Olkhon Island is the largest island in Lake Baikal and a part of Baikal National Park, Russia. The first objective of this study is to establish relationships between the particle size of accumulating sediments and their elemental composition, as well as the concentrations of heavy metals (Hg, Cd, As, Pb, Cr, Co, Ni, Cu, and Zn). The second goal is to completely assess the contamination level and to identify the possible sources of heavy metals using geochemical indices, including enrichment (EF) and contamination (C) factors, contamination degree (C), geoaccumulation index (I), and pollution load index (PLI).
