摘要

No accumulation of heavy metals was revealed in the deep (7.5m) central zone of a eutrophic peatbog. Ti and W are the msot dispersed elements in the peat depsit; Fe, Mo, and Mn are the most accumulated elements. The distribution of heavy metals during peat genesis dpeneds on the quality of sorption humus barriers and the redox zonality of the peat deposit and, hence, is indicative of the redox stages of bog evolution. Mo is a universal indicator element; its distribution in the peat profile clearly differentiates the redox conditions in both oxidative and reductive environments.
