In water samples of 7 stations, the concentration of aromatic hydrocarbons ranged from 17.12 to 651.79 mg/ L, and Acenaphthene and Naphthylene with the mean concentrations of 42 and 28.83 mg/L, respectively, which were the most abundant aromatic compounds (<i>p</i><0.05). The results indicate the highest and lowest concentrations of total aromatic hydrocarbons in fish caught at station 7 (43&plusmn;2 mg/kg) and station 1 (9.52&plusmn;3.06 mg/kg), respectively. The highest carcinogenesis rate (1.13) and mutation rate (23.49) were found at stations 7 and station 5, respectively. The gradual carcinogenesis rate of Benz [a] pyrene ranged from 0.00003 to 0.0029, and its mean rate in Huralazim wetland reached 0.0027. The gradual mutation risk assessment for Benz [a] pyrene was estimated to be 0.055 (which ranges from 0.034 to 0.061). Most of the hydrocarbon compounds in the sediments have originated from pyrolytic and fossil fuels. According to mutant and carcinogenic standards, the daily consumption of fish in this wetland increases the risk of cancer and mutation incidences. Measures should be taken to reduce the consumption of fish at risk in Huralazim wetland, thus minimizing the risk of gradual cancer or mutation.</span></span></span></span></span></span></span><br> &nbsp; Risk assessment, Transfer cyclic, Mesopotamichthys sharpeyi, Huralazim Wetland. 355 371 http://jifro.ir/browse.php?a_code=A-10-3597-1&slc_lang=en&sid=1 M.
