Abstract :

The purpose of this study is to investigate the native fish of Hamri, Shirbat and Tilapila in Shavor River in Shush city in terms of heavy metal contamination and risk assessment for consumers. To investigate the amount of heavy metals remaining in fish meat) were collected from several parts of Shavor River in Shush city. The results obtained from the descriptive statistics of the residual amount of elements in Shirbat, Hamri and Tilapila species of fish did not have a significant relationship with the amount of cobalt, copper, nickel and zinc residual heavy metals in fish meat with international health standards, it showed that the concentration of all elements Except for lead and nickel, they were significantly (p<0.05) below the permissible limit. The concentration of lead was significantly (p<0.05) higher than the permissible limit. The health risk assessment showed that according to the maximum tolerable daily intake (MTDI) of heavy metals, the daily and continuous consumption of these products by different age groups (children and adults) of consumers is completely safe, except for lead, and there is no risk of this there are no comments for them. The results of this research showed that the average concentration of arsenic, cadmium, cobalt, chromium, copper, iron, mercury, manganese, molybdenum, nickel, tin and zinc in Shirbat, Hamri and Tilapila fishes is lower than the international standards and only Pb concentrations were higher compared to FAO/WHO. Also, the estimation of daily intake and according to the MTDI values of all metals except lead showed that the consumption of Shirbat, Hamri and Tilapila fish currently does not pose a risk to human health, however, to prevent possible contamination in the future In terms of management, more attention should be paid to these pollutants and their possible sources.
