Effect of polystyrene microplastics and temperature on growth, intestinal histology and immune responses of brine shrimp Artemia franciscana
AI summary Read the abstract
Researchers exposed brine shrimp to polystyrene microplastics at different temperatures, finding that higher plastic concentrations combined with warmer water reduced survival, damaged intestinal tissue, and triggered immune stress responses — suggesting climate change may amplify microplastic harm in marine ecosystems.
Impact of ingested microplastics on phenotypic traits and biochemical parameters in Nile tilapia (Oreochromis niloticus) juvenile
AI summary Read the abstract
Juvenile Nile tilapia exposed to microplastics showed significantly lower survival rates, reduced body weight, smaller eye diameter, elevated superoxide dismutase activity, and reduced catalase activity compared to controls, indicating physiological stress and impaired antioxidant defense. These dose-response effects on a widely farmed species provide direct evidence that microplastic ingestion compromises fish growth and survival, with implications for aquaculture productivity and the integrity of fish-based food systems.
Individual and Combined Toxicity of Polystyrene Microplastics and Chromium in Artemia franciscana: Impacts on Survival, Growth, Biochemical and Physiological Responses
AI summary Read the abstract
A 21-day exposure study found that polystyrene microplastics and chromium individually and synergistically impaired survival, growth, protein levels, and antioxidant defenses in the brine shrimp Artemia franciscana, with combined toxicity exceeding either contaminant alone. This demonstrates that microplastics act as carriers and amplifiers of heavy metal toxicity in aquatic organisms, raising concerns about real-world ecosystems where both pollutants co-occur.
Assessment of microplastic hazards in Penaeus vannamei shrimp in a typical estuary of China: polymer composition, risk assessment, and health implications
AI summary Read the abstract
Researchers assessed microplastic contamination in whiteleg shrimp from the Jiulong River estuary in China, finding five polymer types at 0.46 particles/g, with PVC comprising only 5.52% by count but contributing 98.11% of the total hazard risk index due to its toxic chemical additives. The disproportionate hazard posed by PVC despite its low abundance in farmed shrimp has direct food-safety implications, as commercially important shellfish in estuarine aquaculture systems are accumulating high-risk plastics consumed by people globally.
