Interação entre estresse térmico e benzofenona-3 em Seriatopora caliendrum: respostas bioquímicas e celulares
Coral reefs are threatened by rising ocean temperatures and emerging contaminants such as the UV filter benzophenone-3 (BP-3). This study evaluated the effects of chronic exposure (96h) to 50% EC50-96h for BP-3 (2 mg/L) combined with thermal stress (26 and 30 °C) on biomarkers in Seriatopora caliendrum: lipid peroxidation (TBARS), DNA damage, and lysosomal membrane stability. Temperature affected lipid peroxidation, and lysosomal stability was affected by temperature, BP-3, and their interaction (p<0.001), indicating synergism. No effect was found on DNA. Lysosomal stability proved to be an early, sensitive biomarker of combined stress, reinforcing concerns about cumulative risks under global warming scenarios.
