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.

Unraveling the combined impacts of pristine and aged polyethylene microplastics and the ciprofloxacin antibiotic on sediment microbial communities and ecological functions
Researchers examined how polyethylene microplastics — both fresh and environmentally weathered — interact with the antibiotic ciprofloxacin to affect the microbial communities living in aquatic sediments. They found that microplastics, especially in combination with the antibiotic, disrupted microbial community structure and simplified the ecological networks that microbes rely on for stable functioning. This is concerning because healthy sediment microbe communities underpin nutrient cycling and ecosystem health, and their disruption by combined plastic-antibiotic pollution could have cascading effects.
Ecological impacts of polylactic acid and polylactic acid-polyethylene microplastics on freshwater ecosystems: Insights from a water–Vallisneria natans–sediment system
Researchers tested the effects of biodegradable PLA and PLA-polyethylene blend microplastics on a freshwater ecosystem containing aquatic plants and sediment. Both types of microplastics altered water chemistry, reduced plant growth, increased oxidative stress, and shifted the microbial communities in both water and sediment. The study demonstrates that even biodegradable plastic alternatives can disrupt freshwater ecosystems in meaningful ways.
Nanoplastics and their combined effects with sulphamethoxazole on the free-floating aquatic plant Lemna major
Researchers studied the combined effects of polystyrene nanoplastics and the antibiotic sulfamethoxazole on free-floating freshwater organisms, examining how co-exposure to these two pollutants interacts compared to individual exposures. Nanoplastics altered the bioavailability and toxicity of the antibiotic, demonstrating complex mixture effects in aquatic systems.
Meta-analysis unravels the complex combined toxicity of microplastics and antibiotics in aquatic ecosystems
A meta-analysis of 730 datasets found that microplastics amplify antibiotic accumulation in aquatic organisms and worsen effects on growth, development, and immune function, but paradoxically appear to mitigate reproductive toxicity from antibiotics. The impact depends on biological response pathway, microplastic concentration, antibiotic properties, and exposure time, with an inverse relationship between antibiotic toxicity and both microplastic concentration and exposure duration.
Microplastics and Antibiotics in Aquatic Environments: A Review of Their Interactions and Ecotoxicological Implications
This review examines how microplastics and antibiotics interact when they meet in water, and what that means for ecosystems and health. Antibiotics can attach to microplastic surfaces through chemical bonds, and the microplastics can then carry these drugs through the environment, potentially spreading antibiotic-resistant bacteria. While the combined threat to fish and other aquatic life needs more study, the findings raise concerns about how microplastics help move antibiotic resistance through water systems.
Impact of sulfamethoxazole on a riverine microbiome
Scientists studied how the antibiotic sulfamethoxazole affects the microbial community in a river, finding that even low concentrations shifted the balance of bacteria and promoted antibiotic resistance genes. This is relevant to the microplastic field because both antibiotics and microplastics promote antibiotic resistance when they co-occur in aquatic environments.
Ecotoxicology of microplastics in water ecosystems and aquatic organisms: A review of synergistic and antagonistic effects of microplastics on other xenobiotics
This review examines the ecotoxicological effects of microplastics in aquatic ecosystems, focusing on how they interact with other pollutants like heavy metals, organic contaminants, and pathogens. The study highlights that microplastics can adsorb and transport these pollutants through synergistic or antagonistic interactions, leading to oxidative stress, endocrine disruption, and reproductive impairment in exposed organisms, with potential for biomagnification up the food chain.
The impact of microplastic and sulfanilamide co-exposure on soil microbiota
This study investigated what happens when microplastics and the antibiotic sulfanilamide are present together in soil, finding that the combination significantly altered soil microbial communities compared to either pollutant alone. Both conventional polyethylene and biodegradable polylactic acid microplastics interacted with the antibiotic to change bacterial diversity and soil chemistry. The results show that microplastics and antibiotics in agricultural soil can have compounding effects on soil health, potentially affecting the crops grown in it.

Polyethylene microplastics interfere with the nutrient cycle in water-plant-sediment systems
Researchers studied how polyethylene microplastics affect nutrient cycling in freshwater systems containing submerged plants and sediment.
