ClearMicroplastics aggravate the bioaccumulation and corresponding food safety risk of antibiotics in edible bivalves by constraining detoxification-related processes
Researchers found that microplastics increased the accumulation of antibiotics in three commercially important species of edible shellfish. The microplastics interfered with the animals' natural detoxification processes, making it harder for them to clear antibiotic residues from their tissues. The study raises food safety concerns, suggesting that microplastic-contaminated coastal waters could lead to higher antibiotic levels in the seafood people consume.
Microplastics Aggravate the Bioaccumulation of Two Waterborne Veterinary Antibiotics in an Edible Bivalve Species: Potential Mechanisms and Implications for Human Health
Researchers investigated how microplastics affect the bioaccumulation of two veterinary antibiotics, oxytetracycline and florfenicol, in the edible blood clam. The study found that microplastic co-exposure aggravated antibiotic accumulation in the clams, raising concerns about increased health risks for consumers of contaminated shellfish.
Nano-scale and micron-scale plastics amplify the bioaccumulation of benzophenone-3 and ciprofloxacin, as well as their co-exposure effect on disturbing the antioxidant defense system in mussels, Perna viridis
Researchers studied how nano- and micro-sized plastic particles affect the accumulation of benzophenone-3 and the antibiotic ciprofloxacin in green mussels. They found that smaller plastic particles enhanced the uptake of both chemicals into mussel tissues and caused greater disruption to the animals' antioxidant defense systems. The study demonstrates that plastic particle size matters when assessing how microplastics transport and amplify the effects of other environmental contaminants in marine organisms.
Size-dependent effects of microplastics on intestinal microbiome for Perna viridis
Researchers found that the size of microplastic particles determines how they change the gut bacteria of green mussels, with the smallest particles causing the most disruption to beneficial bacteria and promoting potentially harmful species. Since mussels are widely consumed as seafood, changes to their gut health and the bacteria they carry could affect human food safety.
Combined toxic effects of nanoplastics and norfloxacin on mussel: Leveraging biochemical parameters and gut microbiota
Researchers exposed mussels to nanoplastics and the antibiotic norfloxacin, both alone and together, and found that the combination caused greater biochemical stress than either pollutant alone. Nanoplastics appeared to carry the antibiotic into mussel tissues, increasing its bioavailability and impact on gut microbiota. The findings suggest that nanoplastics can amplify the toxicity of other contaminants in marine organisms.
Microplastics aggravate the bioaccumulation of three veterinary antibiotics in the thick shell mussel Mytilus coruscus and induce synergistic immunotoxic effects
Researchers studied how polystyrene microplastics interact with three common veterinary antibiotics in thick shell mussels. The study found that when microplastics and antibiotics were present together, mussels accumulated significantly more antibiotics in their tissues and suffered worse immune damage than from either pollutant alone. This synergistic effect included reduced immune cell counts, increased oxidative stress, and disrupted immune gene expression, suggesting that microplastic pollution may amplify the harmful effects of antibiotic contamination in coastal waters.
Unraveling the toxic trio: Combined effects of thifluzamide, enrofloxacin, and microplastics on Mytilus coruscus
Researchers examined the combined effects of the pesticide thifluzamide, the antibiotic enrofloxacin, and polystyrene microplastics on mussels over four weeks. They found that co-exposure increased the accumulation of both chemicals in mussel tissue and worsened oxidative damage, neurotoxicity, and metabolic disruption compared to single exposures. The study suggests that the presence of microplastics in waterways can amplify the harmful effects of pesticides and antibiotics on edible shellfish.
Bioaccumulation of emerging contaminants in mussel (Mytilus galloprovincialis): Influence of microplastics
Researchers investigated whether microplastics influence the bioaccumulation of emerging contaminants in Mediterranean mussels. The study found that the presence of microplastics altered how certain chemical pollutants accumulated in mussel tissue, suggesting that microplastics can act as carriers that change the uptake and distribution of other contaminants in marine organisms.
Combined exposure of the bivalve Mytilus galloprovincialis to polyethylene microplastics and two pharmaceuticals (citalopram and bezafibrate): Bioaccumulation and metabolomic studies
Researchers exposed Mediterranean mussels to polyethylene microplastics combined with two pharmaceutical drugs and found that the microplastics altered how the drugs accumulated in mussel tissue and changed the organisms' metabolic responses. The combined exposures caused different metabolic disruptions than single exposures, and not all effects were reversed after a recovery period. This highlights how microplastics in the ocean can interact with pharmaceutical pollution to create unexpected biological effects in seafood species.
Qualitative Assessment and Management of Microplastics in Asian Green Mussels (Perna viridis) Cultured in Bacoor Bay,Cavite, Phillipines
Green mussels cultured in Bacoor Bay in the Philippines were found to contain microplastics, which can accumulate persistent organic pollutants in the tissues of filter-feeding shellfish. Since green mussels are widely consumed as food, the findings raise food safety concerns about the combined exposure to microplastics and associated chemical contaminants.
Impacts of microplastics exposure on copepod (Eurytemora affinis) and mussel (Mytilus edulis) gut microbiota
Researchers studied how microplastic exposure affects the copepod Eurytemora affinis and the mussel Mytilus edulis, examining effects on feeding, reproduction, and overall health at relevant environmental concentrations. Results showed microplastics impaired physiological functions in both species, with additional risks from microorganism-colonized plastic surfaces.

Researchers exposed marine mussels (Mytilus edulis) to microplastics and analyzed changes to their gut microbiota, finding significant shifts in microbial community composition that could affect digestion, immunity, and overall health.
Microplastic-mediated antibiotic migration and bioaccumulation in aquaculture: Implications for seafood safety
This study examined whether microplastics in aquaculture water absorb antibiotics and then increase the amount of those drugs that accumulate in shrimp tissue, finding that shrimp exposed to antibiotic-loaded polyethylene and polypropylene microplastics had higher antibiotic concentrations in their bodies than shrimp exposed to antibiotics alone. Smaller microplastic particles adsorbed less antibiotic, and aged plastics bound more. The findings suggest that microplastics in fish farms create an indirect pathway for antibiotic accumulation in seafood beyond what direct water exposure would produce.
Microplastic accumulation in New Zealand green-lipped mussels Perna canaliculus and the role of microplastics in the uptake of triclosan
This thesis conducted the first study of microplastic accumulation in New Zealand green-lipped mussels (Perna canaliculus), a commercially important aquaculture species, finding plastic particles in mussels from both farmed and wild populations. The results have implications for food safety and the sustainability of New Zealand's shellfish aquaculture industry.
Microplastic-Mediated Transfer of Tetracycline Resistance: Unveiling the Role of Mussels in Marine Ecosystems
Researchers found that microplastics can serve as platforms for antibiotic-resistant bacteria to form biofilms in marine environments, facilitating the transfer of resistance genes. In experiments with mussels, polyethylene microplastics significantly increased the rate at which tetracycline resistance genes spread between bacteria. The findings raise concerns that microplastic pollution in the ocean could accelerate the spread of antibiotic resistance, with implications for both ecosystem and public health.
Effect of microplastics on oxytetracycline trophic transfer: Immune, gut microbiota and antibiotic resistance gene responses
When polypropylene microplastics and the antibiotic oxytetracycline were present together in water, the microplastics acted as carriers that increased antibiotic buildup in shrimp and fish through the food chain. This combination caused more gut and liver damage, weakened immune defenses, and promoted the spread of antibiotic-resistant bacteria. The findings highlight that microplastics can make antibiotic pollution worse by helping resistant genes move up the food chain.
THE RELATIONSHIP OF MICROPLASTIC ABUNDANCE IN GREEN MUSSEL Perna viridis AND THE WATERS OF MANGKANG BEACH, SEMARANG
A study of green mussels (Perna viridis) farmed in a coastal area of Semarang, Indonesia found microplastics in both the surrounding water and mussel tissue, with statistical analysis confirming a significant relationship between water contamination levels and mussel body burden. Because green mussels are widely consumed locally, this finding highlights a direct pathway for microplastic exposure through seafood in the region.
The occurrence of microplastic in specific organs in commercially caught fishes from coast and estuary area of east China
Researchers studied how polyethylene microplastics interact with the antibiotic ciprofloxacin in aquatic environments and found that the plastic particles can absorb and concentrate the drug on their surface. The adsorption capacity increased with weathering of the plastic, suggesting that aged microplastics in the environment are more effective carriers of pharmaceutical pollutants. The findings raise concerns that microplastics could transport antibiotics through water systems, potentially contributing to antimicrobial resistance.
When nanoplastics (NPs) meet algae: Heteroaggregates exacerbate bioaccumulation, immunotoxicity, and microbial dysbiosis in the green mussel (Perna viridis)
Researchers exposed green mussels to nanoplastics alone and to heteroaggregates of nanoplastics combined with microalgae, finding that heteroaggregates increased nanoplastic uptake rates by 5.5-fold and tissue accumulation by 2.5-fold, while also exacerbating immunotoxicity and gut microbiota disruption.
Potential risks of microplastics combined with superbugs: Enrichment of antibiotic resistant bacteria on the surface of microplastics in mariculture system
Microplastics in a mariculture (sea farming) system were found to selectively enrich antibiotic-resistant bacteria on their surfaces compared to surrounding water, creating hotspots of antibiotic resistance in food production environments. This dual threat - microplastics acting as both pollutants and carriers of resistant pathogens - has significant implications for seafood safety.
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.
The impact of microplastics on antibiotic resistance genes, metal resistance genes, and bacterial community in aquaculture environment
Researchers discovered that microplastics in fish farming environments carry significantly higher levels of antibiotic resistance genes and disease-causing bacteria like Brucella and Pseudomonas compared to surrounding water. This means microplastics may act as floating platforms that help spread antibiotic-resistant infections through aquaculture, potentially reaching humans who consume the seafood.
