Abstract

Backgrounds& Objectives: Nowadays, the entry of effluents containing Heavy metals, which are mostly the result of industrial activities, into the ecosystem of aquatic organisms and, consequently, the accumulation of these metals in the body of aquatic animals is a major concern which is aquatic life and biodiversity of aquatic ecosystems affects. The Caspian Sea is one of the most important aquatic ecosystems that the entry of various pollutants has caused serious damage to these ecosystems. The Caspian Seal, the only mammal in the Caspian Sea, is endangered. The aim of this study was to measure Cadmium in some Caspian Seal tissues on the southeastern shores of the Caspian Sea. Method: In the present study, ten corpses of Caspian Seals were collected and inseminated from the coast of the Caspian Sea. Liver, kidney and fat samples were digested to measure Cadmium content. The concentration of Cadmium was measured by a mass spectrometer machine. Findings: The highest concentration of Cadmium in kidney tissues was 13. 59± 0. 73 μ g / kg which higher than the liver with mean of 1. 6± 0. 16 μ g / kg and greater than mean of 0. 07± 0. 02 fat. The concentration of Cadmium in male and female tissues was investigated and there was no significant relationship between Cadmium metal concentration and sex of seals. The presence of significant amounts of Cadmium in 90% of the samples shows the high Pollution of the Caspian Sea with Heavy metals, including Cadmium metal, which is even toxic at very low levels. Discussion and Conclusion: Considering the significant decrease in the population of the Caspian Seals in recent years and the persistence of Heavy metals, the use of these toxic metals in the industry has to be reduced, as well as the sources of the input of these pollutants to the Caspian Sea to prevent the entry of these toxic metals into the Caspian Sea or before filtration proceed. This will reduce the Pollution of the Caspian Sea and helps the health of the aquatic environment.
