ClearEffects 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.
Co-exposure of di(2-ethylhexyl) phthalate (DEHP) decreased the submicron plastic stress in soil–plant system
This study investigated how submicron plastic particles and the plasticizer DEHP interact in soil-lettuce systems, unexpectedly finding that DEHP reduced plastic uptake into lettuce roots and alleviated—rather than exacerbated—the phytotoxic effects of the plastics.
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.
Effect of polystyrene on di-butyl phthalate (DBP) bioavailability and DBP-induced phytotoxicity in lettuce
Researchers investigated how polystyrene microplastics of different sizes affect the bioavailability of the plasticizer di-butyl phthalate and its toxicity to lettuce plants. They found that smaller nanoscale polystyrene particles increased DBP uptake by the plants, while larger particles reduced it by adsorbing the chemical. The study demonstrates that microplastics can act as carriers for harmful chemicals in agricultural soils, with particle size determining whether they amplify or reduce pollutant exposure to crops.
Co-exposure of di(2-ethylhexyl) phthalate (DEHP) decreased the submicron plastic stress in soil–plant system
Researchers exposed lettuce plants to submicron plastic particles combined with DEHP (a common plasticizer found in agricultural films), finding that DEHP surprisingly reduced how much plastic the plants absorbed and lowered oxidative stress markers. This unexpected result suggests that when plastics and their chemical additives are present together in soil — as they typically are — they can counteract each other's harmful effects rather than amplifying them.
Microplastic pollution in agriculture: How exposure pathway (Seed, Leaf, Root) dictates phytotoxicity in lettuce (Lactuca sativa L.)
This study compared the phytotoxicity of polyethylene microplastics applied to lettuce via seed, leaf, and root exposure pathways, finding that root exposure caused the greatest growth inhibition and oxidative stress. The route of MP exposure significantly influenced the type and severity of toxic effects on crops.
Polystyrene particles combined with di-butyl phthalate cause significant decrease in photosynthesis and red lettuce quality
Researchers grew red lettuce hydroponically with polystyrene microplastics and dibutyl phthalate, finding that microplastics reduced the bioavailability of the plasticizer while simultaneously decreasing photosynthetic efficiency and chlorophyll content.
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.
The short-term effect of microplastics in lettuce involves size- and dose-dependent coordinate shaping of root metabolome, exudation profile and rhizomicrobiome
Researchers exposed lettuce plants to polyethylene plastic particles of four different sizes and concentrations, finding that the plastics altered root chemistry, changed what the roots released into the soil, and shifted the bacteria living around them. The effects depended strongly on particle size, with smaller particles causing different metabolic changes than larger ones. This study shows that microplastics in farm soil can change the biology of food crops from the roots up, potentially affecting both crop health and nutritional quality.
Effects of Soil Microplastics on Plant Growth and Soil Health
A greenhouse experiment found that polyethylene and polypropylene microplastics at increasing concentrations reduced lettuce biomass, altered soil microbial activity, and changed soil structure and water retention, with effects more pronounced at higher MP concentrations.
Uptake, Distribution, and Impact of Micro- and Nano-Plastics in Horticultural Systems Using Lettuce (Lactuca sativa) as a Model Crop
Researchers studied how micro- and nanoplastics are taken up and distributed in lettuce grown in horticultural systems, finding that nanopolystyrene exposures significantly inhibited leaf and root development in a concentration-dependent manner. They optimized extraction methods for quantifying microplastics in soil and developed a synthesis procedure for nanoplastic test particles. The study demonstrates that plastic fragments from horticultural materials can accumulate in soil and affect crop growth, raising concerns about food safety.
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 microplastics on dry matter content in Lactuca sativa L.
This study tested the effects of microplastic particles on dry matter content in lettuce plants, finding that microplastic exposure affected plant biomass production. As agricultural soils accumulate microplastics, their effects on crop yield and nutritional quality become important food safety concerns.
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.
Polyethylene microplastic modulates lettuce root exudates and induces oxidative damage under prolonged hydroponic exposure
Researchers grew lettuce in water containing polyethylene microplastics for 28 days and found that the plastics changed the chemical signals the roots released and caused oxidative damage in the leaves. While the plants looked mostly normal on the outside, the microplastics altered the root chemistry in ways that could affect nutrient uptake and plant defense. This is relevant to human health because lettuce is widely consumed and may be grown in microplastic-contaminated water or soil.
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.
Physiological responses of lettuce (Lactuca sativa L.) to microplastic pollution
PVC microplastics of two different size ranges had contrasting effects on lettuce roots, with smaller particles stimulating root growth and larger particles having no effect, and smaller particles also reduced photosynthetic efficiency at moderate concentrations. The study suggests that microplastic size is a key variable determining whether effects on crops are stimulatory or inhibitory.
Effect of different types and shapes of microplastics on the growth of lettuce
Researchers tested how different types and shapes of microplastics in soil affect lettuce growth in pot experiments. They found that polyvinyl chloride fragments had the most negative impact on lettuce weight and root development, while low-density polyethylene fibers showed less effect. The study indicates that the type and shape of microplastic contamination in agricultural soils matters significantly for crop health outcomes.
Influence of polyethylene microplastics on Brassica rapa: Toxicity mechanism investigation
Researchers exposed the fast-growing plant Brassica rapa (related to turnip and cabbage) to polyethylene microplastics that had been degraded by sunlight, finding that the plastics stunted plant growth by up to 51% and triggered cellular stress responses. Genetic analysis revealed the microplastics disrupted the plant's immune and growth pathways, providing insight into how plastic pollution in agricultural soil could affect food crops.
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.
