Abstract

Vertical distribution of ash, Pb, Cd, Zn, Fe, Mn, Cu, Al, Ca, Mg in oligotrophic bog „Zhuravlyne” (Skolivski Beskydy, Ukrainian Carpathians) was investigated. Vertical cores were sampled in 2006 and dated by 14 C method. Distribution of ash in peat slices increased considerably closer to the bog surface. Reasonable agreement exists in the comparison between the ash distribution and measurements of Al and Fe concentrations, what point to a decisive influence of aluminosilicate material formed from the rocks weathering on ash deposits. Historical trends of heavy metals levels in peat based on the absolute concentrations or their ratio to Al are identical and concomitant with the history of industrial development of Western Europe. Keywords: ombrotrophic peat bogs, heavy metals, Ukrainian Carpathians.

Highlights

Ombrotrophic peat bogs as a good paleobotanical object due to their geochemical peculiarities of development, due their ability to capture trace elements from atmosphere and possibility to date peat layers, are widely used for the study and reconstruction of the past years geochemical background since the 90s of last century [18]
Analysis of the chemical elements distribution in different layers of oligotrophic peat mires allow to determine 1) the natural intensity of atmospheric precipitation of chemical elements, 2) the influence of anthropogenic factors on the precipitation process, 3) the level of air pollution compared to the previous natural geochemical background
The original purpose of the project was to estimate the historical trends of chemical elements and ash in the Zhuravlyne peat bog

Summary

Introduction

Ombrotrophic peat bogs as a good paleobotanical object due to their geochemical peculiarities of development, due their ability to capture trace elements from atmosphere and possibility to date peat layers, are widely used for the study and reconstruction of the past years geochemical background since the 90s of last century [18]. Such locations are useful for identifying regional background of the natural environment and its changes under the human activities for the present, and in retrospect
