Pinto, João Cunha, Marta Leite, Carla Soares, Amadeu M V M Freitas, Rosa Pereira, Eduarda Animals Gills Mytilus Water Pollutants, Chemical Yttrium Lipid Peroxidation Digestive System Oxidative Stress The rapid growth of electronic waste, including fluorescent lamp waste (FLW), has led to an increase in elements like yttrium (Y) and other rare earth elements (REE) in aquatic environments due to improper waste management. However, there are no guidelines for permissible concentrations of these elements in the environment. This study examines the biochemical impacts of varying Y concentrations (50, 100, and 200 µg L), mimicking a FLW discharge, on the gills and digestive gland of Mytilus galloprovincialis exposed for 14 days. Energy reserves, antioxidant and biotransformation enzymes, lipid peroxidation (LPO), and neurotoxicity were measured. Results showed a limited antioxidant capacity in the gills at the highest Y concentration. Additionally, increased LPO levels in both organs suggest oxidative stress-induced damage. The study underscores the need for regulations to address Y contamination and safeguard aquatic ecosystems, proposing a reference value for permissible concentrations based on the observed effects. |
