Abstract

In order to examine and compare Lead metal accumulation levels in muscle tissues of Brachirusorientalis, sampling fish was done in both Bushehr and Asalouyeh stations during the summer 2013. After biometry of the samples, muscle tissues were separated and chemical digestion was done. Lead accumulation levels in tissues were measured by using a graphic furnace atomic absorption instrument. acdia_f0 Based on the obtained results, mean Lead concentrations in muscle tissues were 1.459 ± 0.747 mgkg-1dw in Bushehr station and 3.166 ± 2.447 mgkg-1dw in Asalouyeh station, and no statistically significant differences were observed between the two stations (P=0.055). Based on the obtained concentrations and analysis done it was specified that according to WHO, FAO, ITS, and Turkish Guidelines standards, the amount of Lead metal in muscles of Brachirusorientalis was higher than the permissible standard levels in both study stations and it can be concluded that using this species in these regions are rather dangerous and it will naturally have bad effects on the consumers of these products and necessary care should be taken to use it in the food meals.
