) were detected in this study. The persistence of MTZ and SX in the aqueous environment was estimated at 14 to 139 days and 9 to 88 days, respectively. The single exposure to MTZ induced cardiotoxicity and changes in the swim bladder and tail curvature. MTZ and SX induced sensory and physiological morphometric changes compared to the control. MTZ, alone or combined with SX, affected the larvae's behavior. Our findings contribute to the understanding of the presence, persistence, and ecotoxicity of antimicrobials in aquatic environments.
