ClearSynergistic Effectsof Polystyrene Nanoplastics andCadmium on the Metabolic Processes and Their Accumulation in HydroponicallyGrown Lettuce (Lactuca sativa)
Hydroponically grown lettuce co-exposed to cadmium and polystyrene nanoplastics accumulated 61% more cadmium and more nanoplastics than singly-exposed plants, with combined exposure causing greater oxidative stress and growth inhibition.
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.
Potential synergistic effect of polystyrene nanoplastics on cadmium toxicity to Sedum alfredii Hance
**TLDR:** Scientists found that tiny plastic particles (nanoplastics) make the toxic metal cadmium even more dangerous when both pollutants are present in soil together. Plants exposed to both nanoplastics and cadmium absorbed much more of the poisonous cadmium than plants exposed to cadmium alone. This matters because these pollutants are increasingly common in our environment, and if plants take up more toxins, they could end up in our food supply.
[Effects of Polystyrene Microplastics Combined with Cadmium Contamination on Soil Physicochemical Properties and Physiological Ecology of Lactuca sativa].
Researchers studied the combined effects of polystyrene microplastics and cadmium contamination on soil properties and lettuce growth. The study found that the co-presence of microplastics and heavy metals altered soil physicochemical characteristics and affected plant physiological responses, indicating that compound contamination from microplastics and metals may pose greater risks to agricultural systems than either pollutant alone.
Coupled Effects of Polyethylene Microplastics and Cadmium on Soil–Plant Systems: Impact on Soil Properties and Cadmium Uptake in Lettuce
Researchers studied how polyethylene microplastics interact with cadmium contamination in soil and its effects on lettuce growth. The study found that microplastics combined with cadmium significantly decreased soil quality and that microplastics can alter cadmium uptake in plants, suggesting that co-contamination of agricultural soils with both pollutants may pose compounded risks to food crop safety.
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.
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.
Assessing stress responses in potherb mustard (Brassica juncea var. multiceps) exposed to a synergy of microplastics and cadmium: Insights from physiology, oxidative damage, and metabolomics
Researchers found that microplastics in soil increased the amount of cadmium, a toxic heavy metal, that mustard green plants absorbed, while also reducing crop yields and photosynthesis. Higher concentrations of microplastics made more cadmium available in the soil, leading to greater accumulation of the metal in the plants. This raises food safety concerns because vegetables grown in microplastic-contaminated soil could contain higher levels of toxic metals that are harmful to human health.
Phytotoxicity of binary nanoparticles and humic acid on Lactuca sativa L.
Polystyrene nanoplastics were found to aggravate the toxic effects of iron oxide nanoparticles on lettuce by inducing oxidative stress and root deformation, demonstrating synergistic phytotoxicity when two nanomaterial pollutants co-occur in soil.
Effect of co-presence of cadmium or procymidone with microplastic films in soil on lettuce growth
Pot experiments growing lettuce in soil contaminated with cadmium or the fungicide procymidone alongside LDPE or PVC microplastic films found that co-presence of microplastics with chemical contaminants produced subtle but measurable effects on plant growth. This matters because agricultural soils frequently contain both microplastics and chemical pollutants simultaneously, and their combined effects on food crops may differ from what single-contaminant studies would predict.
Mutual Effects and Uptake of Organic Contaminants and Nanoplastics by Lettuce in Co-Exposure
Researchers found that when lettuce was grown with both nanoplastics and common agricultural pollutants, the nanoplastics dramatically increased the amount of the painkiller ibuprofen absorbed into the plant's leaves (by up to 309% in salty conditions). This means nanoplastics in farm soil could act as carriers that boost how much of other harmful chemicals end up in the food we eat. The study highlights how microplastic contamination in agriculture can amplify human exposure to multiple pollutants at once.
Unveiling the impacts of biodegradable microplastics on cadmium toxicity, translocation, transformation, and metabolome in lettuce
Researchers studied how biodegradable microplastics interact with cadmium contamination in lettuce and found that the combination worsened the toxic effects on plant growth compared to cadmium alone. The biodegradable plastics increased cadmium accumulation in the edible parts of the lettuce and altered how the metal was distributed within plant cells. The findings raise concerns about using biodegradable plastic mulch in soils already contaminated with heavy metals, as it may increase the amount of toxic metals that end up in food crops.
Toxicity and fate of cadmium in hydroponically cultivated lettuce (Lactuca sativa L.) influenced by microplastics
Researchers found that PVC microplastics changed how lettuce plants absorb the toxic heavy metal cadmium when both were present in the growing water. The microplastics initially absorbed cadmium from the water but then altered the plant's uptake patterns, affecting where the metal accumulated in roots versus leaves. This matters because microplastics in agricultural water could change how toxic metals end up in the edible parts of vegetables people eat.
Microplastic-Mediated Heavy Metal Uptake in Lettuce (Lactuca sativa L.): Implications for Food Safety and Agricultural Sustainability
Researchers grew lettuce in contaminated soil mixed with different types of microplastics, including fibers, glitter, and fragments from bags and bottles. They found that microplastics altered how heavy metals like lead, cadmium, and copper moved through the soil and into the plants, sometimes increasing uptake of toxic metals in roots while decreasing others in leaves. The results raise concerns about food safety in agricultural areas where both microplastic and heavy metal contamination overlap.
Combined effects of microplastics and cadmium on the soil-plant system: Phytotoxicity, Cd accumulation and microbial activity
Researchers tested how different microplastic types combined with cadmium affect plant growth and soil health. Aged and biodegradable microplastics increased cadmium uptake in mustard greens more than fresh conventional plastics did. The study also found that microplastics altered soil microbial activity, suggesting that plastic pollution in farmland could change how plants absorb toxic metals from contaminated soil.
[Effects of Microplastics Coexisting in Vegetable Soil on the Change of Cadmium Bioavailability].
Researchers investigated the effects of biodegradable microplastics co-occurring with cadmium in vegetable soil through a 60-day pot experiment with lettuce, examining how the combined contamination alters cadmium bioavailability and uptake relative to cadmium-only or microplastic-only conditions.
Effects of naturally aged microplastics on arsenic and cadmium accumulation in lettuce: Insights into rhizosphere microecology
Researchers studied how naturally aged microplastics in soil affect the uptake of arsenic and cadmium by lettuce. At low concentrations, microplastics actually reduced heavy metal absorption and helped plant growth, but at higher concentrations they increased the amount of toxic metals taken up by the lettuce. This means microplastic-contaminated farmland could lead to higher levels of heavy metals in salad greens and other vegetables that people eat.
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.
Mechanistic Insights into the Effects of Aged Polystyrene Nanoplastics on the Toxicity of Cadmium to Triticum Aestivum
This study examined how aged polystyrene nanoplastics interact with the heavy metal cadmium to affect wheat plants. Researchers found that the aging process increases the nanoplastics' ability to absorb cadmium, which can alter how the metal is taken up by crops, raising questions about combined contaminant exposure through the food supply.
Synergistic effect of arsenate and microplastics and its toxicity mechanism on lettuce
Researchers investigated the combined effects of arsenate and polystyrene microplastics on lettuce growth. The study found that microplastics adsorbed arsenate from irrigation water and enhanced its uptake by lettuce, with the synergistic effect causing greater oxidative stress and growth inhibition than either contaminant alone.
Individual and Combined Effects of Nanoplastics and Cadmium on the Rhizosphere Bacterial Community of Sedum alfredii Hance
When polystyrene nanoplastics and cadmium co-occur in soil, they act synergistically to disrupt the bacterial community around plant roots (rhizosphere), reducing the diversity of beneficial bacteria by more than what either pollutant does alone. High concentrations of nanoplastics combined with cadmium significantly increased the availability of cadmium in soil by 4%, potentially increasing uptake by plants. This matters for both food safety — since Sedum alfredii is used in phytoremediation of heavy-metal-contaminated sites — and for understanding how combined pollution stresses affect soil health.
Antagonistic effect of polystyrene nanoplastics on cadmium toxicity to maize (Zea mays L.)
Researchers studied the combined effects of polystyrene nanoplastics and cadmium on maize plants and found that nanoplastics actually reduced cadmium toxicity. The study suggests that nanoplastics can adsorb cadmium and limit its uptake by plant roots, though both contaminants individually reduced plant growth and triggered oxidative stress responses.
