Quartz sand surface-bound rice root exudates decreased the transport of microplastics in porous media
Summary
Researchers investigated how rice root exudates bound to quartz sand surfaces affect the transport of microplastics through soil, finding that root exudate coatings on sand grains significantly reduced microplastic mobility. The results suggest plant root activity shapes microplastic fate and transport in agricultural soils.
Quartz sand surface-bound root exudates could decrease the transport of MPs in porous media, due to the lower DLVO energy barrier between MPs and quartz sand covered with root exudates.

Effects of neonicotinoid insecticides on transport of non-degradable agricultural film microplastics
Researchers investigated how neonicotinoid insecticides adsorb onto agricultural film microplastics and affect their transport through porous media, finding that neonicotinoids altered microplastic mobility in ways that could influence contaminant spread in farmland soils.
Processes controlling the transportation of microplastics in agricultural soils
Researchers investigated the physical processes controlling microplastic transport through agricultural soils, examining how soil structure, water flow, bioturbation, and particle properties interact to move microplastics from surface application sites deeper into the soil profile or laterally toward aquatic systems. The study addressed the dual role of agricultural soils as both sinks and potential sources of microplastic pollution to surrounding environments.
Root traits and rhizosphere responses as emerging bioindicators of microplastic pollution in agricultural soils: A review
This review examines how microplastic pollution in agricultural soils disrupts root growth, nutrient uptake, and the beneficial interactions between plant roots and soil microbes. Researchers found that microplastics can alter root exudation patterns, change soil structure, and shift microbial communities around roots in ways that may impair crop productivity. The study proposes that root traits and rhizosphere responses could serve as early warning indicators of microplastic contamination in farmland.
Micro- and nanoplastics retention in porous media exhibits different dependence on grain surface roughness and clay coating with particle size
Researchers found that grain surface roughness and clay coatings affect the retention of microplastics and nanoplastics in porous media differently depending on particle size, with nanoplastics behaving oppositely to microplastics in certain soil conditions — complicating predictions of plastic transport in groundwater systems.
The individual transport, cotransport and immobilization with solar pyrolysis biochar of microplastics and plasticizer in sandy soil
Researchers tracked the individual transport, co-transport, and immobilization of microplastics in porous media, finding that plastic particle behavior differs significantly depending on surface charge and pore structure interactions. The results improve predictions of where microplastics migrate and accumulate in soils and aquifers.
