Heavy metal contents in the various organs of dogs raised in the urban area and the rural area were determined. The heavy metal contents such as cadmium, copper, zinc and chromium in the organs of the dogs raised in the urban area were remarkably higher than those in the organs of the dogs raised in the rural area. These results strongly indicate that there is a possibility that the human organs of urban inhabitants are also contaminated with the heavy metals.
