This research was performed to detect the residual concentration of Cadmium in parts of cattle to find the different levels of Cadmium accumulation as regions. The samples are taken from flank meats, rib meats. kidneys, and livers of the ten randomly chosen cattle at slaughterhouse in Kyunggi-do. All samples and standard solution were prepared by the wet-ashing digestion. The digested samples were determined with Flame Atomic Absorption Spectrophotometer (F-AAS).
The results are followings:
1. The Cadmium residual concentrations were not detected from the flank meat of the first. sixth, seventh and eighth cattle: however, 0.513 ppm Cadmium residual concentration was detected from the flank meat of the fifth cattle.
2. While the Cadmium residual concentrations were not detected from the rib meat of the first, third, fourth, fifth and seventh cattle, 0.284 ppm was detected from the second cattle and 0.245 ppm was from the tenth cattle.
3. The highest Cadmium residual concentrations, 0.724 ppm, were detected from the kidney of the fifth cattle. The fourth cattle showed 0.716 ppm Cadmium residual concentration, sixth cattle had 0.673 ppm, and third cattle had 0.666 ppm. The Cadmium residual concentration was not detected from only seventh cattle. According to these, Cadmium accumulation of cattle’s kidney is significantly higher than any other regions of cattle.
4. Cadmium residual concentrations were detected from every tested cattle’s liver sample. Especially, the fifth cattle showed 0.426 ppm and ninth cattle had 0.405 ppm. These concentrations were significantly higher than other cattle’s concentration rankle. 0.145 ppm~0.278 ppm.
5. Comparing of the Cadmium residual concentration between cattle’s kidney and liver, the kidney showed notably higher concentration, 0.45±0.26(mean±SD) ppm, than liver’s concentration, 0.26±0.10(mean±SD) ppm.
6. Comparing all the section tested, each of the average Cadmium residual concentrations are followings: cattle’s kidney had 0.45±0.26(mean±SD) ppm which is the highest concentration, then liver had 0.26±0.10(mean±SD) ppm, flank meat had 0.17±0.19(mean±SD) ppm. The rib meat of cattle showed the lowest Cadmium residual concentration, 0.09±0.11(mean±SD) ppm.
