ClearRecent advances on microplastics/nanoplastics interaction with plant species: A concise review
This review synthesizes research on how microplastics and nanoplastics interact with plants, finding that plastic particles in soil can interfere with root uptake, germination, and crop yields depending on the type and concentration of plastic present. The findings are particularly relevant to human health because food crops grown in microplastic-contaminated agricultural soils may absorb or accumulate plastic particles, creating a direct dietary exposure route.
Effects of nano- & microplastics on terrestrial plants are ubiquitous and widespread: a systematic review
This systematic review finds that nano- and microplastics have widespread negative effects on plants, including reduced germination, stunted growth, and biochemical stress responses. Since plants form the base of our food supply, these findings suggest that microplastic contamination in agricultural soils could affect crop health and potentially the quality of food we eat.
A critical review of microplastics in the soil-plant system: Distribution, uptake, phytotoxicity and prevention
This review brings together data from over 1,000 sampling sites worldwide to map microplastic contamination in soil and its effects on plants. Microplastics can delay seed germination, stunt plant growth, inhibit photosynthesis, and cause genetic damage to crops. The findings raise concerns about food safety because microplastics in agricultural soil could both reduce crop yields and introduce contaminants into the food chain.
Formation, behavior, properties and impact of micro- and nanoplastics on agricultural soil ecosystems (A Review)
This review provides a comprehensive look at how micro and nanoplastics affect agricultural soil ecosystems, covering their sources, movement through soil, and impacts on soil organisms and crop growth.

Microplastics reduce the wheat (Triticum aestivum L.) net photosynthetic rate through rhizospheric effects
Microplastics were shown to reduce the net photosynthesis and growth of wheat plants, with effects increasing at higher plastic concentrations. This demonstrates that microplastic contamination in agricultural soils poses a direct threat to crop productivity and food security.
Environmental risk substances in soil on seed germination: Chemical species, inhibition performance, and mechanisms
This review summarizes how various soil pollutants including microplastics, heavy metals, and petroleum chemicals inhibit crop seed germination and early growth. Microplastics can physically block water absorption by seeds and release toxic additives that impair root development. The findings are relevant to food security because microplastic contamination of agricultural soil could reduce crop yields and affect the food supply.
Investigating the Impact of Microplastics Type of Polyethylene, Polypropylene, and Polystyrene on Seed Germination and Early Growth of Rice Plants
Researchers investigated how three common types of microplastics, polyethylene, polypropylene, and polystyrene, affect rice seed germination and early seedling growth. They found that microplastic exposure altered root development and shoot growth, with the effects varying by polymer type. The study raises concerns about how microplastic-contaminated agricultural soils could affect staple crop establishment and food production.
Micro/Nanoplastics in Agricultural Soils and Associated Hazard
This review surveys the sources, distribution, and hazards of micro- and nanoplastics in agricultural soils, with particular attention to how MPs interact with soil organisms, alter nutrient availability, and accumulate in crops in ways that threaten both soil health and food safety.
[Adverse Effects and Underlying Mechanisms of Soil Microplastics on Crops and Its Preventive Strategies].
This review summarizes the pollution status of microplastics in agricultural soils and their adverse effects on crops, including mechanical damage, oxidative stress, and genotoxicity leading to disrupted plant growth and metabolism. Researchers also examined how hazardous substances released from microplastics and contaminants adsorbed onto their surfaces contribute to soil ecosystem harm. The study identifies source control and biodegradation as the most promising strategies for reducing microplastic risks to crop production.
Particulate plastics-plant interaction in soil and its implications: A review
This review examines how micro- and nanoplastics in soil interact with plants, including uptake through roots, accumulation in plant tissues, and effects on growth, nutrient absorption, and soil microbial communities. The study highlights that these plastic particles can alter soil structure and chemistry in ways that affect crop development, raising concerns about food safety and agricultural productivity.
[Effects of Microplastics on the Growth, Physiology, and Biochemical Characteristics of Wheat (Triticum aestivum)].
Wheat seedlings were grown in soils spiked with 100 nm and 5 μm polystyrene microplastics, with high concentrations (200 mg/L) significantly inhibiting root and stem elongation, reducing chlorophyll, and altering antioxidant enzyme activity, with smaller nanoplastics showing greater toxicity. The findings demonstrate that microplastic size influences phytotoxicity in a major agricultural crop.
Microplastics in agroecosystems: A review of effects on soil biota and key soil functions
This review examines how microplastic and nanoplastic contamination in agricultural soils affects soil organisms and ecological functions. Researchers found that plastics enter farmland through multiple pathways including plastic mulch, sewage sludge, and irrigation water, and once present they alter soil properties and exhibit toxic behavior toward soil biota. The study identifies significant knowledge gaps about the long-term impacts of microplastic accumulation on agricultural productivity and food safety.
Microplastics and nanoplastics in the soil-plant nexus: Sources, uptake, and toxicity
This review examines how microplastics and nanoplastics accumulate in agricultural soils from plastic products and affect the soil-plant system.

The findings raise concerns about food safety since these particles may carry co-contaminants into the food chain.
Impacts of Microplastic Pollution on Soil Ecosystems and Agricultural Productivity
This comprehensive review synthesizes research on how microplastics accumulate in agricultural soils — through mulch films, sewage sludge, compost, irrigation water, and airborne deposition — and what happens once they are there. Evidence reviewed suggests microplastics impair seed germination, reduce plant water uptake, and may contribute to a projected 5–15% decline in crop yields over coming decades. Because farmland feeds the world and is increasingly contaminated with plastic particles, this review underscores an urgent need for limits on agricultural plastic use and better soil monitoring.
Effects of Microplastics on Germination and Seedlings Growth of Wheat (Triticum aestivum L.)
