The Determination of Khramulia Capoeta capoeta Mercury Concentration in Zarrin Gol River, Golestan Province

In this paper، the concentrations of mercury in the khramulia (Capoeta capoeta) from three stations of the Zarrin Gol River of the province of Golestan are presented. The average of mercury levels in muscle tissue from the stations of 1، 2 and 3 were 173. 79 ± 19. 32، 153. 11± 7. 61 and 172. 25± 12. 69 ng/g dry weight، respectively. No Significant difference was observed in the mean concentrations of Hg among the stations and also no correlations among body weight total length and standard length and Hg were detected in this study (p > 0. 05). All samples had mean mercury concentration less than recommended maximum Hg limit for human consumption set by World Health Organization (WHO)، Environmental Protection Agency (EPA)، Expert Committee on Food Additives (JECFA)، Food and Agriculture Organization (FAO) and the Standardization Administration of China (SAC). It seems this is first study on Capoeta capoeta species with this point of view.
