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.
Exposure scenarios modulate the combined toxicity of nanoplastics and Cd to Daphnia magna
Researchers evaluated how different exposure scenarios (single, pre-exposure, and co-exposure) affect the combined toxicity of nanoplastics and cadmium to the water flea Daphnia magna. The study found that environmentally relevant concentrations of nanoplastics initially stimulated reproduction, but the timing and sequence of exposure significantly influenced bioaccumulation, intestinal damage, and gut microbiota disruption.
Ecotoxicological Effects of Polyvinyl Chloride (PVC) Microplastics on the Growth, Reproduction and Survival of Daphnia magna
Researchers exposed Daphnia magna to polyvinyl chloride microplastics at different concentrations, alone and combined with two algal food sources, and measured growth, reproduction, and survival. PVC microplastics reduced fecundity and survival in a dose-dependent manner, with food source type modulating the severity of toxicity effects.
Effects of Microplastics on Reproduction and Growth of Freshwater Live Feeds Daphnia magna
Researchers found that microplastic exposure negatively affected reproduction and juvenile growth in Daphnia magna, a key freshwater zooplankton species, with effects worsening at higher concentrations and posing risks for aquatic food chains.
Assessment of intake and effect of microplastics and its combination with metals in experimental (Daphnia magna) and environmental conditions (freshwater fish)
Researchers assessed the intake and effects of microplastics and their combination with metals using Daphnia magna as an experimental model and freshwater fish under environmental conditions, investigating how microplastics adsorb and transport harmful metals in freshwater systems.
Effects of chronic exposure to microplastics and microplastics associated with polychlorinated biphenyl 153 on Daphnia magna
A 21-day chronic exposure study found that polyethylene microbeads alone and in combination with PCB-153 affected survival and reproduction of Daphnia magna, with the combined exposure producing more pronounced reproductive impairment than either pollutant alone.
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.

This study evaluated the combined impacts of microplastics and cadmium on biochemical biomarkers in a freshwater organism, finding that co-exposure caused greater oxidative stress and cellular damage than either contaminant alone. Microplastics appear to enhance cadmium bioavailability and toxicity.
Is the development of Daphnia magna neonates affected by short-term exposure to polyethylene microplastics?
Daphnia magna neonates ingested polyethylene microplastics within the first 24 hours of exposure but showed no significant effects on mobility or molting, though food availability was a more powerful driver of development than microplastic concentration. The study highlights the importance of accounting for feeding regime when interpreting microplastic toxicity tests.
Ecotoxicology of microplastics in Daphnia: A review focusing on microplastic properties and multiscale attributes of Daphnia
This review synthesizes research on how microplastics affect Daphnia, a key organism in aquatic food webs, across individual, population, and community levels. Researchers found that the toxicity of microplastics to Daphnia depends heavily on the physical and chemical properties of the particles, and that combined exposure with other pollutants can produce more severe effects. The study highlights Daphnia as an important indicator species for understanding how microplastic pollution cascades through aquatic ecosystems.
