  • The heavy metal contents in Carassius auratus, that were sampled from Nov.1 to Nov. 31, 1991 at 6 areas in Joenlabuk-do. The mercury contents was determined by mercury analyzer using the combustion Goldamal-gamation method. The arsenic contents were determined by spectrophotometry using silver diethyl ditiho carbamate method. The contents of other heavy metals were determined by inductively coupled plasma spectrometer method. The levels of total mercury, arsenic, cadmium, lead, cupper, manganes, and zinc were determined and the results were summarized as follows : The 6 areas over all range(ppm) were Hg : 0.0167~0.0407, As : N.D.~0.0018, Cd : 0.1256~0.1935, Pb : 0.3536~0.6593, Cu : 0.2094~0.3792, Mn : 2.9059~6.9335, Zn : 14.3095~48.1615ppm. Among the seven heavy metals contents, the higest was zinc and the lowest was arsenic. The results show that contents of Hg As, Cd, Pb, Mn and Zn in Carassius auratus were lower than the FAO/WHO maximum allowance.
