سنجش ميزان تجمع نيكل در ميگوي سفيد هندي(Penaeus indicus) درآبهاي ساحلي جاسك

Nickel concentration in Penaeus indicus from Jask coastal waters, Persian Gulf

The investigation to assess the metal-accumulating ability of the shrimp (Penaeus indicus ), the concentrations of Nickel (Ni) were investigated in 2008. Shrimp were seasonally (autumn and winter) collected from the Jask coastal area, located in East Hormozgan. The samples of shrimp were collected and washed with seawater and dried it with the help of freeze dryer and digested using a microwave digester in a super-pure nitric acid solution. The Nickel determined with Atomic Absorption Spectrometers (AAS). The recorded result, the mean Nickel concentration of male and female in autumn and winter were (0.007-0.084) and (0.007-0.087) µg/g of dry weight respectively. No significant differences in shrimp (male and female) and seasonally (autumn and winter) concentrations were detected. (SPSS, t-test , p > 0.05)
