ClearExploring the combined toxic effects of tri-n-butyl phosphate and polystyrene micro/nano-plastics on Daphnia magna under environmentally relevant concentrations
Researchers explored the combined toxic effects of the flame retardant tri-n-butyl phosphate and polystyrene micro- and nanoplastics on the water flea Daphnia magna at environmentally relevant concentrations. The study found that co-exposure to both pollutants altered gene expression related to stress responses, suggesting that the combined presence of these emerging contaminants may pose greater risks to aquatic organisms than either pollutant alone.
Combined toxic effects of polystyrene microplastic and benzophenone-4 on the bioaccumulation, feeding, growth, and reproduction of Daphnia magna
Researchers examined the combined toxic effects of polystyrene microplastics and the UV filter chemical benzophenone-4 on water fleas over 21 days. They found that exposure to both contaminants together caused greater harm to feeding, growth, and reproduction than either pollutant alone. The study demonstrates that microplastics and personal care product chemicals can interact to amplify their negative effects on freshwater organisms.

Combined toxicity of perfluoroalkyl substances and microplastics on the sentinel species Daphnia magna: Implications for freshwater ecosystems
This study tested how PFAS chemicals (common industrial pollutants) and PET microplastics affect water fleas, both alone and together. The combination caused worse developmental and reproductive problems than either pollutant alone, and organisms with prior chemical exposure history responded differently, showing that microplastics can amplify the harm of other environmental contaminants in ways that are difficult to predict.
Individual and combined multigenerational effects induced by polystyrene nanoplastic and glyphosate in Daphnia magna (Strauss, 1820)
Researchers investigated the individual and combined effects of polystyrene nanoplastics and the herbicide glyphosate on the freshwater crustacean Daphnia magna across multiple generations. They found synergistic toxicity when the two contaminants were combined, increasing immobility and reactive oxygen species production. Notably, parental exposure to the mixture caused reproductive effects that persisted into subsequent generations even without continued exposure.
Adverse multigeneration combined impacts of micro(nano)plastics and emerging pollutants in the aquatic environment
This review examines how micro and nanoplastics combined with other pollutants can cause harm not just to exposed organisms but also to their offspring across multiple generations. The transgenerational effects include changes in growth, reproduction, and gene expression that persist even without continued exposure. This suggests that microplastic pollution could have long-lasting impacts on wildlife populations beyond what single-generation studies reveal.
Parental exposure to polystyrene nanoplastics and di(2-ethylhexyl) phthalate induces transgenerational growth and reproductive impairments through bioaccumulation in Daphnia magna
Researchers assessed the transgenerational impacts of parental exposure to polystyrene nanoplastics and the plasticizer DEHP on Daphnia magna over four generations. The study found that combined exposure to nanoplastics and DEHP caused growth and reproductive impairments that persisted across generations through bioaccumulation, suggesting that the ecological consequences of nanoplastic and plasticizer co-contamination may extend well beyond directly exposed organisms.
Combined Effect of Polystyrene Particles and Copper Ions on the Vital Parameters of Daphnia Magna in a Series of Generations
Researchers studied the combined effects of polystyrene microplastics and copper ions on Daphnia magna over four generations using both short-term and continuous exposure designs. Toxicity was greater under combined exposure and increased across generations, suggesting cumulative intergenerational harm from mixed pollutant stress.
Intergenerational and biological effects of roxithromycin and polystyrene microplastics to Daphnia magna
Researchers studied the intergenerational effects of the antibiotic roxithromycin combined with polystyrene microplastics on water fleas (Daphnia magna) across multiple generations. They found that UV-aged microplastics altered the carrier effects on the antibiotic compared to pristine particles, changing survival and reproductive outcomes. The study suggests that the aging and weathering state of microplastics in the environment influences how they interact with pharmaceutical pollutants and their combined toxicity.
Tissue translocation, multigenerational and population effects of microplastics in Daphnia magna
This study examined how microplastics are taken up by the water flea Daphnia magna and whether exposure causes multigenerational effects, finding that microplastics can accumulate in body tissues and pass to offspring. The results suggest microplastic pollution poses risks not just to exposed individuals but can affect population health across generations.
Transgenerational effects and recovery of microplastics exposure in model populations of the freshwater cladoceran Daphnia magna Straus
Researchers tracked the effects of microplastic exposure across four generations of Daphnia magna and found that reproductive impairment and growth reductions persisted into offspring generations that were never directly exposed. The study suggests that microplastics can cause transgenerational effects in freshwater organisms, though partial recovery was observed when exposure ceased.
A fit-for-purpose categorization scheme for microplastic morphologies
Researchers studied the long-term effects of polypropylene microplastic exposure on the life history traits of the water flea Daphnia magna across three generations, finding progressively increasing reproductive impairment and reduced survival in successive generations. The multigenerational impacts exceeded those observed in single-generation tests.
Short-term and long-term effects of microplastics and organic UV-filters on the invertebrate model species Daphnia magna
Researchers exposed water fleas to polystyrene microplastics, a mixture of UV-filter chemicals found in sunscreens, or both over 21 days. The microplastics alone reduced body size and reproduction, while combined exposure with UV-filters further impaired swimming behavior and offspring production. The study highlights that microplastics and common personal care product chemicals can interact to create compounding negative effects on freshwater organisms.
Impacts of microplastics and pesticides on Daphnia
Researchers investigated the combined and individual impacts of microplastics and pesticides on Daphnia magna, a model crustacean widely used in freshwater ecotoxicology, to assess how these co-occurring pollutants affect aquatic ecosystem health. The study examined survival, reproduction, and physiological responses in D. magna exposed to varying concentrations of both stressors under controlled conditions.
Detrimental effects of individual versus combined exposure to tetrabromobisphenol A and polystyrene nanoplastics in fish cell lines
Researchers tested how combined exposure to the flame retardant tetrabromobisphenol A and polystyrene nanoparticles affects freshwater fish cells. They found that co-exposure to even low concentrations of both pollutants caused subtle changes in cell viability and generated oxidative DNA damage. The study suggests that the interaction between nanoplastics and chemical pollutants in aquatic environments may pose compounding risks to fish health.
Toxicological effects of microplastics and heavy metals on the Daphnia magna
Researchers studied how polystyrene microplastics of two sizes adsorb heavy metals and how their combined presence affects the water flea Daphnia magna. They found that smaller microplastics had higher adsorption capacity for metals, and the combined toxicity shifted from antagonistic to additive effects as microplastic concentrations increased. The study reveals that smaller microplastics pose a greater toxicological risk when combined with heavy metals in aquatic environments.
Multigenerational effects of combined exposure of triphenyltin and micro/nanoplastics on marine medaka (Oryzias melastigma): From molecular levels to behavioral response
This study exposed marine medaka fish to a combination of micro/nanoplastics and triphenyltin, a toxic chemical used in paints and plastics. The pollutants caused oxidative stress, hormone imbalances, and behavioral changes that carried over to the next generation of fish. The findings show that microplastics combined with other environmental pollutants can cause harm that gets passed down to offspring, raising concerns about long-term effects on marine food webs.
Microplastic fiber-induced transgenerational epigenetic disruption impairs fitness in Daphnia magna
Researchers investigated the multi-generational effects of microplastic fiber exposure on the water flea Daphnia magna across three generations. They found that microplastic fibers negatively affected reproduction and survival, and these effects persisted into unexposed generations through epigenetic changes. The study reveals that microplastic pollution may cause lasting harm to aquatic populations through inherited biological alterations, not just direct exposure.
Changes of the acute and chronic toxicity of three antimicrobial agents to Daphnia magna in the presence/absence of micro-polystyrene
Polystyrene microplastics alone caused chronic reproductive toxicity to Daphnia magna at low milligram-per-liter concentrations and worsened the reproductive harm caused by three antimicrobial compounds (triclosan, triclocarban, and methyl-triclosan) in a concentration-dependent manner. The findings suggest microplastics can amplify the chronic toxicity of co-occurring pollutants to aquatic invertebrates.
Synergistic toxic mechanisms of microplastics and triclosan via multixenobiotic resistance (MXR) inhibition–mediated autophagy in the freshwater water flea Daphnia magna
Researchers exposed water fleas to microplastics and triclosan, a common antimicrobial chemical, and found that the combination was more toxic than either pollutant alone. Microplastics interfered with the organisms' natural defense system for expelling foreign chemicals, allowing triclosan to accumulate and trigger harmful autophagy. This suggests that microplastics may amplify the toxicity of other environmental contaminants in aquatic ecosystems.
Transgenerational effects of polyethylene microplastic fragments containing benzophenone-3 additive in Daphnia magna
Researchers investigated the transgenerational effects of polyethylene microplastic fragments containing the UV filter benzophenone-3 on water fleas (Daphnia magna) across four generations. They found that while mortality effects recovered by the third unexposed generation, reproductive impairments persisted, with the additive BP-3 contributing more to long-term toxicity than the plastic particles alone. The study suggests that chemical additives in microplastics may pose lasting risks to aquatic organisms even across generations that were never directly exposed.
Primary and Secondary Plastic Particles Exhibit Limited Acute Toxicity but Chronic Effects on Daphnia magna
Researchers investigated the chronic effects of both primary nanoplastics (polystyrene nanospheres) and secondary micro- and nanoplastics from weathered single-use plastics on Daphnia magna across multiple generations. The study found that nanoplastics accumulated in the intestine and brood chamber, transferred to offspring, and reduced reproduction and physiological function, with effects persisting across generations even after exposure ended.
Combined Toxicity of Polystyrene Nanoplastics and Pyriproxyfen to Daphnia magna
Researchers evaluated the combined toxic effects of polystyrene nanoplastics and the insecticide pyriproxyfen on the water flea Daphnia magna under both acute and chronic exposure conditions. They found that nanoplastics initially reduced the acute toxicity of the pesticide within 24 hours but worsened chronic effects over longer periods. The study suggests that nanoplastics can alter how other environmental contaminants affect aquatic organisms, complicating risk assessments.
