ClearMicroplastics and co-pollutant with ciprofloxacin affect interactions between free-floating macrophytes
Researchers found that polyethylene microplastics and ciprofloxacin co-pollutants altered competitive interactions between free-floating macrophytes, with combined exposure affecting plant growth and physiological responses differently than individual pollutant exposure.
Responses of submerged macrophytes to different particle size microplastics and tetracycline co-pollutants at the community and population level
Researchers set up outdoor experimental ponds to study how microplastics of different sizes combined with the antibiotic tetracycline affect communities of underwater aquatic plants. Smaller microplastics caused more harm to plant diversity and growth, and the combined exposure with antibiotics created worse effects than either pollutant alone. The study suggests that microplastic pollution could amplify the damage antibiotics cause to freshwater plant ecosystems.

When antibiotics encounter microplastics in aquatic environments: Interaction, combined toxicity, and risk assessments
A meta-analysis of the combined toxicity of antibiotics and microplastics in aquatic environments found significant adverse effects on algae but limited apparent effects on fish and daphnia. Microplastics alter antibiotic environmental behavior through adsorption and co-transport, and their coexistence is widespread across global aquatic study sites, though standardized risk assessment methods for combined exposure remain lacking.
Unraveling the toxic mechanisms of microplastics in aquatic ecosystem: A case study on Vallisneria natans and Myriophyllum verticillatum
Researchers exposed two submerged aquatic plant species (Vallisneria natans and Myriophyllum verticillatum) to PVC, polystyrene, and polyethylene microplastics at three concentrations, finding that all three types significantly inhibited photosynthesis and growth and triggered oxidative stress, with effects varying by plastic type and plant species.

Researchers tested the combined effects of four common microplastic types and PFOA (a forever chemical) on aquatic plants and their associated biofilms. The pollutants together caused more damage to plant growth, photosynthesis, and microbial communities than either pollutant alone. Since microplastics and PFOA frequently co-occur in the environment, their combined toxic effects on aquatic ecosystems could have downstream consequences for water quality and human exposure.
Single and combined toxicity of polystyrene nanoplastics and arsenic on submerged plant Myriophyllum verticillatum L.
Researchers investigated the combined toxicity of polystyrene nanoplastics and arsenic on the submerged aquatic plant Myriophyllum verticillatum. They found that nanoplastics reduced arsenic accumulation in the plant by 17 to 67 percent, and that the interaction between the two contaminants was dose-dependent, with nanoplastics alleviating arsenic toxicity at low doses but worsening it at higher concentrations. The study suggests that co-contamination of nanoplastics and heavy metals in freshwater environments may have complex ecological effects.
Higher toxicity induced by co-exposure of polystyrene microplastics and chloramphenicol to Microcystis aeruginosa: Experimental study and molecular dynamics simulation
Researchers studied what happens when the antibiotic chloramphenicol and polystyrene microplastics are present together in water containing blue-green algae. The study found that the combined exposure was more toxic to the algae than either pollutant alone, disrupting photosynthesis and gene expression. The findings suggest that microplastics and antibiotics may interact in ways that amplify their harmful effects on aquatic ecosystems.
Interactive toxicity effects of metronidazole, diclofenac, ibuprofen, and differently functionalized nanoplastics on marine algae Chlorella sp.
Researchers examined the combined toxicity of common pharmaceutical drugs and nanoplastics with different surface coatings on marine algae. They found that the interaction between drugs and nanoplastics produced effects ranging from additive to synergistic, depending on the specific combination, with amine-coated nanoplastics generally causing more harm. The study highlights that real-world mixtures of pharmaceutical and plastic pollutants in oceans may pose greater risks to marine life than either contaminant alone.
Rainbow trout (Oncorhynchus mykiss) physiological response to microplastics and enrofloxacin: Novel pathways to investigate microplastic synergistic effects on pharmaceuticals
Scientists studied how microplastics interact with the antibiotic enrofloxacin in rainbow trout and found that the combination increased toxicity beyond what either pollutant caused alone. The microplastics appeared to change how the antibiotic was absorbed and processed in the fish, leading to greater liver damage and immune system disruption. Since fish are exposed to both pollutants in real waterways, this synergistic toxicity could affect seafood safety and the health of people who consume contaminated fish.
Unraveling individual and combined toxicity of nano/microplastics and ciprofloxacin to Synechocystis sp. at the cellular and molecular levels
Researchers studied the individual and combined toxic effects of nano- and microplastics with the antibiotic ciprofloxacin on a freshwater cyanobacterium. They found that while each pollutant caused harm on its own, the antibiotic actually showed an antagonistic interaction with the plastic particles, reducing some of their combined toxicity. The study provides important insights into how microplastics and pharmaceutical pollutants interact in aquatic environments, which may complicate pollution risk assessments.
Mechanism of the Synergistic Toxicity of Ampicillin and Cefazoline on Selenastrum capricornutum
Researchers studied how two common antibiotics, ampicillin and cefazolin, work together to harm freshwater algae, finding that their combined effect is worse than either antibiotic alone. The antibiotics disrupted the algae's growth, metabolism, and photosynthesis at the genetic level. While focused on antibiotic pollution rather than microplastics, the study is relevant because microplastics can carry antibiotics through waterways, potentially amplifying these toxic effects on aquatic ecosystems.
Influence of microplastics on the toxicity of the pharmaceuticals procainamide and doxycycline on the marine microalgae Tetraselmis chuii
Researchers investigated whether the presence of microplastics influences the toxicity of two pharmaceuticals, procainamide and doxycycline, on the marine microalga Tetraselmis chuii. They found that microplastics alone had limited effects, but when combined with pharmaceuticals, the mixture interactions varied depending on the drug and the measured endpoint. The study suggests that the co-occurrence of microplastics and pharmaceutical pollutants in marine environments may produce unpredictable combined effects on primary producers.
Single and combined effects of polystyrene nanoplastics and Cd on submerged plants Ceratophyllum demersum L.

They found that nanoplastics worsened cadmium's harmful effects on plant growth, photosynthesis, and cellular health, reducing growth rates by over 35%. The study suggests that when nanoplastics and heavy metals co-occur in water, their combined impact on aquatic plants may be more severe than either pollutant alone.
Ecotoxicological Effects of Microplastics Combined With Antibiotics in the Aquatic Environment: Recent Developments and Prospects
This review examines how microplastics and antibiotics interact in water environments, finding that microplastics can absorb antibiotics onto their surfaces and carry them over long distances. When aquatic organisms encounter these antibiotic-laden microplastics, the combined toxicity can be worse than either pollutant alone. Microplastics also promote the spread of antibiotic resistance genes, which is a growing public health concern.
Cascading effects of microplastic-pollutant co-exposure in coastal wetland soil-plant-microbe systems: Mitigation potential through nutrient management
This study examined how the co-exposure of microplastics with two common pollutants—a flame retardant (TCPP) and an antibiotic (oxytetracycline)—affects coastal wetland soil-plant-microbe systems. The combined exposures produced cascading harmful effects on plant health and microbial communities that exceeded single-contaminant impacts, and nutrient management partially offset the damage.

The combination caused greater toxicity than either contaminant alone, particularly at chronic exposure durations, indicating synergistic effects relevant to agricultural runoff contamination.
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.
