Measurement of heavy metals in water, sediment and fish has always been a measure of environmental pollution and its impact on the human ecosystem. In this study, sampling was done from Khorramshahr fish market and sampling of Lutjanidae, Sciaenidae, Cynolossidae, Psettodidae, Stromateidae and shrimp muscle. According to the results, the concentration of Fe heavy metal was higher than all other metals in all studied samples. Concentration changes were observed for other heavy metals in fish muscle tissue and shrimp Metapenaeus affinis, respectively, Zn> Cu> Ni> Pb> Cd. The highest concentrations of Cd and Pb in salted and shelled fish with 0.19 and 0.24 µg / g and for Fe and Zn in salted fish were 14.14 and 8.42 µg / g, respectively. Metals were measured with concentrations of 20.9 and 9.98, respectively. Iron and zinc concentrations in shrimp were 32.13 and 15.18 µg / g, in nickel fish 0.29 µg / g and finally, the highest concentration of Pb was observed in shrimp fish with 0.24 µg / g. The highest amount of contamination was observed in shrimp and Fe metal with a concentration of 32.13 µg / g. Whereas, the least contamination was observed in white halva. The reason for this was that the cadmium content was lower than the detection range.
