Kinetics of mercury accumulation and elimination in edible glass eel (Anguilla anguilla) and potential health public risks
Mercury (Hg) bioaccumulation and depuration potential was assessed in the glass eel Anguilla anguilla over a 30-day period, through a mesocosm experiment. During exposure period, glass eels exhibited a significant increase in Hg concentration compared with the control ones, revealing great accumulat...
