|abstract: ||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 accumulation
capability. Distinct bioaccumulation kinetics
were observed depending on the exposure concentrations:
a saturation model and a linear accumulation
model were achieved for low and high Hg levels, respectively.
After 72 h of depuration, glass eels lost
around 2 and 10 % of the Hg previously accumulated;
however, until the end of the experiment, they never
reached the original baseline condition. Most importantly,
organisms exposed to high Hg concentrations still
retained contaminant levels exceeding the European
threshold regulating human food consumption. This
may raise serious health concerns, due to the species’
rising interest in the international cuisine.|
