ClearEffect 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.
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.
Combined Exposure to Polyethylene Microplastics and Copper Affects Growth and Antioxidant Responses in Rice Seedlings
Researchers exposed rice seedlings to polyethylene microplastics and copper both individually and in combination and found that microplastics significantly enhanced copper uptake, increasing accumulation by about 25% compared to copper alone. While microplastics alone had minimal effects on growth, the combined exposure intensified oxidative stress in roots and altered antioxidant defense responses. The study demonstrates that microplastics can increase the bioavailability and toxicity of heavy metals in agricultural crop systems.
Effects of polyethylene microplastics and heavy metals on soil-plant microbial dynamics
This study examined how polyethylene microplastics interact with heavy metals in soil and found that microplastics significantly reduced plant growth while altering soil enzyme activity and microbial communities. The combination of microplastics and heavy metals disrupted nutrient cycling in the soil in ways that were different from either pollutant alone. These findings suggest that microplastic contamination in agricultural soil could affect crop nutrition and food production.
Effects of co-exposure of antibiotic and microplastic on the rhizosphere microenvironment of lettuce seedlings
Researchers examined how the combination of antibiotics and polyethylene microplastics in agricultural soil affects lettuce seedling growth and the microbial community around plant roots. They found that combined exposure altered soil bacterial diversity, changed the chemical profile of root-zone metabolites, and affected nutrient cycling differently than either contaminant alone. The study highlights the compounding environmental risks when antibiotics from animal manure and microplastics from plastic films co-exist in farmland soils.
Effects of Polypropylene Microplastics and Copper Contamination on Rice Seedling Growth
Researchers studied how polypropylene microplastics and copper contamination individually and jointly affect rice seedling growth in hydroponic conditions. The study found that microplastics alone slightly promoted growth, while copper inhibited it, and the combination reduced copper accumulation in seedlings compared to copper alone, suggesting complex interactions between these pollutants in agricultural settings.
Interactive impacts of microplastics and arsenic on agricultural soil and plant traits
This study tested how microplastics interact with arsenic, a toxic metal, in agricultural soil growing lettuce. While microplastics alone slightly promoted plant growth, combining them with arsenic significantly reduced lettuce size and health. The findings suggest that microplastics in farm soil could worsen the effects of other pollutants like arsenic, potentially affecting the safety and quality of leafy vegetables that people eat.
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.
Micro plastic driving changes in the soil microbes and lettuce growth under the influence of heavy metals contaminated soil
Researchers studied how microplastics interact with heavy metals in contaminated soil and their combined effects on lettuce growth and soil bacteria. Different types of microplastics altered soil chemistry and changed which microbes thrived, sometimes making heavy metals more available to plants. The study suggests that microplastic-contaminated agricultural soil could affect both the safety and nutritional quality of leafy vegetables that people eat.
Effect of polyethylene particles on dibutyl phthalate toxicity in lettuce (Lactuca sativa L.).
Polyethylene microplastic fragments in soil reduced the uptake of the plasticizer chemical dibutyl phthalate (DBP) into lettuce roots but worsened its inhibitory effects on root growth. The complex interactions between microplastics and co-occurring chemical contaminants like phthalates can alter toxicity in unexpected ways, affecting both plant growth and the safety of food crops.
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.
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.
Effects of polyester microplastics and naproxen on lettuce growth and development and soil abiotic factors
This study tested the effects of polyester microplastics and the anti-inflammatory drug naproxen -- alone and in combination -- on lettuce growth and soil properties. Polyester microplastics altered soil abiotic factors and affected lettuce development, while combined exposure with naproxen produced interactive effects on plant metrics, raising concerns about the joint risks of plastic and pharmaceutical co-contamination in agricultural soils.
Impact of different microplastics polymers and albendazole and pyraclostrobin mix on arugula (Eruca vesicaria) physiology and growth
Researchers exposed arugula plants to conventional (LDPE) and biodegradable (PBAT) microplastics combined with a pesticide-antiparasitic mixture, and found that only the conventional plastic significantly amplified the chemicals' toxicity, reducing plant growth more than either pollutant alone. This shows that conventional microplastics can act as carriers that worsen the effects of agricultural chemicals in soil.
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.
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.
Single low-density polyethylene microplastics stress and drought co-exposure effects on lettuce (Lactuca sativa) physiology, growth, and root development
Lettuce was grown in soil contaminated with LDPE microplastics at 0.75% and 1.5% w/w, alone or combined with drought stress (20% plant available water). Drought stress had larger negative effects on growth than MPs alone, but combined exposure produced additive or synergistic reductions in biomass and physiological function.
[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.

Researchers tested how two common biodegradable microplastics affect lettuce growth and the microbial communities around its roots. At higher concentrations, both types of biodegradable plastics inhibited lettuce growth and significantly disrupted the balance of beneficial soil microbes and plant metabolic processes. The findings suggest that even plastics marketed as biodegradable can negatively impact soil health and crop development when present in sufficient quantities.
Environmental efficacy of polyethylene microplastics: Enhancing the solidification of CuO nanoparticles and reducing the physiological toxicity to peanuts
Researchers examined how polyethylene microplastics interact with copper oxide nanoparticles in soil and their combined effects on peanut plant growth. They found that while polyethylene alone had minimal impact, it reduced the dissolution and absorption of toxic copper oxide nanoparticles, effectively lessening their harmful effects on peanut biomass. The study suggests that microplastics may sometimes act as a moderating influence on the toxicity of co-occurring metal nanoparticle pollutants in agricultural settings.
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.
