The Spatial Distribution and Fate of Trace Metals in Ombrotrophic Peat Bogs
Atmospheric deposition of heavy metals and other pollutants has substantially increased due to human activities over the past several hundred years. For some metals such as lead and mercury, these changes have been well studied because of their potentially harmful impact to human and ecosystem health. However, some aspects of metal transport and storage in the environment are still not well und...
متن کاملPeat humic acid properties and factors influencing their variability in a temperate bog ecosystem
Studies of the properties of soil organic matter are essential for understanding the humification reactions and soil diagenesis processes. The aim of this study is to analyse properties of peat and peat humic acids as well as factors influencing their variability. Humic acids isolated from an ombrotrophic bog peat profile were used as study objects. Relations among peat age, decomposition and h...
متن کاملEffect of peat decomposition and mass loss on historic mercury records in peat bogs from patagonia.
Ombrotrophic peat bogs have been widely used to evaluate long-term records of atmospheric mercury (Hg) deposition. One of the major aims of these investigations is the estimation of the increase in atmospheric Hg fluxes during the industrial age compared to preindustrial fluxes. Comparability of Hg accumulation rates calculated from density, peat accumulation rates, and Hg concentrations requir...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Acidophilic methanotrophic communities from Sphagnum peat bogs.
Highly enriched methanotrophic communities (> 25 serial transfers) were obtained from acidic ombrotrophic peat bogs from four boreal forest sites. The enrichment strategy involved using media conditions that were associated with the highest rates of methane uptake by the original peat samples, namely, the use of diluted mineral medium of low buffering capacity, moderate incubation temperature (...
