ClearCombined Phytotoxicity of Microplastics andLead on the Growth and Physio-BiochemicalCharacteristics of Tobacco (Nicotiana tabacum)
Researchers grew tobacco plants in soil contaminated with both polyethylene microplastics and lead, finding that the combination caused greater damage to photosynthesis and plant growth than either pollutant alone, while microplastics partially reduced how much lead roots absorbed. The study shows that microplastic and heavy metal co-contamination — increasingly common in agricultural soils — poses compounding risks to crop health.
Impact of Microplstic and Lead Toxicity on the Terrestrial Plants: a Critical Review
This review examines the toxic effects of microplastics and lead on terrestrial plants, synthesizing evidence that MPs modify soil physicochemical properties and enzymatic activity while lead disrupts root and shoot biomass, leaf development, and growth tolerance. Combined microplastic-lead exposure is found to be more damaging than either stressor alone, with implications for agricultural productivity in contaminated soils.
Effects of polypropylene microplastics and lead (Pb) contamination on soil properties and the growth response of Ficus Benjamina
Researchers found that polypropylene microplastics and lead contamination together cause greater harm to soil chemistry and plant growth than either contaminant alone, with Ficus plants showing significantly reduced leaf area, root length, and total biomass when exposed to both. Microplastics also lowered soil pH and depleted essential nutrients, compounding the toxic effects of the heavy metal.
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.
Interactive effects of polystyrene microplastics and Pb on growth and phytochemicals in mung bean (Vigna radiata L.)
Researchers studied the combined effects of polystyrene microplastics and lead on mung bean plants. They found that when both pollutants were present together, the damage was more severe, reducing plant weight, impairing photosynthesis, and disrupting chlorophyll production and enzyme activity. The study suggests that microplastics and heavy metals can interact to create amplified harmful effects on crop plants in contaminated agricultural environments.
Effects of microplastic and copper applications on chlorophyll and carotenoid contents in kale and tomato
Researchers investigated the individual and combined effects of microplastics and copper on kale and tomato plants, measuring impacts on chlorophyll and carotenoid pigment content to assess how co-contamination of agricultural soils affects crop physiology.
The Effects of Microplastics and Heavy Metals Individually and in Combination on the Growth of Water Spinach (Ipomoea aquatic) and Rhizosphere Microorganisms
Researchers tested how combinations of microplastics and heavy metals (cadmium and lead) affect the growth of water spinach and the microbial communities in its root zone. They found that all three stressors individually inhibited plant growth, and combining microplastics with heavy metals intensified the toxic effects while reducing the availability of essential soil nutrients. The study suggests that microplastic-heavy metal interactions in agricultural soils may pose compounding risks to both crop health and soil ecosystem function.
Combined toxicity of microplastic and lead on submerged macrophytes
Researchers tested the combined toxicity of microplastics and lead on two species of submerged aquatic plants over five days. They found that lead alone reduced photosynthetic pigments, chlorophyll fluorescence, and sugar content while increasing oxidative stress markers, and microplastics aggravated lead toxicity on certain parameters in a species-specific manner. The study suggests that microplastics may enhance heavy metal toxicity in aquatic plants, with effects varying between species.
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 Effects of Microplastic and Copper Treatments on the Number of Leaves, Stem, and Root Diameters in Tomato and Kale
This study examined the effects of microplastic and copper co-exposure on plant growth parameters — leaf number, stem diameter, and root morphology — in agricultural plant species. Both microplastics and copper alone reduced growth, and combined exposure caused greater inhibition, indicating synergistic phytotoxic effects in polluted agricultural soils.
Combined impact of short-term phosphorus deficiency and microplastic contamination on tomato mineral elements, chlorophyll fluorescence and root exudates
Researchers studied how phosphorus deficiency and microplastic contamination together affect tomato plants grown in hydroponic conditions. They found that while each stressor alone had measurable effects, the combination altered root exudate composition and mineral uptake in distinct ways. The study highlights that microplastics may interact with existing nutritional stresses to create compounding challenges for plant health.
Coexistence of microplastics and heavy metals in soil: Occurrence, transport, key interactions and effect on plants
This review examines how microplastics and heavy metals like lead, cadmium, and arsenic interact in soil, often creating combined toxic effects on plants that differ from either pollutant alone. These interactions are relevant to human health because contaminated crops can transfer both microplastics and heavy metals to people through the food supply.
Coupled effects of microplastics and heavy metals on plants: Uptake, bioaccumulation, and environmental health perspectives
This review examines how microplastics and heavy metals work together to harm plants when both are present in soil. Microplastics can absorb heavy metals like lead, cadmium, and arsenic, and when plants take up these contaminated particles, the combined toxic effect is worse than either pollutant alone. This is concerning for human health because crops grown in contaminated soil could carry both microplastics and concentrated heavy metals into the food supply.
Co-exposure to microplastics and soil pollutants significantly exacerbates toxicity to crops: Insights from a global meta and machine-learning analysis
A large-scale analysis of 68 studies found that when microplastics combine with other soil pollutants, the harm to crops is significantly worse than from the other pollutants alone. Microplastics intensified damage to plant growth, increased oxidative stress, and reduced photosynthesis efficiency. Interestingly, microplastics did reduce the amount of other pollutants that accumulated in the crops, but the overall toxic effects on plant health were still greater.
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 combined microplastics and heavy metals pollution on terrestrial plants and rhizosphere environment: A review
This review summarizes how microplastics and heavy metals interact in soil to affect plant growth and the surrounding ecosystem. When present together, these pollutants cause significantly more harm than either alone, reducing plant weight by up to 87.5% and altering how heavy metals accumulate in crops -- raising concerns about food safety and human exposure through contaminated agricultural products.
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.
[Effects of Combined Pollution of Microplastics and Lead on Maize Seed Germination and Growth].
Researchers grew maize seeds in water spiked with lead and three common microplastics (polyethylene, polypropylene, and PVC) to test their combined effects on germination and early growth. All three plastics individually inhibited germination to varying degrees, but when combined with lead the effects were generally antagonistic — meaning the mixture was less toxic than each pollutant alone. These findings are important for understanding real-world soil contamination, where microplastics and heavy metals often co-occur in agricultural environments.
Synergistic modulation of Lead (II) bioavailability by polyethylene terephthalate microplastics and insights into assimilation kinetics in Canna indica
Scientists found that tiny plastic particles (microplastics) in soil can make plants absorb up to 250% more lead, a toxic heavy metal that's harmful to humans. This happens because the plastic pieces act like a delivery system, carrying more lead into plants that we might eventually eat. This research suggests that areas with plastic pollution in the soil could pose greater health risks than previously thought, especially for crops grown in contaminated areas.
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.
