ClearPolyethylene 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.
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.
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.
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.
Phytotoxic Effects of Treated Wastewater Used for Agricultural Irrigation On Root Hydraulic Conductivity and Plant Growth

Researchers examined variability in microplastic abundance and bisphenol A contamination alongside antioxidant protein responses in marine organisms, finding that combined chemical exposure induced stronger oxidative stress responses than MPs or BPA alone.
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.
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.
The effects of Micro/Nano-plastics exposure on plants and their toxic mechanisms: A review from multi-omics perspectives.
A multi-omics review of micro/nanoplastic effects on plants found that plastic exposure disrupts gene expression, protein function, and metabolic pathways across multiple plant systems, with potential consequences for crop yield and agricultural food safety.
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.
Phytotoxic effects of treated wastewater used for agricultural irrigation on root hydraulic conductivity and plant growth
Researchers conducted hydroponic experiments to test the phytotoxic effects of treated wastewater on root hydraulic conductance in maize seedlings, finding that pressurized water flow through excised roots was reduced by 25-52% within 90 minutes of exposure. The study identified wastewater components that impair plant water transport capacity when agricultural irrigation uses treated effluent.
MICROPLÁSTICOS Y NANOPLÁSTICOS: UNA REVISIÓN SISTEMÁTICA DE SU IMPACTO EN EL CRECIMIENTO DE TOMATE (Solanum lycopersicum)
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.
The effect of sewage sludge containing microplastics on growth and fruit development of tomato plants
Sewage sludge containing microplastics was applied to soil and effects on tomato plant growth and fruit development were assessed. Microplastic exposure through sludge-amended soil altered vegetative growth and fruit maturation, suggesting that agricultural sludge application is a route by which microplastics affect food crops.
Looking into the effects of co-contamination by micro(nano)plastics in the presence of other pollutants on irrigated edible plants
This review examines the combined effects of micro- and nanoplastics with other pollutants found in treated wastewater used for crop irrigation. Researchers analyzed 19 studies and found that the joint exposure to plastics and contaminants like heavy metals or pesticides often produced different toxicity outcomes than either pollutant alone. The findings suggest that using reclaimed wastewater for irrigation may expose food crops to complex mixtures of pollutants whose combined effects are still poorly understood.
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.
Can RhizosphereEffects Mitigate the Threat from Nanoplasticsand Plastic Additives to Tomato (Solanum lycopersicum L.)?
Researchers used a root-box system to examine how nanoplastics and the plasticizer DEHP interact in the rhizosphere of tomato plants, finding that DEHP dominated the plastic pollution risk to plants and that nanoplastic co-exposure did not mitigate DEHP toxicity to soil microorganisms but increased it for food safety.
Influence of bisphenol A concentration on organic matter removal and nitrification in biological wastewater treatment
Laboratory wastewater treatment experiments found that Bisphenol A (BPA), a plasticizer that leaches from many plastics, disrupted nitrification — the key microbial process that removes ammonia from wastewater — at concentrations of 10 mg/L by reducing populations of the nitrifying bacterium Nitrosomonas. Because wastewater treatment plants are critical for protecting water quality, these results highlight how plastic-derived chemical pollution can impair the very infrastructure designed to clean contaminated water.
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.

Transcriptomic and metabolomic changes in lettuce triggered by microplastics-stress
Researchers grew lettuce in water containing polystyrene microplastics and found that the particles accumulated in root tips and leaf veins, causing water loss stress and changes in gene expression. The plants responded by activating stress defense systems and altering their metabolism, including increased production of protective compounds in root secretions. This study provides molecular-level evidence that microplastics can stress food crops and change their biology, raising questions about the safety and nutritional quality of vegetables grown in contaminated environments.

This comprehensive review examines how microplastics enter plant systems, the physiological and biochemical impacts on plant health, and the implications for crop productivity and food safety, synthesizing evidence that MPs can reduce germination, growth, and nutritional quality in agricultural plants.
Brassinosteroids alleviate nanoplastic toxicity in edible plants by activating antioxidant defense systems and suppressing nanoplastic uptake
Scientists discovered that nanoplastics accumulate in the edible parts of tomato plants, but treating the plants with a natural hormone called brassinosteroids reduced nanoplastic uptake and reversed the growth damage. The hormone works by turning off water-channel genes that nanoplastics use to enter the plant. This finding matters for food safety because it suggests a practical way to reduce the amount of nanoplastics people consume through fruits and vegetables.
Bisphenol A exposure modulates ovarian cancer gene expression and oxidative stress markers: a case-control study.
In a case-control study at Cairo's National Cancer Institute, researchers measured bisphenol A (BPA) levels and oxidative stress markers in 30 ovarian cancer patients versus 30 healthy controls. Patients had higher urinary BPA, elevated reactive oxygen species, lower antioxidant enzyme activity, and altered KRT4 gene expression, linking BPA exposure to molecular changes associated with ovarian cancer.
