Bioaccumulation of Some Heavy Metals in the Liver Flukes Fasciola hepatica and F. gigantica.

Background: Heavy metals tend to bioaccumulate in living organisms, and their accumulation has been a major concern. As mammals are known to excrete heavy metals via their bile, it seems to be very promising to analyse metal burdens of parasites that infect the biliary tree such as liver flukes of the genus Fasciola. The present study was carried out to evaluate F.
