ClearImpacts of Microplastics and Nanoplastics on Tomato Crops: A Critical Review
This review covers the impacts of microplastics and nanoplastics on tomato crops, documenting disruption at germination, root development, flowering, and fruit production stages. It also examines how these particles alter soil microbial communities and identifies priority research areas for understanding MP effects on major food crops.
Phytotoxicity of polystyrene, polyethylene and polypropylene microplastics on tomato (Lycopersicon esculentum L.)
Researchers tested the effects of polystyrene, polyethylene, and polypropylene microplastics on tomato plant growth using hydroponic experiments at various concentrations. The study found that all three types of microplastics negatively affected seed germination, root growth, and plant development, with effects varying by plastic type and concentration. These findings suggest that microplastic contamination in agricultural settings could interfere with crop growth and food production.
Presence of High-Density Polyethylene Nanoplastics (HDPE-NPs) in Soil Can Influence the Growth Parameters of Tomato Plants (Solanum lycopersicum L.) at Various Stages of Development
Researchers grew tomato plants in soil spiked with high-density polyethylene nanoplastics at environmentally relevant concentrations, finding that the nanoplastics slowed germination, reduced root and shoot growth, and affected plant physiology at multiple developmental stages. Effects were dose-dependent and more pronounced at higher nanoplastic concentrations. As nanoplastics are now detected in agricultural soils through biosolid application and irrigation, this study raises concerns about the impact of nano-sized plastic contamination on food crop yields.
Mechanistic insights into the size-dependent bioaccumulation and phytotoxicity of polyethylene microplastics in tomato seedlings
Researchers investigated how polyethylene microplastics of different sizes affect tomato seedlings and found that the smallest particles (1-50 micrometers) caused the most severe damage, reducing shoot weight by 42.3% and root length by 55.1%. The study revealed that microplastic uptake and toxicity are strongly size-dependent, with smaller particles more easily absorbed and translocated through plant tissues, triggering significant oxidative stress.
Effects of microplastics polluted soil on the growth of Solanum lycopersicum L.
This study tested how microplastic-contaminated soil affects tomato plant growth, finding that higher concentrations of plastic particles in soil reduced plant height, root development, and overall crop health. The results suggest that microplastic pollution in farmland could reduce food crop yields and potentially affect the quality of the produce we eat.
Effects of polystyrene nanoplastics on tomato plant growth, fruit yield and quality
Researchers investigated how polystyrene nanoplastics affect tomato plant growth and fruit quality, finding that exposure reduced seedling biomass, impaired photosynthesis, and triggered oxidative stress. At higher concentrations, the nanoplastics inhibited mineral uptake and diminished fruit yield along with nutritional quality markers like vitamin C and lycopene. The study highlights that nanoplastic contamination in agricultural soils could pose a meaningful threat to food crop productivity and nutritional value.
Nano- and microplastics commonly cause adverse impacts on plants at environmentally relevant levels: A systematic review
Systematic review of 78 studies found that nano- and microplastics commonly cause adverse effects on plants even at environmentally relevant concentrations, with germination and root growth more strongly affected than shoot growth during early development. Chlorophyll levels were consistently reduced while stress indicators (ROS) and antioxidant enzymes were consistently upregulated across species.
Microplastics in Crop Systems
This chapter reviews the uptake, translocation, and phytotoxic effects of micro- and nanoplastics in crop systems, synthesizing evidence on how particle size, polymer type, and concentration affect plant growth, nutrient uptake, and food safety.
Nano- and Microplastics Increase the Occurrence of Bacterial Wilt in Tomato (Solanum lycopersicum L.)
This study found that tiny nano- and microplastic particles in soil made tomato plants significantly more vulnerable to bacterial wilt disease. The smallest nanoplastics (30 nm) more than doubled the disease rate by disrupting the plant's immune defenses and altering soil bacteria, raising concerns about how plastic pollution in farmland could threaten food crop health.
Polyethylene nanoplastics affected morphological, physiological, and molecular indices in tomato (Solanum lycopersicum L.)
Polyethylene nanoplastics in soil caused significant damage to tomato plants, including reduced growth, delayed flowering, lower fruit quality, and changes in DNA methylation patterns. Even at low concentrations, the nanoplastics triggered oxidative stress and altered gene expression in the plants. These findings raise concerns about food safety because nanoplastic contamination in farm soil could reduce both the yield and nutritional quality of tomatoes and potentially other food crops.
Visual Trackingand Quantitative Analysis of PolystyreneNanoplastics Uptake and Transport across Various Tomato Varieties
Researchers tracked uptake and transport of polystyrene nanoplastics across six tomato cultivars, finding significant varietal differences in accumulation and growth inhibition, with Heinz 1706 being most resistant (13% inhibition) and Moneymaker most sensitive (32% inhibition). Nanoplastics accumulated preferentially in roots and near the xylem in stems and leaves, with shoot concentrations substantially lower than root concentrations.
A Combined Effect of Mixed Multi-Microplastic Types on Growth and Yield of Tomato
A greenhouse experiment found that a 1% w/w mixture of polyethylene, polystyrene, and polypropylene microplastics negatively affected tomato plant development and yield, with statistical analysis confirming significant growth reductions compared to uncontaminated soil.
The multifaceted mechanisms of microplastic inhibition of tomato plant growth: oxidative toxicity, metabolic perturbation, and photosynthetic damage
Researchers exposed tomato seedlings to biodegradable and conventional microplastics and investigated photosynthetic performance, metabolic disruption, and oxidative stress responses. Both microplastic types inhibited tomato growth and caused oxidative damage, with impacts on the photosynthetic apparatus and metabolite profiles, challenging the assumption that biodegradable plastics are safer for agricultural systems.
Microplastic/nanoplastic toxicity in plants: an imminent concern
This review examines the growing body of research on how microplastics and nanoplastics affect terrestrial plants, from root uptake to changes in growth and gene expression. Researchers found that these particles can alter plant physiology and biochemistry at varying degrees depending on particle size and concentration. The study calls for more research on how plastic contamination in soil may ultimately affect food crop quality and human health through the food chain.
Phytotoxic effects of plastic pollution in crops: what is the size of the problem?
This review examines the phytotoxic effects of nano- and microplastics on crop species, summarizing research conducted since the field emerged in 2016. Researchers found that plastic particles can damage plant tissues through both direct and indirect mechanisms, and that nanoplastics can enter plant cells and accumulate in edible organs. The study notes that contradictory results across studies make it difficult to draw firm conclusions, pointing to the need for more standardized research approaches.

Micro- and nano-plastics in hydroponic environment are critical for plants: A meta-analysis
This meta-analysis pools data from multiple studies to evaluate how microplastics and nanoplastics affect plants grown in water-based growing systems. The findings show that these plastic particles can reduce plant growth and alter root function, suggesting that even hydroponic produce may not be free from microplastic contamination concerns.
The Effect of Humic Acid and Polystyrene Fluorescence Nanoplastics on Solanum lycopersicum Environmental Behavior and Phytotoxicity
Exposure of tomato seedlings to polystyrene fluorescent nanoplastics (100 nm) with and without humic acid showed that humic acid formed an eco-corona on nanoplastic surfaces, increasing their hydrodynamic size. The combination of nanoplastics and humic acid affected seed germination and plant growth more than either alone, demonstrating how environmental organic matter modifies nanoplastic behavior.
