Project description

This master project investigates concentration, distribution and transportation of heavy metals connected to the mining industry at Litlabø. The Litlabø mine was opened in 1865 and were active until 1968. After the mine were closed it has become water filled and material from the mines have been spread and covered. Drainage from the mining area shows low pH-values and pollution from heavy metals. Sediments and pore water from sediment cores and water samples from the Storvannet lake and the marine Sagvåg harbour pool will be analyzed. This includes structural, geochemical and geomicrobiological analyses such as XRF-scanning, CT-scanning, ICP-OES/MS fluid sample analysis and DNA analysis. An effort to identify ash particles from known volcanic eruptions on Island will also be used to provide a detailed chronological framework for the study area.
