Three different types of tissue taken from three game birds such as Ring-necked Pheasant, Rufous Turtle Dove, Mallard and a mammal, Korean Water Deer were analyzed for five heavy metals such as iron, zinc. copper, lead and cadmium. The main purpose of this study was to make clear the background levels of the metal concentrations in the tissues of these game species. The metal levels were generally low and could be considered as the background levels. But some markedly high levels of lead were recorded in the muscles of birds shot by the shotgun. The implications of these results were discussed with respect to the health of people.
