Abstract
The aim of investigation is about the accumulation of heavy metals (Mercury, Lead and Cadmium) in muscle, liver and brain tissues in Neogobius melanostomus from the coast of the Caspian Sea. This research was carried out in 15 samplesduring the year 2015- 2016.Sampling stations were in Sari, Babolsar, Fereydoon kenar, Royan and Ramsar. In order to determine the concentration of heavy metals, Atomic Absorption (A.A.S) and mercury analyzer DMA-80 were used. Cd concentration results in liver 0.33± 0.15and in muscle0.28±0.10 and in brain 0/19±0/05 mg/kg wet weight, Average Pb concentration in the liver was 9.41±1.01 and in muscle10.5±1.89 and in the brain was about 2.18±7 mg/kg wet weight, Average Hg concentration in the liver at various stations was43.10±10.30 and in muscle85.05 ±33.10 and in brain8.24 ±3.07 ug / kg wet net weight.One way ANOVA showed that there was no significant difference between the concentration of mercury in brain tissue and lead in muscle tissue in different stations (p>0.05 ). Pearson correlation coefficient showed that there was a reverse correlation between Cd concentration in liver and muscle tissues and the standard length. The highest accumulation of mercury was observed in muscle tissue and the lowest was in brain tissue. The concentration of lead and cadmium in the target tissues were lower than the standard levels and the concentration of mercury was higher than the WHO1/FAO2 / NHMRC3 / MAFF (UK) 4 standard limits.Person analysis showed, heavy metal (lead, cadmium) in the muscle of "Neogobius melanostomus" was higher and mercury metal was lower than standard WHO1/FAO2 / NHMRC3 / MAFF (UK) 4.
