ABSTRACT
This study was conducted to evaluate the heavy metal content (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) of forest soil and of Lonicera japonica and to understand the correlation in contents of heavy metal between forest soil and L. japonica near the Onsan industrial region. The content of As, Cd, Cu, Pb and Zn was higher in the industrial region than in forest regions, but re, Mn and Ni content was higher in forest regions than in the industrial region. Among heavy metals, the content of Cd, Cu, Pb and Zn in leaf, stem and root of L. japonica growing near industrial regions was significantly higher (p<0.05) than in forest regions. The content of As, Cd, Cu, Pb and Zn in L. japonica tissues showed a positive or negative correlation with those in forest soils. Correlation coefficients of Cu content between forest soil and organs of L. japonica ranged from 0.93 to 0.99 (p<0.01). It was concluded that L. japanica could be used in heavy metal (Cd, Cu, Pb, and Zn) decontamination of forest soils of industrial regions.

적요

본 연구는 온산 공단지역 산림토양과 그곳에 우점하고 있는 인동덩굴의 기관별 중금속(As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) 함량을 분석하고 산림토양과 식물체간 중금속 함량의 상관관계를 규명하여 덩굴식물인 인동덩굴을 중금속 오염지의 토양 정화 및 식생복원에 대한 기초 자료를 제공하는데 목적이 있다. 토양중금속 중 As, Cd, Cu, Pb, Zn은 공단지역이 산림지역보다 유의적으로 높은 함량을 나타낸 반면 Fe, Mn 및 Ni 함량은 산림지역이 공단지역보다 유의적으로 높은 것으로 나타났다. 중금속 중 Cd, Cu, Pb과 Zn은 인동덩굴의 잎, 줄기, 뿌리에 있어서 공단지역에서 자라는 식물체의 함량이 산림지역의 함량보다 유의적으로 높은 것으로 나타났다. 산림토양의 As, Cd, Cu, Pb, Zn 함량과 인동덩굴 기관별 함량은 높은 정의 혹은 부의 상관을 보여주었으며, Cu가 산림토양과 인동덩굴의 기관 간에 0.93~0.99의 가장 높은 상관계수를 나타내었다. 인동덩굴 식물체의 기관 내 높은 중금속 함량과 산림토양과의 높은 상관계수를 고려하면, 인동덩굴은 공단지역과 같이 중금속(특히 Cd, Cu, Pb와 Zn)에 오염된 산림토양에서 정화식물로 이용할 수 있을 것으로 판단된다.
