    Using flame atomic absorption spectrophotometer (FAAS), concentration of toxic metals Pb, Cd, Cr, Cu, Fe, Mn and Zn in two Jahangirnagar University lakes were determined. For Lake-1, concentration ranged as 0.021 to 0.031 mg/l for Pb, 0.6 to 1.029 mg/l for Fe, 0.006 to 0.09 mg/l for Mn and 0.0042 to 0.0069 mg/l for Zn. For Lake-2, concentration ranged as 0.028 to 0.032 mg/l for Pb, 0.593 to 0.682 mg/l for Fe, 0.069 to 0.116 mg/l for Mn and 0.0019 to 0.004 mg/l for Zn. Cd, Cr and Cu were found below the detection limit both in Lake-1 and Lake-2. For Lake-1, the observed pH and TDS ranges 7.33-7.37 and 126-156 mg/l respectively. For Lake-2, the observed pH and TDs ranges as 7.31-7.37 and 129-152 mg/l respectively. Insignificant correlation was found among the heavy metals in Lake-1. For Lake-2, Pb and Mn show significant positive correlations among themselves and.. Read More»
