KANDUNGAN LOGAM Cd, Cu, Pb DAN Zn PADA IKAN GULAMA (Sciaena russelli) DARI PERAIRAN DUMAI, RIAU: AMANKAH UNTUK DIKONSUMSI?
Abstract: Determination of
four heavy metals (Cd, Cu, Pb and Zn) concentration in muscles andbones of
edible croacker fish Sciaena russelli collected from Dumai coastal waters
withtwo different anthropogenic activities has been carried out. Heavy metal
concentrationswere 0.13, 0.21, 2.31, 6.38 and 0.29, 0.37, 5.05, 8.45 μg/g d.w
in muscles and bones forCd, Cu, Pb and Zn, respectively. Fish collected from
the station with more anthropogenicactivities accumulated more metals in both
their muscles and bones than those from lessanthropogenic activities. Negative
correlations between metal concentrations and the sizesof fish (length and
weight) were observed. Concentrations of all metals in smaller sizes offishes
were higher than those in larger sizes and all metals were found to be higher
inbones. In general, the concentrations of analyzed metals were still below
PTWI and thestandard limit for consumption of seafood established by FAO/WHO.
Therefore, theconcentrations of heavy metals in croacker fish from Dumai
coastal waters can beconsidered as safe and accordingly there is no risk for
the human consumption of this fishspecies.
