Photoaged Microplastics Disrupt the Response of Marine Medaka ( Oryzias melastigma ) to Ocean Acidification: Perspectives from Energy Metabolism and Ammonia Production

Key Points

• Ammonia production decreased by 25.29% due to microplastic interference with energy metabolism.
• The study identified a disruption caused by microplastics impacting physiological adaptation to ocean acidification.
• Exposure was conducted over 90 days with acidified seawater at pH 7.70 and microplastics present at 0.1 mg/L.
• Photoaging of microplastics further worsened toxicity, leading to a notable 32.04% drop in ammonia production.
