Abstract

Caspian kutum, Rutilus frisiiKamensky 1901, is a commercially important fish species in the southern part of the Caspian Sea. All of the metal entered in the Caspian Sea. The pollution of this metal cause To create environmental problem. To address the issue, some 51 R. frisii specimens were caught at five different fishing regions (including Astara, Anzali, Kiashahr,) of the southern shoreline of the Caspian Sea from September 2017 through January 2018. An inductively coupled plasma optical emission spectrometry (ICP-OES) was used to measure heavy metals concentrations in fish tissues. The highest concentrations of calcium, manganese in muscle tissue, aluminum, barium, cadmium, cobalt, iron, potassium, sodium, sulfur, tin, tungsten and zinc in kidney tissues, arsenic, nickel, lead and rubidium in gonads, chromium, lithium, Magnesium, phosphorus, antimony, silicon, strontium, thorium and titanium in skin tissue, copper and uranium in liver tissue. The lowest correlation between Ni and Sr with the other elements reported in liver tissue and the lowest correlation between Sb, Ni and Mn with another elements reported in liver tissue.
