Combined effects of microplastics and copper on antioxidant capacity, gut microbiome, and metabolomics of Pseudorasbora parva
Researchers studied the combined effects of microplastics and copper on the freshwater fish Pseudorasbora parva, examining antioxidant capacity, gut microbiota, and metabolic responses. They found that the presence of microplastics alongside copper actually reduced copper accumulation in tissues and lessened oxidative damage compared to copper exposure alone. The study suggests that while microplastics can alter the toxicity profile of metals in fish, the interactions are complex and involve metabolic adjustments that balance cellular repair and energy expenditure.

Mechanisms of Gills Response to Cadmium Exposure in Greenfin Horse-Faced Filefish (Thamnaconus septentrionalis): Oxidative Stress, Immune Response, and Energy Metabolism
This study examined how cadmium, a toxic heavy metal from industrial pollution, damages the gills of a marine fish species by triggering oxidative stress, immune responses, and energy imbalances. While not directly about microplastics, the findings are relevant because microplastics can absorb and transport heavy metals like cadmium into aquatic food chains. Understanding how fish respond to cadmium exposure helps assess the combined risks when heavy metals hitchhike on microplastic particles.
Effects of polystyrene nanoplastics and copper on gill tissue structure, metabolism, and immune function of the Chinese mitten crab (Eriocheir sinensis)
This study found that nanoplastics and copper together caused more damage to crab gill tissue than either pollutant alone, disrupting the animals' antioxidant defenses, metabolism, and immune function. The combined exposure suppressed important detoxification genes that help the crabs cope with environmental stress. Since crabs are a common seafood, these findings raise concerns about how co-occurring pollutants in waterways could affect both aquatic life and the safety of shellfish for human consumption.
