ClearSynergistic 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.
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.
Microplastic particles increase arsenic toxicity to rice seedlings
Researchers studied how polystyrene and polytetrafluoroethylene microplastics interact with arsenic to affect rice seedling growth. They found that microplastics alone reduced plant biomass and inhibited photosynthesis, while the combination with arsenic at higher concentrations amplified the toxic effects on root activity and cell membranes. The study reveals that microplastic contamination in agricultural settings may worsen the impact of other pollutants on food crops.
The combined toxicity of polystyrene microplastic and arsenate: From the view of biochemical process in wheat seedlings (Triticum aestivum L.)
Researchers found that when wheat seedlings were exposed to both arsenic and polystyrene microplastics together, the microplastics reduced arsenic uptake in roots but dramatically increased arsenic transport to the above-ground parts of the plant — by up to 1,000%. This combined exposure caused more oxidative stress and damage to the plants' photosynthetic systems than arsenic alone. The findings suggest that microplastics in contaminated soil could increase how much toxic metal ends up in the edible parts of crops.
Micro-nanoscale polystyrene co-exposure impacts the uptake and translocation of arsenic and boscalid by lettuce (Lactuca sativa)
Researchers found that nanoscale polystyrene particles dramatically increase arsenic translocation from roots to edible shoots of lettuce — up to threefold — while also entering root cells and migrating to leaves, demonstrating that microplastic co-exposure can substantially amplify the accumulation of other environmental contaminants in food crops.
Effects of naturally aged microplastics on the distribution and bioavailability of arsenic in soil aggregates and its accumulation in lettuce
Scientists studied how weathered microplastics interact with arsenic, a toxic element, in soil where lettuce is grown. At low to moderate arsenic levels, the microplastics actually helped the lettuce grow better and reduced arsenic uptake. However, at high arsenic concentrations, microplastics made the toxicity worse, reducing leaf quality and nutrition. This shows that the health impact of microplastics in farming depends heavily on what other contaminants are present in the soil.
Effects of microplastics and arsenic on plants: Interactions, toxicity and environmental implications
This review examines how microplastics and arsenic interact in soil and their combined effects on plant health. When both pollutants are present together, they can have amplified toxic effects on plants, affecting growth, nutrient uptake, and stress responses. Since plants absorb these contaminants from soil, the interaction between microplastics and arsenic could increase human exposure to both pollutants through food crops.
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.
Polyethylene Nanoplastics Intensify Arsenic Toxicity in Lettuce by Altering Arsenic Accumulation and Stress Pathways
Researchers grew lettuce in arsenic-contaminated farmland soil amended with polyethylene nanoplastics and found that nanoplastic exposure increased arsenic accumulation in edible leaves by 35–39%, reduced plant biomass by up to 30%, and disrupted antioxidant metabolism, highlighting compounded food safety risks in contaminated agricultural soils.
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.
[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.
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.
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 microplastics and arsenic on nutrients and microorganisms in rice rhizosphere soil
Researchers investigated how polystyrene and polytetrafluoroethylene microplastics interact with arsenic contamination in rice rhizosphere soil. The study found that microplastics reduced arsenic bioavailability and altered microbial communities, while both pollutants together inhibited key soil enzyme activities and reduced available nitrogen and phosphorus, suggesting combined microplastic-arsenic pollution can impair nutrient cycling and crop growth.
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.
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.
Response of garlic (Allium sativum L.) to the combined toxicity of microplastics and arsenic
Researchers studied how polystyrene microplastics and arsenic interact when both are present in soil where garlic is growing. They found that nanoscale plastic particles can enter garlic through the roots and accumulate in plant tissues, and that higher microplastic concentrations actually increased arsenic transport into the edible bulb. The study highlights potential food safety concerns when crops are grown in soil contaminated with both microplastics and heavy metals.
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.
Single and joint toxicity of polymethyl methacrylate microplastics and As (V) on rapeseed (Brassia campestris L.)
Researchers evaluated the individual and combined toxicity of polymethyl methacrylate microplastics and arsenic on rapeseed plants. They found that nanoscale plastic particles were more toxic than microscale ones, and the combination of nanoplastics with arsenic produced synergistic harmful effects on germination, growth, and arsenic accumulation in plant tissues. The study raises concerns about the combined impact of microplastics and heavy metals on crop safety in contaminated farmland.
Uptake of microplastics by carrots in presence of As (III): Combined toxic effects
Researchers found that polystyrene microplastics as small as 0.2 micrometers can enter carrot roots and travel up to the leaves, and the presence of arsenic in water made the problem worse by allowing even larger particles to penetrate plant cells. The combination of microplastics and arsenic caused oxidative damage and reduced carrot quality, including loss of crispness. This study shows that root vegetables grown in contaminated water could absorb microplastics directly into the parts that people 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.
The joint toxicity of polyethylene microplastic and phenanthrene to wheat seedlings
Researchers studied the individual and combined effects of polyethylene microplastics and the pollutant phenanthrene on wheat seedlings grown in soil. They found that microplastics alone caused dose-dependent reductions in plant growth and damaged the photosynthetic system, while the combination with phenanthrene worsened the damage. The study suggests that the co-occurrence of microplastics and organic pollutants in agricultural soils may create compounding negative effects on crop growth.
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.
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.
