영어 초록
We measured the grain size and metallics elements (Li, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Hg, Pb, Fe and As) of surface sediments collected from 27 sampling sites in the Abalone aquaculture. The concentration range and average value of metallics elements were also below the sediment quality guidelines (TEL). As the pollution level was estimated by using enrichment factor (Ef) and index of geoaccumulation (Igeo), the enrichment factor (Ef) was about 1 for most of metallic elements were smaller than 1. However Arsenic (As) had highest value of 2.35. Index of geoaccumulation (Igeo) for the metallic elements (As, Pb and Mn) were ranged Igeo-class 0 (practically unpolluted) and most metallics elements (Li, V, Cr, Fe, Co, Ni, Cu, Zn, Cd, Hg and Fe) were ranged Igeo-class 0~2, indicating that the pollution levels of metallic elements should not be significant. It is necessary to keep monitoring pollution level in Abalone aquaculture to conserve the blue belt.
