Abstract

This review paper was written to provide background information as well as future application for aquatic ecologists interested in using stable isotope. Stable isotope techniques has proved to be an extremely useful to elucidate a lot of environmental and ecological problems. Stable isotopes have been used as possible tracers to identify sources, to quantify relative inputs in a system. When utilized carefully, stable isotope tools provides apparent advantages for the scientists to find out the processes of material cycles in various environments and energy flows in natural ecosystems.

안정동위원소 분석기법(SIA)은 생태학 및 환경학적 측면에서 유기물의 기원 추적 및 생지화학적인 문제를 해결함에 있어서 유용하기 때문에 그 사용이 꾸준히 증가되고 있다. C, N, S, H, O 등의 원소는 모두 하나 이상의 동위원소를 가지고 있으며, 동위원소 조성비는 질량분석기를 이용하여 매우 정밀하게 측정할 수 있다. 이러한 동위원소 조성비는 물리적, 화학적, 생물학적 반응을 통한 분별작용으로 인하여 예측 가능한 방식으로 변경된다. 더 나아가 안정동위원소 기법은 생태와 환경 학문에서 유기물의 기원을 밝히고, 생태계내 먹이망 구조를 밝히고, 영양염 등의 질산염 순환을 이해하고, 동물의 이동경로를 밝히고, 오염원을 추적하는 등 매우 강력한 도구로서 사용할 수 있다. 그러므로 생태학 및 환경학 분야에서 안정동위원소의 활용이 매우 유용하다.
