ABSTRACT
Among amphetamine like stimulants (ATS), the 3,4-methylenedioxymethamphetamine (MDMA) is often detected in sewage and surface waters, representing a potential threat for organisms because of its peculiar mechanism of action (i.e., stimulatory and hallucinogenic). The present study aimed at investigating biochemical (i.e., oxidative stress and energetic biomarkers) and behavioral (i.e., swimming activity) effects induced by a 21-days exposure to two concentrations (50 ng/L and 500 ng/L) of MDMA towards Daphnia magna. The amount of reactive oxygen species (ROS), the activity of antioxidant (SOD, CAT, GPx) and detoxifying (GST) enzymes and lipid peroxidation were measured as oxidative stress-related endpoints. Total energy content was estimated from the measurement of protein, carbohydrate and lipid content to assess energy reserves. The modulation of swimming activity was assessed as behavioral endpoint. Slight effects of MDMA exposure on oxidative stress responses and energy reserves were observed, while no alterations of the swimming behavior was noted.
