History of the Pollution in Tomsk Region (Siberia, Russia) According to the Study of High-Moor Peat Formations
Atmosphere Pollution High-Moor Peat Trace Elements in Peat
2013/3/7
A method that could be used to detect the change of the environment was used to determine the input of trace elements from the atmospheric fallouts into the biosphere near Tomsk city (West Siberia, Ru...
Effect of peat quality on microbial greenhouse gas formation in an acidic fen
peat quality microbial greenhouse gas formation an acidic fen

Peatlands play an important role in the global carbon cycle and represent both an important stock of soil carbon and a substantial natural source of relevant greenhouse gases like CO2 and CH4. While i...
Small scale controls of greenhouse gas release under elevated N deposition rates in a restoring peat bog in NW Germany
Small scale controls greenhouse gas release N deposition rates
2010/1/15
In Central Europe, most bogs have a history of drainage and many of them are currently being restored. Success of restoration as well as greenhouse gas exchange of these bogs is influenced by environm...
CO2 exchange and carbon balance in two grassland sites on eutrophic drained peat soils
CO2 exchange carbon balance grassland sites eutrophic drained peat soils
2010/1/14
In this study we investigated the role of intensive and extensive dairy farm practices on CO2 exchange and the carbon balance of peatlands by means of eddy covariance (EC) measurements. Year long EC m...

Globally, peat lands are considered to be a sink of CO2, but a source when drained. Additionally, wet peat lands are thought to emit considerable amounts of CH4 and N2O. Hitherto, reliable and integra...
Halogens in pore water of peat bogs – the role of peat decomposition and dissolved organic matter
Halogens pore water peat bogs peat decomposition dissolved organic matter
2010/1/13
Halogens are strongly enriched in peat and peatlands and such they are one of their largest active terrestrial reservoir. The enrichment of halogens in peat is mainly attributed to the formation of or...
