The consumption of fish is recommended because fish is a basic and good nutritious food that has omega-3 fatty acids due to its cardio-protective effects. This present mini-review accounts for the description of heavy metal in fish and the effect of toxic metals on the human health. Besides, the acid digestion method wasalso discussed in order to identify the best method for applyingin the laboratory analysis. The bestmethod used can reduce the contamination error in the results.
