ClearEffects 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.
The Combined Toxic Effects of Polystyrene Microplastics and Arsenate on Lettuce Under Hydroponic Conditions
Researchers found that polystyrene microplastics and arsenic together caused more harm to lettuce than either pollutant alone, reducing root growth and chlorophyll content by up to 71%. The arsenic actually helped microplastics penetrate deeper into plant tissue, and the combination made the soil around roots more acidic. This study is important because it shows that microplastics in farm soil can worsen the effects of other contaminants on food crops.
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.
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.
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.
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.
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.
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.
Microplastic mediated arsenic toxicity involves differential bioavailability of arsenic and modulated uptake in rice (Oryza sativa L.)
Researchers examined how polyethylene and polylactic acid microplastics interact with arsenic contamination in rice paddies. They found that at low arsenic levels, microplastics actually reduced arsenic uptake by rice plants, but at high arsenic concentrations the combination produced synergistic toxic effects. The study reveals that the interaction between microplastics and heavy metals in agricultural soils is more complex than previously thought and depends heavily on contaminant concentration levels.
Mechanistic insight into interactive effect of microplastics and arsenic on growth of rice (Oryza sativa L.) and soil health indicators
Researchers tested how different types of microplastics interact with arsenic contamination in rice paddy soil, finding that biodegradable PLA microplastics actually increased arsenic uptake by rice plants by up to 39%. In contrast, conventional polyethylene microplastics slightly reduced arsenic absorption. This is an important finding because as agriculture shifts toward biodegradable plastics, they may inadvertently increase the transfer of toxic heavy metals from soil into 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.
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.
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.
Microplastics change the safe production ability of arsenic-stressed rice (Oryza sativa L.) by regulating the antioxidant capacity, arsenic absorption, and distribution in rice
Researchers studied how polyethylene and biodegradable polylactic acid microplastics interact with arsenic contamination to affect rice growth and food safety. They found that the type of microplastic influenced how arsenic accumulated in different parts of the rice plant, with some combinations increasing arsenic levels in the edible grain. The findings raise concerns about microplastic contamination in agricultural soils altering how toxic metals are taken up by food crops.
Impact of Co-Contaminants (Microplastics and Others) on Heavy Metal/Metalloid Toxicity and Accumulation in Plants
This review examines how microplastics act as co-contaminants alongside heavy metals and metalloids in agricultural soils, influencing their toxicity and uptake by plants. Researchers found that the presence of microplastics can alter how metals like cadmium, arsenic, and lead accumulate in plant tissues, with implications for crop safety and agricultural productivity.
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.
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.
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.
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.
