ClearPhytotoxicity 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.
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.
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.
Can microplastics threaten plant productivity and fruit quality? Insights from Micro-Tom and Micro-PET/PVC
Researchers grew tomato plants in soil containing environmentally realistic levels of PET and PVC microplastics and found mixed effects on plant productivity and fruit quality. While some growth parameters were affected, the microplastics also altered the mineral content of the tomatoes. This study suggests that microplastics in agricultural soil could change the nutritional profile of the food we eat.
A Combined Effect of Mixed Multi-Microplastic Types on Growth and Yield of Tomato
Researchers grew tomatoes in soil spiked with a mixture of polyethylene, polystyrene, and polypropylene microplastics and found that while the plants appeared to grow normally, the nutritional quality of the fruit changed. Microplastics significantly reduced carotenoids, flavonoids, and sugars in the tomatoes while increasing protein and certain stress-related enzymes. This suggests that even when crops look healthy, microplastics in soil could subtly reduce the nutritional value of the food we eat.

Impact of Polystyrene Microplastics on Soil Properties, Microbial Diversity and Solanum lycopersicum L. Growth in Meadow Soils
Researchers tested how polystyrene microplastics of different sizes and concentrations affect tomato plant growth and soil microbes. Surprisingly, some microplastic treatments boosted plant growth and soil nutrients, while others reduced microbial diversity and disrupted soil community networks. The mixed results show that microplastic effects on agriculture are complex and depend on particle size and concentration, making it difficult to predict how contaminated soil will affect food crops.
Physiological and biochemical effects of polystyrene micro/nano plastics on Arabidopsis thaliana
Experiments on the model plant Arabidopsis showed that polystyrene nano- and microplastics reduced seed germination, stunted growth, lowered chlorophyll levels, and triggered oxidative stress in roots, with smaller particles and higher concentrations causing the most damage. These findings raise concerns about how microplastic contamination in agricultural soil could affect crop health and ultimately food production.

This systematic review analysed published studies on the effects of synthetic microplastics and nanoplastics on tomato (Solanum lycopersicum) growth, examining how polymer type, particle size, concentration, and growth medium modulate phytotoxicity. The review found that MP and NP exposure consistently impaired biomass accumulation, plant height, flower and fruit production, and root and shoot length, with higher concentrations and smaller particle sizes generally producing the most pronounced negative effects.
Foliar implications of polystyrene nanoplastics on leafy vegetables and its ecological consequences
Scientists applied polystyrene nanoplastics to four common leafy vegetables and found that the tiny particles accumulated on leaf surfaces, particularly around the pores plants use to breathe. This accumulation reduced the plants' chlorophyll content and ability to photosynthesize, affecting their growth and nutritional quality. The findings raise concerns that airborne nanoplastic pollution could compromise the safety and nutritional value of the vegetables people eat.
Foliar-applied polystyrene nanoplastics (PSNPs) reduce the growth and nutritional quality of lettuce (Lactuca sativa L.)
When lettuce plants were exposed to polystyrene nanoplastics sprayed on their leaves, they grew significantly smaller and produced less nutritious food, with reduced essential amino acids and micronutrients. The nanoplastics were absorbed through leaf pores and could travel down to the roots, causing oxidative stress throughout the plant. This study warns that airborne nanoplastic pollution could reduce both the quantity and nutritional quality of food crops.
