This review examined how plants take up and accumulate microplastics from contaminated soil, finding that plastics can disrupt soil microbial communities, reduce nutrient availability, and impair plant growth. The uptake of microplastics by edible crops raises concerns about food chain transfer to humans, since the particles can carry toxic pollutants like persistent organic compounds and heavy metals.
Microplastic Uptake in Vegetables: Sources, Mechanisms, Transport and Food Safety
This review summarizes current knowledge on how microplastics enter vegetables through soil, water, and air, and how they are transported within plant tissues. Researchers found that microplastics can be taken up through roots and move to edible parts, with uptake varying by plant species, particle size, and soil conditions. The findings highlight that vegetable consumption may be an important but underrecognized pathway for human microplastic exposure.
Nanoplastics are taken up by lettuce and barley under realistic soil condition
Scientists found that tiny plastic particles called nanoplastics can be absorbed by lettuce and barley plants when grown in soil, even at low pollution levels similar to what's found in the environment. The plastic particles accumulated in the parts of the plants that people eat, showing a new way these pollutants could enter our food supply. While the amounts were small, this research reveals that nanoplastics from pollution can travel from soil into our crops, which could eventually affect human health.
The hidden impacts of micro/nanoplastics on soil, crop and human health
This review examines the chain of impacts from micro- and nanoplastics in soil through crop uptake to potential human health effects. Researchers found that these tiny particles can stick to plant roots, enter crop tissues, and carry toxic chemicals along with them. The study highlights that this soil-to-plate pathway is still poorly understood and calls for more research into how agricultural microplastic contamination may affect the food we eat.
Impacts of microplastics on terrestrial plants: A critical review
This review examines how microplastics affect land-based plants, finding that they can alter soil structure, disrupt beneficial soil microbes, and reduce plant growth. Microplastics also carry toxic chemicals like plasticizers and heavy metals that can be taken up by plant roots and enter the food chain. The findings raise concerns about human health since contaminated crops could be a hidden source of microplastic and chemical exposure in our diets.
A Systematic Review on Emission, Accumulation, Mechanism, and Toxicity Perspective of Micro‐Nanoplastics in the Soil–Plant Nexus
This systematic review examines how micro- and nanoplastics enter soil, accumulate in plants, and move through the soil-plant system. The research shows that microplastics alter soil properties, affect plant growth, and can be taken up by crop roots and transported to edible plant parts. This is a direct concern for human health because it means microplastics in agricultural soil may end up in the fruits and vegetables people consume.
Assessing the impact of micro and nanoplastics on the productivity of vegetable crops in terrestrial horticulture: a comprehensive review
This review summarizes research on how micro and nanoplastics accumulate in farmland and get absorbed by vegetable crops through their roots, building up in the edible parts of the plants. The plastic particles cause toxic effects that stunt plant growth by disrupting cellular processes and gene activity. This means the vegetables people eat may contain microplastics picked up from contaminated soil.

Uptake and accumulation of microplastics in an edible plant
Researchers demonstrated for the first time that edible plants can take up and accumulate microplastics from soil. Using fluorescently labeled polystyrene beads, they showed that 0.2-micrometer particles entered lettuce roots through small cracks at lateral root emergence sites, traveled through the vascular system, and accumulated in the leaves. The findings raise concerns about a previously unrecognized pathway for human microplastic exposure through the consumption of vegetables grown in contaminated soil.
