Background: Nowadays, the pollution of aquatic ecosystems caused by entry of heavy metals is an
issue that makes it essential to check the wholesome of the aquatic animals that are consumed by
human. When these metals enter the canvas of aquatic organisms, cause tension due to bioavailability,
and their toxicity leads to teratogenic, mutagenic and carcinogenic effects in living organisms
Methods: Thirty rainbow trout were prepared from each fishing farm pond which are located in
Sanandaj (Nanale Village) and Kamyaran (Diwaznaw Village). Then, samples were prepared using acid
digestion method in the laboratory and the concentration of these metals was measured using atomic
absorption spectrometer (Phonix 986). The achieved data were analyzed using SPSS software..
Results: The average concentration of the copper in liver and muscle tissues was 1. 53 and 0.15, for
magnesium 3.7 and 7.57, for iron 0.28 and 0.6, for zinc 4.52 and 1.05, and for Nickel was 0.04 and
0.03 micro grams per a gram of fresh weight. The maximum daily consumption allowance was 888.7
grams for adults and 177.77 for children
Conclusion: The average concentration of copper, iron, zinc, nickel and magnesium in muscle tissue
of rainbow trout compared to international standards, is slightly lower than that at current
consumption rates, long-term health risks to consumers is realized.
