概要	To evaluate the sanitary environment for the public, we set up a narrow area facing the Gulf of Hiroshima, captured and measured the concentrations of Cd and Zn in their kidneys as well as in the soil inhabited. The 6 wild boars whose ages were estimated less than 3 years contained 1.07±0.70 mg/kg of Cd, while the 5 raccoon dogs showed varied concentrations of Cd age-dependently from 0.29 to 20.60 mg/kg. Despite the low Cd in the soil, the wildlife concentrated high Cd internally. We speculated the oyster shell as one of the candidates of the source of Cd for wildlife in the non-polluted area. Measurements of Cd and Zn at the Gulf of Hiroshima, Okayama or Kagoshima, the oysters indicated the accumulation of Cd in their shells with the values of 0.16 ~ 0.20 mg/kg, no matter how the concentrations of Cd in the soil varied. This evidence could partly support the possibility for the wildlife to accumulate excess amount of Cd to eat crops given such fertilizers.
