History of Atmospheric Lead Deposition Since 12,370 14C yr BP from a Peat Bog, Jura Mountains, Switzerland
William Shotyk,Dominik J. Weiss,Peter G. Appleby,A. Cheburkin,Robert Frei,M. Gloor,Jan Kramers,S. Reese,W.O. van der Knaap +8 more
TL;DR: A continuous record of atmospheric lead since 12,370 carbon-14 years before the present (14C yr BP) is preserved in a Swiss peat bog, indicating the beginning of lead pollution from mining and smelting, and anthropogenic sources have dominated lead emissions ever since.

Mercury in a spanish peat bog: archive of climate change and atmospheric metal deposition
Antonio Martínez-Cortizas,Xabier Pontevedra-Pombal,E. García-Rodeja,Juan Carlos Nóvoa-Muñoz,William Shotyk +4 more
TL;DR: A peat core from a bog in northwest Spain provides a record of the net accumulation of atmospheric mercury since 4000 radiocarbon years before the present and implies that the thermal lability of the accumulated mercury can be used not only to quantify the effects of human activity, but also as a new tool for quantitative paleotemperature reconstruction.

Interdependence of peat and vegetation in a tropical peat swamp forest
TL;DR: Details are presented of forest structure and tree composition of the principal peat swamp forest types in the upper catchment of Sungai Sebangau, Central Kalimantan, Indonesia, in relation to thickness and hydrology of the peat.

Critical examination of trace element enrichments and depletions in soils: As, Cr, Cu, Ni, Pb, and Zn in Swiss forest soils.
TL;DR: In this article, the authors present an overview of trace element concentrations in Swiss forest soils and to critically assess the measured values with respect to anthropogenic input vs. lithogenic background.
