Abstract
Multielement profiling analysis was carried out for the 100-m sediment core samples from Lake Baikal to elucidate the paleo-environment. The samples were decomposed by a fusion method using LiBO2, and major, minor, and trace elements were determined by ICP-AES and ICP-MS. About 50 kinds of elements were determined, and the vertical distributions of the elements obtained for the core samples showed some characteristic features.
