This study was performed to investigated the contamination levels of harmful heavy metals were sampled from Aug. 1 to Aug. 31, 1997, at 9 areas in Cheonbuk area. The heavy metal contents were determinated by ICPS(Inductively Coupled Plasma Spectrometer) method. The levels of total lead, cadmium, aluminum, iron and copper were determined and the results were summarized as follows: The minimum and maximum values(ppm) of 9 areas of Carassius auratus were Pb: 2.03~6.19, Cd: 0.06~ 0.76, Al: 8.84~23.5, Zn: 10.68~48.71, Cu: 0.60~1.51ppm. Among the five heavy metals contents, the highest was zinc and the lowest was cadmium. The results showed that the contents of Pb, Cd, Al, Zn and Cu in Carassius auratus were lower than the FAO/WHO maximum allowance.
