Abstract
This study aimed to determine the concentrations of heavy metals (Cd, Cr, Pb, Zn, Fe, and Cu) in gills, muscles, kidney, bone, liver, and reproductive organs of Notopterus notopterus from the Sail River. The results shown that the concentrations of heavy metals in each tissues of fish were as follow: muscles > reproductive organs > liver > kidney > gills and bone for Cd; liver > bone > kidney > muscles > reproductive organs > gills for Cr; gills > kidney > bone > muscles > liver > reproductive organs for Pb; gills > bone > reproductive organs > kidney > liver > muscles for Zn; gills > muscles > liver > kidney > reproductive organs > bone for Fe; bone > liver > kidney > muscles > gills > reproductive organs for Cu. Concentrations of Cr (95.62 mg/kg) was highest than 5 others heavy metals. The average of metal concentrations of Pb (35.62 mg/kg), Zn (88.47 mg/kg), and Fe (2.35 mg/kg) were highest in the gills. The estimated concentrations of Cd, Cr, Pb, Fe were higher and Zn, Cu were lower than the limits permitted.
