Bioaccumulation Level of Zinc in Different Tissues of Common Carp Cyprinus carpio-prone sublethal concentrations

Abstract

Cyprinus carpio were exposure to three sublethal concentrations of zinc 0.05, 0.1
and 1 mg/l ZnCl2 as well as control treatments, during periods of ( 1, 7, 14 and 21) days of
exposure. Concentration levels of zinc were determined in gills, liver, and kidney and
muscle tissues. The highest concentration was recorded in the liver, kidney and gills tissues
respectively for higher exposure concentration of zinc during (14 and 21) days of
experiment, while, the muscle tissue was accumulated lower values of zinc in comparison
with control samples.
