Abstract
In order to determine the levels of trace elements in livestock products surveys have been conducted in Inchon area. The samples were obtained from cattle organs, swine organs, chicken organs, eggs and milk. The levels of nine harmful trace elements(As, Cd, Cr, Cu, Fe, Hg, Mn, Pb, Zn) and three trace elements(Ca, Co, Na) were determined by ICP spectrometry, 1. In the survey on 9 harmful metals with 20 cattle, the highest level was 56.90ppm(Fe, liver) and the lowest level was 0.10ppm (Cd, muscle). 2. In the survey on 9 harmful metals with 31 swine, the highest level was 169.71ppm(Fe, lung) and the lowest level was 0.02ppm(Cd, heart). 3. In the survey on 9 harmful metals with 20 chickens, the highest level was 42.64ppm(Fe, liver) and the lowest level was 0.00ppm (Hg, entire organs). 4. In the survey on 9 harmful metals with 23 eggs, the highest level was 26.08ppm(Fe, yolk) and the lowest level was 0.00ppm (Hg, yolk and white). 5. In the survey on 9 harmful metals with 20 cases of milk, the highest level was 6.02ppm(Zn) and the lowest level was 0.04ppm(Cd). 6. In cattle the mean concentrations were highest in seven elements and in milk the mean concentrations were lowest in five elements.
