Introduction: Bioaccumulation Capacity of Heavy metals in aquatic bodies can do a serious threat to food security and public health. Therefore, in this study, the amount of lead, cadmium and copper in edible tissues of hydrothermal fish in Alborz province was determined in 2017.
Materials and Methods: Twenty-one carp fish of three species were randomly selected from the Mahmoudi fishery, which supplies the Alborz hydrothermal fish market, and after acidic digestion of the specimens, the concentration of lead, cadmium and copper was determined by Atomic absorption device.
Results: The mean concentration of lead, cadmium and copper in wild carp, amur and phytophagus in ppb and for cadmium was measured. Highest amount of lead in Hypophthalmichthys molitrix, Cadmium in Ctenopharyngodon idella &Copper in Hypophthalmichthys molitrix was observed.
Statistical comparison of the mean concentrations of the Heavy metals with the guidelines of the United Nations Food and Agriculture Organization showed that the mean concentration of all Heavy metals was lower than the permissible limit.
Discussion: Although currently the mean concentrations of the evaluated Heavy metals in the carp edible tissue of Alborz province are not exceeded, but lack of proper management of the water supply resources of fish ponds can lead to the entry of pollutants, including heavy metals, into the fish farm.In resident aquaculture tissues, endangering the health of consumers. |
