| contents | Evaluating the impact of gadolinium contamination on the marine bivalve Donax trunculus: Implications for environmental health. Secco, Silvia Cunha, Marta Libralato, Giovanni Trifuoggi, Marco Giarra, Antonella Soares, Amadeu M V M Freitas, Rosa Scalici, Massimiliano Animals Gadolinium Water Pollutants, Chemical Bivalvia Lipid Peroxidation Environmental Monitoring Glycogen Contrast Media Gadolinium (Gd), commonly used in contrast agents for medical imaging, has been detected in hospital wastewater and aquatic environments, raising environmental concerns. This study examined the accumulation and cellular impacts of Gd in the clam species Donax trunculus, commonly used as bioindicator of contamination. Gadolinium accumulation in clams increased with exposure and over time. Biological responses varied with Gd levels: low concentrations (10 and 50 µg/L) led to low metabolic activity and glycogen content, but high antioxidant activities and lipid peroxidation levels (LPO); high concentrations (250 and 500 µg/L) resulted in increased metabolic activity, while antioxidant enzyme activity was inhibited and LPO levels were the lowest. Metabolic activity decreased after two weeks, suggesting limited long-term metabolic resilience. The study underscores D. trunculus as an effective early warning species for Gd pollution and highlights the ecological risks of rising Gd levels, emphasizing the need for environmental monitoring and regulation. |
