Concentrations of heavy metals(Hg, Pb, Cd, As, Ni, Cu, Zn and Mn) weremeasured in 130 healthy freshwater fish samples. The samples were digested using a
microwave system and heavy metal concentrations determined by inductively coupled
plasma mass spectrometry(ICP-MS) and a mercury analyzer. Respective limits of
detection(LOD) and limits of quantitation(LOQ) for each of the heavy metals were as
follows: Hg: 0.08 and 0.25 ng; Pb: 0.016 and 0.048 g/kg; Cd: 0.010 and 0.030 g/kg;
As: 0.014 and 0.042 g/kg; Ni: 0.052 and 0.158 g/kg; Cu: 0.085 and 0.258 g/kg; Zn:
0.310 and 0.939 g/kg; and Mn: 0.045 and 0.136 g/kg. Average concentrations of
heavy metals(with maximum and minimum values shown in brackets) in the freshwater
fish were: Hg: 0.057±0.056 (0.000~0.245) mg/kg; Pb: 0.096±0.123(0.010~0.984) mg/kg;
Cd: 0.004±0.004 (0.000~0.025) mg/kg; As: 0.277±0.225(0.028~1.433) mg/kg; Ni: 0.047±0.087
(0.008~0.802) mg/kg; Cu: 0.745±0.975(0.163？8.227) mg/kg; Zn: 19.330±13.547 (3.141~
107.045) mg/kg; and Mn: 1.918±2.746 (0.065~24.682) mg/kg. The weekly intake of Hg,
Pb, Cd, and As from freshwater fish were calculated to be 0.001？0.363%, comparable
to the provisional tolerable weekly intake(PTWI) established by the Joint FAO/WHO
Expert Committee for food safety evaluation.
