ClearMicro and nanoplastics as emerging stressors influencing plant metabolism and nutrient dynamics
This review of existing research shows that tiny plastic particles in farm soil can get inside plants and change how they grow and absorb nutrients. When plants take up these microplastics, it could affect the nutritional quality of the fruits and vegetables we eat, potentially impacting our food safety. However, scientists still need more long-term studies to fully understand how serious this threat is to our food supply and health.
Effects of microplastics on selected physical properties of agricultural soils and on the response of the selected terrestrial isopod
Scientists found that tiny plastic pieces from agricultural films change how soil holds and releases water, with some types increasing available water for plants by about 5%. These microplastics also affect soil creatures that help keep ecosystems healthy. This matters because these plastic particles could be changing how our food is grown and may eventually end up in the crops we eat.
Microplastics in Mediterranean Agricultural Soils: Effects on Soil Properties, Metal Accumulation in Plants, and Implications for Sustainable Agroecosystems
Scientists found that tiny plastic particles in soil make it easier for toxic metals like lead and zinc to move into plants we might eat. Even small amounts of microplastics changed how metals behave in the soil, with some types of plastic causing up to 20% more metal absorption in plants. This matters because these contaminated plants could end up in our food supply, potentially increasing our exposure to harmful metals.
Aged polyethylene microplastics modulate herbicide and antibiotic bioavailability and plant responses: a case study with glyphosate and tetracycline
Researchers generated experimental data on how aged polyethylene microplastics affect the behavior of the herbicide glyphosate and the antibiotic tetracycline in hydroponic plant growth systems. The dataset includes measurements of pollutant sorption, plant photosynthetic pigments, and antioxidant enzyme activity in rapeseed plants exposed to various combinations of microplastics and chemicals. The study suggests that microplastics can modulate how other environmental contaminants interact with plants.
Tiny pollutants, big consequences: investigating the influence of nano- and microplastics on soil properties and plant health with mitigation strategies
Researchers reviewed the impact of nanoplastics and microplastics on soil properties and plant health, examining absorption and translocation mechanisms in plants. The study suggests that plastic particles alter soil structure and microbial communities, impair plant growth and nutrient uptake, and proposes mitigation strategies to address these emerging threats to agricultural ecosystems.
Does Microplastic Contamination in Agricultural Soils Decrease the Efficiency of Herbicides for Weed Control?
Researchers investigated how microplastic contamination in agricultural soils affects herbicide performance. They found that microplastics absorb herbicides onto their surfaces, reducing the chemicals' availability for weed control and slowing their degradation by inhibiting soil microbial activity. The study suggests that microplastic pollution in farmland may undermine herbicide efficacy while increasing the persistence of these chemicals in the environment.
Microplastics affect soil-plant system: Implications for rhizosphere biology and fitness of sage (Salvia officinalis L.)
Researchers found that polyethylene microplastics from agricultural plastic film disrupted the soil ecosystem and harmed sage plants in a controlled experiment. The microplastics altered the communities of bacteria and fungi in the soil, reduced the plants' chlorophyll levels, and increased oxidative stress. This study matters because it shows microplastics from common farm materials can degrade soil health and potentially affect the quality of crops and herbs grown for human consumption.
Mechanisms of microplastic accumulation in the root zones of agricultural soils
Scientists found that tiny plastic pieces from farm materials like mulch films get stuck in soil and don't wash away easily, causing them to build up over time in areas where food is grown. This matters because these microplastics can potentially enter our food supply through crops that absorb them from contaminated soil. The research shows it's very difficult to remove these plastic particles once they're in farmland, suggesting we need better prevention methods to protect our food system.
Particulate plastics-plant interaction in soil and its implications: A review
This review examines how micro- and nanoplastics in soil interact with plants, including uptake through roots, accumulation in plant tissues, and effects on growth, nutrient absorption, and soil microbial communities. The study highlights that these plastic particles can alter soil structure and chemistry in ways that affect crop development, raising concerns about food safety and agricultural productivity.
The role of microplastic pollution in the modification of the physicochemical properties of arable soil and uptake of potential toxic elements by plants
Researchers conducted a series of studies analyzing how microplastic pollution modifies the physicochemical properties of arable soil and affects the uptake of potentially toxic heavy metals by plants, beginning with a comprehensive literature review of microplastic interactions with plant physiology, metals, pesticides, and pathogens.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
Effects of microplastics on the environmental behaviors of the herbicide atrazine in soil: Dissipation, adsorption, and bioconcentration
Researchers examined how the presence of microplastics in soil affects the behavior of the herbicide atrazine, including how quickly it breaks down and how much is absorbed by plants. They found that microplastics reduced the herbicide's half-life in soil, increased its adsorption to soil particles, and significantly boosted its uptake into plant tissues. The study suggests that microplastic contamination in agricultural soils could change how pesticides behave, potentially increasing crop contamination.
How do nanoplastics hijack crop physiology: A review of uptake pathways and agricultural sustainability implications
This research review summarizes how tiny plastic particles called nanoplastics can get inside crop plants through their roots and leaves, potentially harming how plants grow and produce food. These ultra-small plastic pieces interfere with how plants absorb nutrients and respond to stress, which could threaten our food supply. Since we eat these crops, understanding how nanoplastics affect plant health is important for protecting both agriculture and human health.
Synergistic modulation of Lead (II) bioavailability by polyethylene terephthalate microplastics and insights into assimilation kinetics in Canna indica
Scientists found that tiny plastic particles (microplastics) in soil can make plants absorb up to 250% more lead, a toxic heavy metal that's harmful to humans. This happens because the plastic pieces act like a delivery system, carrying more lead into plants that we might eventually eat. This research suggests that areas with plastic pollution in the soil could pose greater health risks than previously thought, especially for crops grown in contaminated areas.
Effects of Microplastics on Bioavailability, Persistence and Toxicity of Plant Pesticides: An Agricultural Perspective
This review examines how microplastics in soil interact with pesticides, generally reducing pesticide effectiveness by absorbing the chemicals onto their surfaces. While this lowers the immediate toxicity of pesticides, it also makes them last longer in the environment and may reduce pest control in agriculture, potentially affecting food production and the long-term safety of the food supply.
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.
Polyethylene Microplastics Inhibit Peanut Nodulation via Metabolic and Transcriptional Pathways
Scientists found that tiny plastic pieces from agricultural plastic films prevent peanut plants from forming healthy partnerships with beneficial soil bacteria that help them grow. These microplastics disrupt the plant's natural processes and block the formation of root nodules, which are essential for peanuts to get nitrogen from soil bacteria. This matters because it shows how plastic pollution in farmland could reduce crop yields and food production, potentially affecting our food supply.
From the rhizosphere to plant fitness: Implications of microplastics soil pollution
Researchers exposed strawberry plants to low-density polyethylene microplastics in soil and found significant harm, including reduced chlorophyll levels, altered nutrient uptake, and increased stress responses. The microplastics also shifted the soil microbiome toward potentially harmful fungi and bacteria. These findings show that microplastics in agricultural soil can damage crop health and change the microbial community that plants depend on.
Do Microplastics in Soil Influence the Bioavailability of Sulfamethoxazole to Plants?
Researchers investigated how three types of microplastics affect the availability and toxicity of the antibiotic sulfamethoxazole in soil using sorghum plants. They found that low concentrations of the antibiotic actually stimulated plant growth, while higher concentrations inhibited it, and the presence of microplastics generally reduced the antibiotic's toxicity. The study highlights that microplastics in agricultural soils can alter how pharmaceutical contaminants behave, with polystyrene having the strongest effect on drug availability.
Size and concentration-dependent effects of polyethylene microplastics on soil chemistry in a microcosm study
Researchers tested how polyethylene microplastics of different sizes and concentrations affect soil chemistry in a controlled lab setting. They found that the smallest microplastic particles reduced the soil's ability to hold nutrients by nearly 13% and altered dissolved organic matter, while also leaching phthalate chemicals into the soil. The study suggests that as microplastics accumulate in agricultural soils, they could impair important soil functions related to nutrient retention and pollutant movement.
