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.
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.
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.
Polyester microplastic fibers in soil increase nitrogen loss via leaching and decrease plant biomass production and N uptake
Researchers found that polyester microplastic fibers in soil increased nitrogen loss via leaching by up to 300% while decreasing plant biomass production and nitrogen uptake in maize, demonstrating significant disruption to agroecosystem nutrient cycling.
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.

Effects of polyester microfibers on soil physical properties: Perception from a field and a pot experiment
Polyester microfiber additions to clayey soil at 0.1% and 0.3% concentrations in field and pot experiments significantly increased large pore volume (>30 μm) and reduced small pore volume (<30 μm) but did not affect bulk density or saturated hydraulic conductivity. The findings indicate that polyester microfibers alter soil pore structure in ways that could influence water retention and plant-available water in agricultural soils.
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.
Effect of polypropylene microplastics on seed germination and nutrient uptake of tomato and cherry tomato plants
Researchers tested the effects of polypropylene microplastics on tomato and cherry tomato seed growth in lab conditions. While microplastics did not significantly affect germination, they did alter how plants absorbed certain nutrients like potassium and calcium. This suggests that microplastic-contaminated soil could subtly change the nutritional quality of food crops, even if the plants appear to grow normally.
