| Catfish of Anzali wetland has been focused economically and commercially. It also meets the religious Minorities needs to fish meat. So, investigation of its health in the wetland is important. This study aimed to investigate the concentration of heavy metals such as cadmium, Nickle, Zinc and lead in muscle tissues of Catfish in three stations (west, central and east) of Anzali wetland in 2012. In this study, 10 samples having standard weights were selected randomly from each station by fishing net. The atomic absorption set was used to measure the concentrations of heavy metals. The results showed that the average concentration of cadmium in Catfish was 0.05 and 0.02 microgram / dry weight in west and central wetland, respectively. This was not distinguishable in the east wetland by set. It was found that the average concentrations of Nickle in S.Glanis were 0.18 , 0.1 and 0.09 microgram /gr dry weight in west, central and east wetlands, respectively. Also, the average concentrations of zinc in S.Glanis were 26.35, 20.25 and 22.3 microgram /gr dry weight in west, central and east wetland, respectively. The average concentrations of lead in Catfish were 0.49, 0.5 and 1.11 microgram /gr dry weight in the west, central and east wetland, respectively. In this study, concentrations of cadmium, Nickle, zinc and lead in Catfish were not significant among the studied stations (P > 0.05). Cadmium, Nickle, Zinc and lead levels were compared with standards determined by food and Drug of America (FDA) and world health organization (WHO). Results showed that levels of Cd, Ni, Zn toxicities were fewer than the standards reported by FDA and WHO. However Pb concentration was observed more than the allowed limit (WHO = 0.5) in the east wetland, this needs more investigations. | ||
