Abstract

The Korean water deer (Hydropotes inermis argyropus) is an endemic species and one of the common species in Korea. The species ranges throughout the Korean peninsula and plays an important role as herbivores in natural ecosystem. Therefore, the species could be used as a good bio-indicator to monitor the quality of habitats. This study was to estimate the concentrations of five heavy metals (Fe, Cu, Zn, Cd and Pb) from three different organs (kidney, liver and spleen) in the Korean water deer. According to the analyses of heavy metal accumulations, the concentration of Fe is higher than Cu, Zn, Cd and Pb from all the organs. Among the organs, spleen (286.50) showed higher heavy metal concentrations than kidney (39.40) and liver ($23.21\;{\mu}g\;g^{-1}$). In general, the concentrations of the heavy metals were about two times higher in Cheorwon, Gangwon province than in the Eastern part of Jeonnam province. In particular, Cd and Pb showed a significant difference (P<0.05). Except for Fe in spleen, all of the heavy metal concentrations were below background levels.

한국고라니(Hydropotes inermis argyropus)는 우리나라의 고유종으로 가장 흔한 종의 하나이다. 이 종은 한반도 전역에 널리 분포하며 자연생태계에서 초식자로서 중요한 역할을 하는 것으로 알려져 있다. 따라서 고라니는 서식지의 질을 모니터링하는데 하나의 좋은 생물지표종으로 이용될 수 있을 것이다. 이 연구에서는 강원도 철원지역과 전라남도 동부지역에서 수집된 한국고라니의 서로 다른 3가지 조직(신장, 간, 지라)에서 5가지 중금속(Fe, Cu, Zn, Cd, Pb)의 농도를 측정하였다. 중금속 농도의 분석에 따르면, 철의 농도는 구리, 아연, 카드뮴, 납에 비해 모든 조직에서 높게 나타났다. 이중, 지라(286.50)가 신장(39.40)과 간($23.21\;{\mu}g\;g^{-1}$)에 비해 높은 중금속 축적을 보였다. 일반적으로, 중금속의 농도는 전남 동부지역에 비해 강원도 철원지역에서 조금 높게 나타났다. 특히, 카드뮴과 납의 경우 매우 유의한 차이를 보였다(P<0.05). 이러한 중금속의 농도는 지라의 철을 제외하고는 모두 백그라운드 수준(background level) 내로 낮게 나타났다.
