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.
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.
Additive effects of microplastics on accumulation and toxicity of cadmium in male zebrafish
Researchers exposed adult zebrafish to polyethylene microplastics and cadmium, both individually and in combination, for 21 days. They found that microplastics and cadmium together produced additive toxic effects, increasing cadmium accumulation in fish tissues, altering behavior, and causing more severe organ damage. The study suggests that microplastics in contaminated waterways may worsen the harmful effects of heavy metals on aquatic life.
Effects of microplastics and their adsorption of cadmium as vectors on the cladoceran Moina monogolica Daday: Implications for plastic-ingesting organisms
Scientists examined how polyethylene microplastics adsorb cadmium and then tested the combined effects on the water flea Moina monogolica over 21 days, finding that cadmium-laden microplastics caused greater reproductive and developmental harm than either stressor alone.
Single and combined acute and subchronic toxic effects of microplastics and copper in zebrafish (Danio rerio) early life stages
Researchers exposed zebrafish embryos and larvae to microplastics, copper, and their combinations to assess individual and combined toxic effects. They found that microplastics alone caused limited harm, but when combined with copper, the mixture produced altered biochemical responses and changes in gene expression. The study suggests that microplastics can modify the toxicity of heavy metals in aquatic organisms during early development.
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.
Short- and long-term single and combined effects of microplastics and chromium on the freshwater water flea Daphnia magna
Researchers investigated the individual and combined effects of microplastics and chromium on the water flea Daphnia magna in both short- and long-term experiments. They found that microplastics interacted with chromium, reducing its concentration in water, and that co-exposure caused acute toxicity but lacked the chronic effects seen with chromium alone. The study suggests that microplastics may alter the bioavailability and toxicity of metal pollutants in freshwater environments.
Multi-Biomarker Responses of Asian Clam Corbicula fluminea (Bivalvia, Corbiculidea) to Cadmium and Microplastics Pollutants
Researchers exposed Asian clams to cadmium, microplastics, and their mixtures, then measured a battery of biomarkers including oxidative stress, energy metabolism, and neurotoxicity indicators. They found that the combined exposure to cadmium and microplastics produced interactive effects that differed from exposure to either contaminant alone. The study demonstrates that microplastics can modify the toxicity of heavy metals in freshwater bivalves, highlighting the importance of studying pollutant mixtures rather than individual contaminants.
Action of Surfactants in Driving Ecotoxicity of Microplastic-Nano Metal Oxides Mixtures: A Case Study on Daphnia magna under Different Nutritional Conditions
This study tested how surfactants (found in detergents and cleaning products) interact with microplastics and metal oxide nanoparticles to affect the toxicity of these combined pollutants on water fleas (Daphnia magna). Surfactants increased the toxicity of microplastic-nanoparticle mixtures, and the effect varied with the age and nutritional status of the test organisms. This highlights how the complex real-world mixture of pollutants in waterways can be more harmful than any single contaminant alone.
