at which these plastic particles migrate. The findings have implications for understanding microplastic contamination of agricultural soils and groundwater.

Drip Irrigation Promoted Migration of Microplastic Particles Across Vertical Soil Columns.
Researchers at IIT Roorkee experimentally investigated microplastic particle migration through vertical soil columns under drip irrigation conditions, finding that drip irrigation accelerates downward transport of microplastics across soil horizons compared to surface application scenarios.
Vertical transport of microplastic in agricultural soil in controlled irrigation plot experiments
Researchers conducted field plot experiments in agricultural soil and found that microplastics migrate vertically with irrigation water, with smaller particles (53–63 µm) penetrating up to 6 cm deep and larger particles remaining near the surface, indicating that water infiltration is a key driver of subsurface plastic transport.
Experimental Study on the Migration and Distribution of Microplastics in Desert Farmland Soil Under Drip Irrigation
Researchers studied how microplastics from degraded plastic film migrate through desert farmland soil under drip irrigation conditions in Xinjiang, China. The study found that microplastic movement in soil was influenced by irrigation patterns and soil properties, with particles migrating both vertically and horizontally. Evidence indicates that drip irrigation in plastic-mulched farmland may redistribute microplastic contamination throughout agricultural soils.
Vertical migration of microplastics in porous media: Multiple controlling factors under wet-dry cycling
Researchers studied how microplastics move vertically through sandy soil during cycles of wetting and drying, testing four common plastic types at various particle sizes. They found that smaller, more hydrophobic particles migrated deeper, and that frequent wet-dry cycles and the presence of dissolved organic matter accelerated downward movement. The findings suggest that microplastics in agricultural soils could potentially reach groundwater, posing risks to underground water quality.
Irrigation-facilitated low-density polyethylene microplastic vertical transport along soil profile: An empirical model developed by column experiment
Column experiments examined how irrigation drives vertical transport of low-density polyethylene microplastics through soil profiles, and an empirical model was developed from the results. Microplastics migrated to depths beyond the plow layer under irrigation, with transport behavior depending on soil moisture content and particle size.
