Abstract

The aim of the study was to determine Pb and Cd accumulation and to assess its trends in relation to age categories in feral pigeons from urban (Seoul) and industrial complex (Ansan) areas. This study shows that Pb and Cd concentrations in bone, kidney, liver, and lung increase with different developmental stages in feral pigeons. Particularly, Pb in the bones and Cd in the kidneys of birds were highly increased from chicks to adults. Mean Pb concentrations in pigeons from Seoul were three times higher in chicks than in eggs and six times greater in adults than in chicks. For Cd concentrations, pigeons in Seoul contained two times higher in chicks than in eggs and seventeen times higher in adults than in chicks. It indicates that Pb and Cd concentrations increase with age, and these are apparent to the results in Seoul than in the Ansan colony.

도심 지역인 서울시청 부근과 공단지역인 안산 반월 공단지역 내에 서식하는 비둘기의 알,새끼, 성조를 대상으로 각 발달 단계에 따른 납과 카드뮴의 체내 축적 농도를 비교하고 각 지역의 오염 수준을 파악하고자 수행하였다 조사 결과, 납 및 카드뮴 농도는 뼈, 신장, 간, 허파 등 모든 조직에서 새끼보다 어미가 높았으며,특히 납은 뼈에서, 카드뮴은 신장에서 현저하게 높았다. 서울의 경우, 납 농도는 알보다 새끼의 뼈 조직에서 약 3배 높았고, 새끼보다 성조의 뼈 조직에서 약 6배가 높게 검출되었다. 카드뮴의 경우에도 알보다 새끼의 신장 조직에서 약 2배, 새끼보다 성조의 신장 조직에서 약 17배정도 높게 검출되었다. 이와 같이 납과 카드뮴 농도는 모두 알, 새끼, 성조의 발달 진행에 따라 증가하는 경향을 보였으며, 이러한 경향은 안산 공단지역보다 서울지역이 더욱 현저하였다.
