한국산 야생 청둥오리의 카드뮴(Cd)과 납(Pb) 오염 = Cadmium and Lead Accumulation of Wild Mallard in Korea

국문 초록 (Abstract)

조류는 서식지와 식성이 다양하여, 환경오염의 지표 생물로서 중금속 오염 모니터링에 이용되고 있다. 본 연구는 야생 청둥오리를 대상으로 독성원소인 카드뮴(Cd)과 납(Pb)의 조직 축적농도를 파악하고 환경오염 모니터링의 위한 기초자료를 제공하고자 하였다. 분석결과 청둥오리에서 카드뮴(Cd) 평균농도는 신장(1.19㎍/g)과 간(0.37㎍/g)에서 높고, 뼈(0.11㎍/g)와 근육(1.17㎍/g)에서 낮게 나타났다. 납(Pb)은 신장(1.01㎍/g)과 뼈(0.6㎍/g)에서 높고, 근육(0.2㎍/g)과 간(0.3㎍/g)에서 낮았다. 본 연구에서 청둥오리의 카드뮴(Cd)과 납(Pb)의 농도는 모두 비오염수준으로 간에서 카드뮴(Cd) 3㎍/g 이하, 신장에서 카드뮴(Cd) 8㎍/g 이하, 간에서 납(Pb) 3㎍/g 이하에 해당하는 것으로 나타났다.

Birds are used for the heavy metal contamination monitoring as the indicator of the environmental contamination because of their various habitat and food habit. This study focused on Cd and Pb concentrations and their tissue distributions of wild mallards (Anas platyrhynchos) to provide reference data in the environmental monitoring of heavy metals. In wild mallard, mean Cd concentration was high in kidney (1.19㎍/g) and liver (0.37㎍/g), and low in bone (0.11㎍/g) and muscle (1.17㎍/g). The mean concentration of Pb was high in kidney (1.01㎍/g) and bone (0.6㎍/g), and low in muscle (0.2㎍/g) and liver (0.3㎍/g). In this study, the concentrations of Cd and Pb were at background level showing ＜3㎍/g in liver Cd, ＜8㎍/g in kidney Cd and ＜6 ㎍/g in liver Pb.
