摘要Objective: To determine Fe, Cu, Zn, Pb and Cd concentrations in muscle of sind sardinella [Sardinella sindensis (S. sindensis)] from Balochistan coast, Pakistan. Methods: S. sindensis were collected from Balochistan coast, Pakistan, at autumn inter monsoon, north east monsoon, spring inter monsoon and south west monsoon during October 2005-September 2006. All samples were analyzed for Fe, Cu, Zn, Pb and Cd by AAnalyst 700 flame atomic absorption spectrophotometer. Results: Generally, S. sindensis caught from Balochistan coast showed the accumulation level of Fe [(16.88 ± 5.60) μg/g], Cu [(2.74 ± 1.89) μg/g], Cd [(0.29 ± 0.25) μg/g], Zn [(4.29 ± 2.31) μg/g] and Pb [(0.24 ± 0.24) μg/g] in the muscle tissues. Conclusions: The metal concentrations in fish from Balochistan coast observed in this study were lower than the limit values. Therefore, all metal accumulations in S. sindensis have to be monitored continuously, especially in this region.
