If ﬁsh in a water body absorbed the total amount of mercury settling on its surface alone, recorded (ﬁgure). Since mercury accumulation in ﬁsh is without taking into account the drainage basin, the con- a function of age, the level of signiﬁcance increased when regression analysis was performed using an index centration of this xenobiotic accumulated over one year would exceed the maximum allowable value by a factor normalized with respect to ﬁsh age, i.e., mercury con- of
