Abstract

The heavy metal contents accumulated in the birds organ were analyzed by use of 10 species of birds to investigate the environmental pollution of the birds inhabited in Mt. Chiri. Heavy metal concentrations in bird organs, e.g. muscle, liver, kidney, lung and heart were analyzed for 10 species of the birds. 1. Contents of some heavy metal elements such as Fe, Zn, Cu and Mn were similar level compared with any other district. But contents of some heavy metal elements shch as Pb, Cd and Hg were comparatively lower level than those in any other district. 2. The contents of heavy metal accumulation in the muscle of the bird organs were detected much more from the migrants than the resident birds ; the resident bird, Phasianus colchicus were detected to contain $0.01{\mu}g/g$ og Hg and $0.05{\mu}g/g$ of Cd, but in the migrant bird, Turdus dauma they were detected to contain $0.17{\mu}g/g$ of Hg and $0.08{\mu}g/g$ of Cd. 3. The contents of lead were scarcely detected in the muscle of 10 species of birds, but it was highly detected from the hunting (meat-eating) birds such as Phasianus colchicus ($0.17{\mu}g/g$) and Streptopelia orientalis ($0.11{\mu}g/g$). Generally, the concentration of heavy metals of the analyzed birds was more mercury than Cadmium.

환경오염(環境汚染) 관계(關係)를 구명(究明)하기 위(爲)하여 지리산(智異山) 지역내(地域內)에서 서식(棲息)하고 있는 꿩과 멧비둘기, 직박구리, 호랑지빠귀, 흰배지빠귀, 박새, 물까치, 까마귀, 큰부리까마귀, 참새 등(等) 10종(種)의 성조(成鳥)에 대한 각(各) 조직기관별(組織器官別) 중금속(重金屬)의 농도(濃度)를 분석(分析)하였던 바 그 결과(結果)는 다음과 같다. 1. 채집(採集)한 10종(種)의 조류(鳥類)에 대한 중금속(重金屬)의 축적농도(蓄積濃度)는 Fe, Zn, Cu, Mn 등(等)의 필수원소(必須元素)는 타지역(他地域)과 비슷한 수준(水準)이었으나 Pb, Cd, Hg, 등(等)과 같은 오염원소(汚染元素)는 대체(大體)로 낮은 경향(傾向)이었다. 2. 텃새인 꿩의 근육(筋肉)에서의 Hg는 $0.01{\mu}g/g$, Cd는 $0.05{\mu}g/g$로서 낮게 검출(檢出)된데 비(比)하여 여름새인 호랑지빠귀의 근육(筋肉)에서의 Hg는 $0.17{\mu}g/g$ Cd는 $0.08{\mu}g/g$로서 높게 검출(檢出)되었다. 3. 연(鉛)(Pb)은 근육(筋肉)에서는 거의 검출(檢出)되지 않았지만 수렵조류(狩獵鳥類)인 꿩과 멧비둘기에서$0.11{\mu}g/g{\sim}0.17{\mu}g/g$이 검출(檢出)되었고 대체(大體)로 카드뮴(Cd)에 의(依)한 오염(汚染)보다는 수은(水銀)(Hg)의 오염(汚染)에 편중(偏重)되어 있는 경향(傾向)이었다.
