ClearCan 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.
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.
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.

Researchers exposed Arabidopsis thaliana, peas, and maize to PET microparticles in hydroponic cultivation, finding that bacteria-sized PET particles caused severe toxic effects on plant growth, providing evidence that microplastic contamination poses a significant threat to agricultural crops even in the absence of soil or soil microbiota interactions.
The varied effects of different microplastics on stem development and carbon-nitrogen metabolism in tomato
Researchers tested how six different types of microplastics, including both conventional and biodegradable varieties, affect tomato plant growth. All types disrupted the plants' internal structure and altered how they processed carbon and nitrogen, with PVC causing the most severe damage. Notably, biodegradable plastics like PLA and PBS were not harmless either, suggesting that switching to so-called eco-friendly plastics may not fully protect agricultural soil and food crops from microplastic contamination.
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.
Impacts 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.
The effect of microplastic contaminated compost on the growth of rice seedlings
Researchers found that adding PET microplastics to compost significantly harmed rice seedling growth, reducing root length by 38%, plant height by 25%, and chlorophyll content by up to 55%. The microplastics appeared to interfere with nutrient uptake and photosynthesis. This is concerning because compost used in agriculture is often contaminated with plastic waste, which could reduce crop yields and potentially affect food quality.
Microplastics-induced plant stress in terrestrial ecosystems: Sources, transport, biological impacts, and remediation strategies
This review examines how microplastics enter and affect terrestrial ecosystems, noting that soil now harbors over 30% of global plastic waste. The study describes how microplastics are taken up by plants through roots and leaves, cause direct toxic, genotoxic, and indirect effects on plant growth, and interact with other soil contaminants, while also surveying remediation strategies and the use of machine learning for predicting microplastic effects.
Molecular mechanisms underlying microplastics-induced inhibition of lateral root development in tomato (Solanum lycopersicum L.)
Researchers investigated how PET microplastics affect tomato seedling root development and found that exposure significantly inhibited lateral root growth, reduced chlorophyll content, and impaired photosynthesis. The study revealed that microplastics triggered oxidative stress in root tips and disrupted auxin and abscisic acid hormone signaling pathways, suggesting these molecular mechanisms underlie the observed phytotoxicity.
Unraveling the impact of nano-microscale polyethylene and polypropylene plastics on Nicotiana tabacum: Physiological responses and molecular mechanisms
Researchers exposed tobacco plants to polyethylene and polypropylene microplastics of different sizes and found that both types suppressed plant growth in a dose-dependent manner, with polypropylene being more toxic. The microplastics disrupted photosynthesis, triggered oxidative stress, and altered hormone signaling and defense pathways in the plants. These findings demonstrate that microplastic contamination in soil can impair crop growth at the molecular level, potentially affecting agricultural productivity.
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.
Assessment of physiological stress on plants grown in soil contaminated with microplastics
Researchers tested how three types of microplastics (PET, HDPE, and polyester) affect the growth and health of spring onion and okra plants. They found that all microplastic types reduced chlorophyll levels, increased oxidative stress, and stunted plant growth, with HDPE and polyester causing the most damage. The study highlights the potential ecological risks microplastics pose to vegetable crops grown in contaminated soil.

Impact of polyvinyl chloride (PVC) microplastic on growth, photosynthesis and nutrient uptake of Solanum lycopersicum L. (Tomato)
Adding PVC microplastics to soil reduced tomato plant growth, photosynthesis, and nutrient uptake in a dose-dependent manner, even though no visible damage appeared on the leaves. At the molecular level, the microplastics disrupted genes and proteins involved in photosynthesis and nutrient absorption. This matters for food safety because microplastics in agricultural soils could reduce crop yields and potentially enter the food supply.
Nano- and Microplastics Increase the Occurrence of Bacterial Wilt in Tomato (Solanum lycopersicum L.)
