Abstract :

  Heavy metal contaminants in fish are of particular interest because of their potential risk to human. This study was undertaken to determine the levels of arsenic in two fish type including tiger tooth croaker and Indian halibut  in Esfahan. A total of 42 fish samples including 28 tiger tooth croaker (Otolithes ruber) and 14 Indian halibut (Psettodes erumei) were collected from retails of Esfahan from May 2010 to January 2011. For detection of arsenic contamination, the edible muscles of  fish samples were analyzed by hydride generation atomic absorption spectrophotometer. The arsenic contamination in fish samples were found to be in the range of 11 to 98 µg/kg. Concentration of arsenic in tiger tooth croaker and Indian halibut was 11-56 and 32-98 µg/kg, respectively. Arsenic concentrations were below the limit was acceptable to the World Health Organization. According to the results, the concentration of arsenic did not exceed the maximum acceptable intake limit.
