ClearResponses 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.
Combined toxic effects of enrofloxacin and microplastics on submerged plants and epiphytic biofilms in high nitrogen and phosphorus waters
Researchers studied the combined effects of the antibiotic enrofloxacin and microplastics on the submerged plant Myriophyllum verticillatum in nutrient-rich water. The study found that while microplastics alone had little effect, their combination with enrofloxacin produced synergistic toxic effects, reducing the plant's ability to absorb nitrogen and phosphorus and decreasing photosynthetic pigment content.

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.
Single and combined toxicity effects of microplastics and perfluorooctanoic acid on submerged macrophytes and biofilms
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.

Researchers investigated long-term combined effects of ciprofloxacin and microplastics on the polychaete Hediste diversicolor, finding that co-exposure produced distinct behavioral and biochemical responses compared to individual contaminant exposure in estuarine organisms.
Nanoplastics and their combined effects with sulphamethoxazole on the free-floating aquatic plant Lemna major
Researchers examined the combined effects of nanoplastics and the antibiotic sulphamethoxazole on free-floating algae, assessing whether nanoplastics alter antibiotic toxicity. The co-exposure produced greater inhibitory effects on algal growth than either substance alone.
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.
Aged microplastics enhance their interaction with ciprofloxacin and joint toxicity on Escherichia coli
Researchers found that aged microplastics showed enhanced adsorption of the antibiotic ciprofloxacin compared to pristine particles, and that their combined exposure produced greater toxicity to E. coli at the molecular level than either pollutant alone.

The combined contaminant-carrying microplastics caused greater toxicity to primary producers than either MPs or antibiotics alone.
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.
Effects of heavy metals on the adsorption of ciprofloxacin on polyethylene microplastics: Mechanism and toxicity evaluation
Researchers studied how heavy metals in water affect the ability of polyethylene microplastics to absorb the antibiotic ciprofloxacin. They found that heavy metals competed with the antibiotic for binding sites on the microplastic surface, changing how much of each pollutant the plastic could carry. This is important because it shows microplastics in real-world environments may transport different combinations of pollutants, potentially delivering both antibiotics and heavy metals into the food chain.

This review examines how microplastics and pharmaceutical or personal care product residues interact when they co-occur in aquatic environments and affect algae. Researchers found that the combined effects can be either antagonistic or synergistic depending on factors like microplastic size, charge, and the type of chemical involved. The study identifies the type of pharmaceutical compound and the species of algae as the most important factors determining whether these pollutant combinations cause greater or lesser harm.
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.

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.
