ClearTranscriptome mechanisms of dandelion under stress of polystyrene and dibutyl phthalate and quantitative tracing of nanoplastics
Researchers traced how polystyrene nanoplastics move through dandelion roots via apoplastic pathways and the xylem, finding that co-exposure with the plasticizer dibutyl phthalate reduces particle accumulation but increases translocation to shoots, while transcriptomics revealed disruption of photosynthesis and hormone signaling pathways.
Effect of cadmium and polystyrene nanoplastics on the growth, antioxidant content, ionome, and metabolism of dandelion seedlings
This study examined how polystyrene nanoplastics interact with cadmium, a toxic heavy metal, and found that the combination worsened the toxic effects on dandelion seedlings beyond what either pollutant caused alone. The findings highlight that nanoplastics can change how heavy metals behave in the environment, potentially increasing the amount of toxic metals that enter the food chain through contaminated plants.
Nanoplastic and phthalate induced stress responses in rhizosphere soil: Microbial communities and metabolic networks
This study looked at how nanoplastics and a common plasticizer chemical (DBP) together affect the soil around dandelion roots, finding that the combination reduced soil quality and reshaped the communities of bacteria and fungi. The disruption of soil microbes and their chemical processes matters because it can affect the safety and quality of plants used for food and medicine.
Synergistic Effects of Polystyrene Nanoplastics and Cadmium on the Metabolic Processes and Their Accumulation in Hydroponically Grown Lettuce (Lactuca sativa)
When lettuce was grown with both nanoplastics and the toxic metal cadmium, the plants absorbed 61-67% more of both contaminants compared to exposure to either one alone. The combined pollution triggered a stronger stress response in the plants and changed how they grew. This is concerning for human health because it means nanoplastics in agricultural soil could significantly increase the amount of toxic heavy metals that end up in salad greens and other food crops.
Effects of polyethylene and biodegradable microplastics on the physiology and metabolic profiles of dandelion
Researchers compared how conventional polyethylene and two "biodegradable" plastic alternatives affected dandelion plants when mixed into soil. All three types of microplastics stunted plant growth and caused oxidative stress, with conventional polyethylene being the most toxic -- showing that even so-called biodegradable plastics can harm plant health and soil ecosystems.
Polystyrene nanoplastics distinctly impact cadmium uptake and toxicity in Arabidopsis thaliana
In a study using the model plant Arabidopsis, polystyrene nanoplastics increased the uptake and accumulation of the toxic heavy metal cadmium in plant roots. The combined stress of nanoplastics and cadmium caused worse oxidative damage and growth problems than either pollutant alone. This is concerning because it means microplastics in agricultural soil could help toxic metals get into crops more easily, potentially increasing human exposure through food.
The combined effects of nanoplastics and dibutyl phthalate on Streptomyces coelicolor M145
Researchers examined the combined toxicity of nanoplastics and the plasticizer dibutyl phthalate on Streptomyces coelicolor, finding that their co-exposure produces different effects than either contaminant alone, highlighting concerns about combined plastic-related pollution.
Carrier effects of microplastics in a hydroponic system: Amplifying diethyl phthalate toxicity and endophytic dysbiosis in Rye (Secale cereale L.) with implications for aquatic ecosystems
Researchers found that polystyrene microplastics and diethyl phthalate (a common plasticizer) interact synergistically to cause severe toxicity in hydroponically grown rye, far exceeding the damage from either pollutant alone. The study revealed a bidirectional mechanism where microplastics adsorb the plasticizer while the plasticizer enhances microplastic uptake by roots, leading to photosynthetic collapse and disrupted endophytic microbial communities.
Single and combined toxicity of polystyrene nanoplastics and PCB-52 to the aquatic duckweed Spirodela polyrhiza
Researchers found that polystyrene nanoplastics and PCB-52 act synergistically to impair the aquatic plant Spirodela polyrhiza, with combined exposure amplifying oxidative stress, chlorophyll loss, and osmotic imbalance in roots beyond what either pollutant caused alone — while low nanoplastic doses alone mildly stimulated growth.
Effects of polyethylene microplastic on the phytotoxicity of di-n-butyl phthalate in lettuce (Lactuca sativa L. var. ramosa Hort)
Researchers investigated how polyethylene microplastics interact with the chemical pollutant di-n-butyl phthalate in lettuce and found that microplastics altered the plant's response to the toxin. The combination reduced photosynthesis, lowered chlorophyll content, and disrupted the plant's antioxidant defenses. The study highlights that microplastics in soil can change how plants respond to other contaminants, potentially compounding environmental harm.
Combined toxicity influence of polypropylene microplastics and di-2-ethylhexyl phthalate on physiological-biochemical characteristics of cucumber (Cucumis sativus L.)
Researchers investigated the combined effects of polypropylene microplastics and the plasticizer DEHP on cucumber seedling health. They found that microplastics alone impaired photosynthesis and cell membrane stability, while DEHP individually also caused stress responses, but the mixture of both pollutants together produced more complex effects on the plants' antioxidant defenses. The study suggests that the co-presence of microplastics and plastic additives in agricultural soil may pose compounding risks to crop development.
Evaluating the role of soil EPS in modifying the toxicity potential of the mixture of polystyrene nanoplastics and xenoestrogen, Bisphenol A (BPA) in Allium cepa L.
This study examined how nanoplastics and the industrial chemical BPA interact in soil, finding that their combined effects on plant cells were worse than either pollutant alone. Positively charged nanoplastics paired with BPA caused the most damage, including cell death, oxidative stress, and chromosomal abnormalities in onion root cells. The findings suggest that the real-world mix of nanoplastics and chemicals in soil may be more harmful to crops than studies of individual pollutants indicate.
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.
Combined transcriptome and metabolome analysis revealed the toxicity mechanism of individual or combined of microplastic and salt stress on maize
Researchers studied how polystyrene microplastics combined with salt stress affect maize seedlings, finding that the combination reduced plant growth by nearly 74%, far worse than either stressor alone. Gene and metabolite analysis revealed that the combined stress severely disrupted energy production, antioxidant defenses, and hormone signaling in the plants. This is relevant to food security because microplastic-contaminated agricultural soils with high salt levels could dramatically reduce crop yields.
The interfacial interaction between Dechlorane Plus (DP) and polystyrene nanoplastics (PSNPs): An overlooked influence factor for the algal toxicity of PSNPs
Researchers investigated how a flame retardant chemical called Dechlorane Plus interacts with polystyrene nanoplastics and found that the two pollutants bind together and become more harmful to algae than either one alone. When exposed to both contaminants simultaneously, algae showed reduced photosynthesis, greater growth inhibition, and significantly increased oxidative damage. The study suggests that the combined effects of nanoplastics and their chemical additives pose greater environmental risks than previously recognized.
Combined interactions and ecotoxicological effects of micro/nanoplastics and organic pollutants in soil–plant systems: a critical overview
This review examines how micro- and nanoplastics interact with organic pollutants in soil-plant systems. The study highlights that these plastic particles can act synergistically with organic pollutants in terrestrial ecosystems, posing combined threats to soil and plant health that warrant further investigation.
Combined 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.
Titanium dioxide nanoparticles enhance the detrimental effect of polystyrene nanoplastics on cell and plant physiology of Vicia lens (L.) Coss. & Germ. seedlings
Combined exposure of Vicia lens seedlings to polystyrene nanoplastics and titanium dioxide nanoparticles caused greater physiological and cellular damage than either contaminant alone, suggesting synergistic toxicity at the plant level.
Single and combined effects of polystyrene nanoplastics and Cd on submerged plants Ceratophyllum demersum L.
Researchers studied the combined effects of nanoplastics and cadmium, a toxic heavy metal, on the aquatic plant Ceratophyllum demersum. They found that nanoplastics worsened cadmium's harmful effects on plant growth, photosynthesis, and cellular health, reducing growth rates by over 35%. The study suggests that when nanoplastics and heavy metals co-occur in water, their combined impact on aquatic plants may be more severe than either pollutant alone.
Dynamics of accumulation and multilevel biological effects of various alkyl chain phthalates and microplastics in rye: New insights into individual, physiological, and molecular perspectives
Researchers studied the combined toxicity of three phthalate esters with different alkyl chain lengths and polystyrene microplastics on rye plants, finding that MP presence amplified the phytotoxicity of longer-chain phthalates. The results demonstrate that microplastics can act as carriers that enhance the uptake and toxicity of co-occurring chemical contaminants in crops.
