ClearThe Effects of Polystyrene Microplastics and Copper Ion Co-Contamination on the Growth of Rice Seedlings
Researchers studied how polystyrene microplastics and copper ions interact when both are present in the water supply of rice seedlings. They found that microplastics actually reduced copper toxicity by absorbing the metal ions, but both pollutants weakened the plant's antioxidant defenses. The study suggests that microplastics and heavy metals interact in complex ways in agricultural systems, with implications for crop health and food 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.
Understanding the Role of Low-Dose Polystyrene Microplastic in Copper Toxicity to Rice Seed (Oryza sativa L.)
This study explored how polystyrene microplastics interact with copper toxicity in rice seeds. Researchers found that microplastics actually reduced copper's harmful effects by physically accumulating on seed coats and blocking copper absorption, lowering the amount of copper taken up by seedlings by about 34%. The findings highlight how microplastics can alter the way other environmental contaminants affect plants.

Effects of Microplastics on the Mineral Elements Absorption and Accumulation in Hydroponic Rice Seedlings (Oryza sativa L.)
Researchers exposed rice seedlings to different concentrations of polyethylene microplastics in hydroponic conditions and measured the effects on mineral nutrient absorption. They found that while microplastics did not affect shoot growth, they significantly altered the uptake and distribution of essential mineral elements in the plants. The study suggests that microplastic contamination in agricultural settings could disrupt crop nutrition even without visible growth impacts.
Effects of microplastics on growth and metabolism of rice (Oryza sativa L.)

Polystyrene microplastics enhanced the toxicity of cadmium to rice seedlings: Evidence from rice growth, physiology, and element metabolism
Polystyrene microplastics combined with cadmium -- a toxic heavy metal -- caused more damage to rice seedlings than either pollutant alone, reducing growth and disrupting the balance of essential nutrients. At higher concentrations, the microplastics significantly increased how much cadmium the plants absorbed into their above-ground parts. This matters for human health because rice is a staple food for billions of people, and microplastic-contaminated farmland could lead to higher heavy metal levels in the food supply.
The effect of microplastic contaminated compost on the growth of rice seedlings
Researchers found that adding PET microplastics to compost significantly harmed rice seedling growth, reducing root length by 38%, plant height by 25%, and chlorophyll content by up to 55%. The microplastics appeared to interfere with nutrient uptake and photosynthesis. This is concerning because compost used in agriculture is often contaminated with plastic waste, which could reduce crop yields and potentially affect food quality.
Combined Effects of Polyethylene and Bordeaux Mixture on the Soil–Plant System: Phytotoxicity, Copper Accumulation and Changes in Microbial Abundance
Researchers studied the combined effects of polyethylene microplastics and Bordeaux mixture (a copper-based fungicide) on lettuce growth and soil microbes over 28 days. They found that copper treatments affected root and shoot growth, while microplastics alone showed limited effects and may have reduced copper bioavailability. The study suggests that the interaction between agricultural plastics and agrochemical residues creates complex, sometimes offsetting effects on soil-plant systems.
Investigating the Impact of Microplastics Type of Polyethylene, Polypropylene, and Polystyrene on Seed Germination and Early Growth of Rice Plants
Researchers investigated how three common types of microplastics, polyethylene, polypropylene, and polystyrene, affect rice seed germination and early seedling growth. They found that microplastic exposure altered root development and shoot growth, with the effects varying by polymer type. The study raises concerns about how microplastic-contaminated agricultural soils could affect staple crop establishment and food production.

Results showed interactions between microplastics and the antibiotic that affected seedling growth and uptake of the contaminants.
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.

Assessing the interactive effects of microplastics and acid rain on cadmium toxicity in rice seedlings: Insights from physiological and transcriptomic analyses
Researchers studied how the combination of microplastics, acid rain, and cadmium affects rice seedling growth. They found that at high cadmium concentrations, the presence of microplastics and acid rain actually reduced cadmium's toxic effects by lowering how much of the metal accumulated in the plants. The study provides nuanced evidence that interactions between multiple environmental pollutants can sometimes produce unexpected outcomes, which matters for understanding food safety in contaminated agricultural areas.
Effect of High-Density Polyethylene, Polyvinyl Chloride and Low-Density Polyethylene Microplastics on Seeding of Paddy
This study tested how three common types of plastic microparticles affect rice seedling growth, finding that they can interfere with early plant development. The results matter for food safety because rice is a staple crop for billions of people, and microplastic contamination in agricultural soil could affect crop yields and potentially introduce plastic particles into the food supply.

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.
[Effects of Combined Pollution of Microplastics and Lead on Maize Seed Germination and Growth].
Researchers grew maize seeds in water spiked with lead and three common microplastics (polyethylene, polypropylene, and PVC) to test their combined effects on germination and early growth. All three plastics individually inhibited germination to varying degrees, but when combined with lead the effects were generally antagonistic — meaning the mixture was less toxic than each pollutant alone. These findings are important for understanding real-world soil contamination, where microplastics and heavy metals often co-occur in agricultural environments.

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.
