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.

This study was conducted to determine the arsenic concentration in two fish samples, including Shurideh and Kafshak, supplied in the city of Isfahan.
Keywords: Arsenic, fish, atomic absorption spectrometry, heavy metals Introduction Heavy metals are environmental pollutants whose exposure to humans through water and food can cause dangerous chronic and sometimes acute toxicities, including metals such as lead, cadmium, mercury, nickel, arsenic, zinc, aluminum, copper, and iron.
Therefore, given the importance of the subject and the potential hazards of heavy metals, including arsenic, on human health, the present study was conducted with the aim of determining the arsenic concentration status in two highly consumed fish species distributed in the Isfahan county market.
(1992), by examining 15 aquatic species including various types of fish and marine crustaceans caught from the Arabian Gulf, reported the arsenic concentration level in the aforementioned samples from 0.
(2005) in Norway, and Burger and Gochfeld (2005) in the USA reported the total arsenic concentration in various commercially important fish and their products in the ranges of 3.
(2008) from the USA reported the arsenic concentration among various marine aquatic organisms, including various types of fish and crustaceans, in the range of 0.
