Level of trace metals in Tilapia Fish of three Lakes in Ethiopia

This manuscript presents the level of some selected trace metals in Tilapia fish (Oreochromis niloticus species) sampled from three productive Ethiopian rift valley lakes. Analytical procedures are clearly shown and reasonable explanations have been made based on the experimental data obtained and other previous works. The result is compared with international standards so that the health and environmental implication of the heavy metals in the fish could be clearly understood.
