Abstract
- The population of river otter(Lutra lutra) has been declined most of the world due tohunting, habitat destruction and indirect or direct influences of eutrophication, acidification andtoxic chemicals. This study is conducted to identify the population decline of river otter in Koreawith relation to environmental pollution caused by accumulation of heavy and traced metals. The~ Dec, 2004 at a monthly basis by collecting spraints. Atotal of 228 spraints were collected and analysis was done by ICP-AES. The concentrations offourteen metals (Cr, Zn, Cd, Pb, Ni, Fe, Co, Mn, Mg, Cu, Al, Ba Hg, As) have been determined.Annual concentrations of Cd (1.38g g-1), Zn (599.06g g-1), Pb (5.54g g-1) at Gucheon werehigher than those of Yeonchocheon. Concentrations of Cr (5.01g g-1), Ni (1.91g g-1), Co (0.25g g-1) were higher at Yeonchocheon. Most metals in winter were significantly increased(P0.05) as season progressed from spring to winter. Pb (15.58g g-1), Cu (15.15g g-1) atGuchoen and Cr(5.77g g-1) at Yeonchocheon were high in the downstream of winter.
