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

Authors

Abstract

We assessed the metal-accumulating ability of the shrimp Penaeus indicus for Nickel (Ni)
in 2008. Shrimps were seasonally (autumn and winter) collected from Jask coastal area, East
of Hormuzgan province in the Persian Gulf. The samples were washed with seawater and
dried with the help of freeze dryer and digested using a microwave digester in a super-pure
nitric acid solution. The Nickel concentration was determined with Atomic Absorption
Spectrometers (AAS). The result showed the mean Nickel concentration of male and female
in autumn and winter were 0.007-0.084 and 0.007-0.087μg/g of dry weight, respectively. No
significant differences in concentrations of Nickel in shrimps (male and female) and seasons
(autumn and winter) were detected (P>0.05).
