ClearIndividual 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.
Combined exposure of polystyrene microplastics and carbamazepine induced transgenerational effects on the reproduction of Daphnia magna
Researchers found that combined exposure to polystyrene microplastics and carbamazepine caused enhanced transgenerational reproductive toxicity in Daphnia magna across two generations, with mixture effects significantly worse than individual exposures.
First insight of the intergenerational effects of tri-n-butyl phosphate and polystyrene microplastics to Daphnia magna
Researchers studied the combined effects of polystyrene microplastics and the flame retardant tributyl phosphate on water fleas across multiple generations. They found that co-exposure caused more severe impacts on survival, growth, and reproduction than either contaminant alone, with effects persisting into subsequent generations. The study suggests that microplastics carrying adsorbed chemicals may pose compounding risks to aquatic organisms over time.
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.
Antagonistic effects of copper and microplastics in single and binary mixtures on development and reproduction in the freshwater cladoceran Daphnia carinata
Combined exposure of the freshwater cladoceran Daphnia carinata to polyethylene microplastics and copper showed antagonistic effects on survival and reproduction, with microplastics reducing the bioavailability of copper through adsorption, resulting in lower combined toxicity than copper alone at some concentrations.
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.
Effects of Exposure to Cadmium, Microplastics, and Their Mixture on Survival, Growth, Feeding, and Life History of Daphnia magna
Researchers examined how polyethylene microplastics altered cadmium toxicity to Daphnia magna, finding that microplastic co-exposure modified cadmium bioavailability and affected survival, growth, feeding rates, and reproductive outcomes in this ecologically important species.
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.
Toxicological interactions induced by chronic exposure to gold nanoparticles and microplastics mixtures in Daphnia magna
This study examined the combined toxicological effects of gold nanoparticles and microplastics through chronic exposure, finding interactive effects that differed from either contaminant alone, emphasizing the importance of studying multiple stressors together.
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.
The effect of microplastics and co-occurring toxicants on survival and life-history traits of the cladoceran Moina macrocopa
Researchers tested the effects of four types of microplastics on the freshwater cladoceran Moina macrocopa, both alone and in combination with copper, insecticides, and diesel fuel. The study found that only polystyrene-based microplastics induced direct toxicity, while other polymer types modulated the toxicity of co-occurring chemical contaminants in varying ways.
Evaluating additive versus interactive effects of copper and cadmium on Daphnia pulex life history
This study assessed how two common heavy metals — copper and cadmium — combine to affect the water flea Daphnia pulex under different food conditions and across multiple genotypes. Understanding metal mixture toxicity is relevant to assessing microplastic risk because plastics often carry multiple metals adsorbed from seawater.
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 effects of polystyrene microplastics and copper on antioxidant capacity, immune response and intestinal microbiota of Nile tilapia (Oreochromis niloticus)
Researchers examined the combined effects of polystyrene microplastics and copper on Nile tilapia and found that co-exposure increased copper accumulation in the liver and caused tissue damage in multiple organs. High concentrations of both contaminants together triggered oxidative stress, inflammation, and shifts in intestinal microbial communities. The study suggests that microplastics can worsen the toxic effects of heavy metals on freshwater fish.
Combined Effects of Polystyrene Nanoplastics and Enrofloxacin on the Life Histories and Gut Microbiota of Daphnia magna
Researchers exposed Daphnia magna to polystyrene nanoplastics and the antibiotic enrofloxacin alone and in combination, measuring life history traits and gut microbiota responses. Both stressors individually reduced survival and reproduction, and combined exposure altered the taxonomic composition and metabolic function of gut microbiota more than either contaminant alone.
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.
Combined effect of polystyrene nanoparticles and chlorpyrifos to Daphnia magna
This study examined the combined effects of polystyrene nanoparticles and chlorpyrifos pesticide on Daphnia magna, a standard aquatic toxicity test organism. The two contaminants together caused greater mortality and reproductive impairment than either alone, suggesting synergistic toxicity.
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.
Combined exposure of polystyrene microplastics and carbamazepine induced transgenerational effects on the reproduction of Daphnia magna
Researchers found that combined exposure to polystyrene microplastics and the pharmaceutical carbamazepine caused transgenerational reproductive toxicity in water fleas, with the second generation showing significantly reduced offspring numbers and disrupted expression of reproduction-related genes.
Microplastics but not natural particles induce multigenerational effects in Daphnia magna
Daphnia magna were exposed to irregular polyethylene microplastics across multiple generations and compared to naturally occurring mineral particles of similar size; microplastics caused multigenerational reductions in reproduction and body size while natural particles did not, demonstrating particle-type-specific chronic effects.
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.
Multigenerational effects of co-exposure to dimethylarsinic acid and polystyrene microplastics on the nematode Caenorhabditis elegans
Researchers found that co-exposure to dimethylarsinic acid and polystyrene microplastics across five generations of C. elegans nematodes caused cumulative harm, with microplastics reducing detoxification capacity and arsenic impairing growth more severely than either pollutant alone.
Long-term effects of individual and combined exposure to microplastics and copper in zebrafish hypothalamic-pituitary-gonadal axis – A multi-biomarker evaluation
This study exposed zebrafish to microplastics, copper, and both combined for 30 days and examined effects on their reproductive system. The combination of microplastics and copper caused greater hormonal disruption and oxidative stress than either pollutant alone, affecting genes that control reproduction in both male and female fish. These findings suggest that microplastics interacting with metal pollution in waterways could compound reproductive harm in aquatic organisms and potentially in humans who consume contaminated fish.
Study of the toxicological effects of emerging contaminants on Daphnia similis associating polyethylene microplastics with the agrochemical imidacloprid.
Brazilian researchers tested the ecotoxicological effects of combining polyethylene microplastics with the insecticide imidacloprid on the freshwater crustacean Daphnia, finding combined exposures were more toxic than either pollutant alone. These results suggest that microplastics and pesticides together pose greater risks to aquatic organisms than studies of single pollutants indicate.
