Differential hepatic metal and metallothionein levels in three Feral fish species along a metal pollution gradient.
The accumulation of cadmium, copper and zinc and the induction of metallothioneins (MT) in liver of three freshwater fish species was studied.Gudgeon (Gobio gobio), roach (Rutilus rutilus) and perch (Perca fluviatilis) were captured at 6 sampling sites along a cadmium NATURAL STEVIA and zinc gradient and one reference site in a tributary of the Sch
