독도 주변 해역 주상퇴적물의 중금속 분포

Abstract

The vertical distribution of heavy metals were investigated for the sediment cores(2 sites) in the adjacent sea to the Dokdo in November∼December 2006. The maximum values for Al, Fe, Ma, Cr, Co, Ni, Cu, Zn, As Cd, Pb and Hg of total samples were 9.44%, 5.15%, 13,956ppm, 88.1ppm, 29.9ppm, 59.1ppm, 51.2ppm, 158ppm, 27.8ppm, 0.60ppm, 47.8ppm and 0.10ppm. The maximum values of Mn, Co, As, Pb and Hg were observed at the upper layer(0∼3cm) of each sediment core. However, the profiles of Cu, Zn, Cd showed an decreasing trend toward the upper layer.s were 9.44%, 5.15%, 13,956ppm, 88.1ppm, 29.9ppm, 59.1ppm, 51.2ppm, 158ppm, 27.8ppm, 0.60ppm, 47.8ppm and 0.10ppm.
