1. Carbonaceous aerosols and trace metal deposition in high-latitude snow : a comparative study in Sweden and Alaska
University essay from SLU/Dept. of Soil and EnvironmentAbstract : This study investigates the advantages and disadvantages of several destructive and non-destructive analytical methods that can be employed to characterize airborne par-ticulate matter (PM) deposited in seasonal snow. To this end, a comparative study was conducted on PM obtained from snowpack surveys in two Arctic/subarctic regions of Northern Sweden and Interior Alaska, USA. READ MORE

2. Characterizing particulate carbon using dielectric property measurements
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Interest in effects of carbonaceous particles in the atmosphere has recently taken an upswing due to knowledge of how these particles affect our environment. Carbonaceous aerosols are characterized by their dark color, giving them the ability to absorb both incoming and outgoing radiation of all wavelengths in the atmosphere. READ MORE

3. Atmospheric Particles in Kermanshah, Iran
University essay from Lunds universitet/Atomfysik; Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenAbstract : No measurements of airborne particles have been done in Iran previously. Starting characterization of aerosol particles in a completely new geographical area, a suitable and important measurement parameter is the aerosol particle number size distribution. This can be used to indirectly infer climate- and health effects of the particles. READ MORE

4. Spatiotemporal reconstructions of black carbon, organic matter and heavy metals in coastal records of south-west Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : This study presents reconstructions of black carbon (BC), including spheroidal and amorphous carbonaceous particles (SCP and ACP), organic matter (OM; total organic carbon, TOC; total nitrogen, TN; total sulfur, TS), and heavy metals (Fe, Zn, Pb, Cu, As and Hg) in coastal sediments off the south-west coast of Sweden. Sediment records from eight stations along a north-south transect off the south-west of Sweden were retrieved. READ MORE

5. Distribution of black carbon and its impact on Eutrophication in Lake Victoria
University essay from Linköpings universitet/Tema MiljöförändringAbstract : Lake Victoria (LV), is the largest tropical fresh water lake. It is however facing a myriad of challenges like eutrophication, introducing species, mass extinction and climate change. Eutrophication has mostly been seen as a result of non-point pollution from upstream agricultural areas. READ MORE
