  1. 16. 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 ekosystemvetenskap

    Author : Marcus Rudolf; [2016]
    Keywords : organic matter; spheroidal carbonaceous particles; black carbon; geology; physical geography; Ecosystem analysis; heavy metals; coastal sediments; Sweden; Earth and Environmental Sciences;

    Abstract : 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

  3. 17. Lignin degradation and oxygen dependence

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Niklas Olsson; [2016]
    Keywords : lignin; degradation; Clostridium; Desulfovibrio; metagenome; sheep;

    Abstract : This work concerns itself with the biological degradation of the lignin polymer. The chemical composition of the polymer makes it recalcitrant toward hydrolysis and other common chemical reactions occurring under biological conditions. READ MORE

  4. 18. Fate of four pharmaceuticals in aquatic ecosystems : Investigating the role of UV- light and animal assimilation as dissipation factors

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Niklas Ekelund Nord; [2015]
    Keywords : ;

    Abstract : Pharmaceuticals in the aquatic environment are of concern due to its possible negative consequences for non-target species. Pharmaceuticals can be found in many parts of the environment and especially in the effluent from sewage treatment plants where pharmaceuticals can be found in significant quantities. READ MORE

  5. 19. Effect of vegetable oil on the degradation of a pesticide mixture in biobeds

    University essay from SLU/Dept. of Microbiology

    Author : Johanna Moreskog; [2013]
    Keywords : Pesticides; Biobed; Ligninolytic enzymes; Maganese peroxidase;

    Abstract : Pesticides are used to control diseases, undesired vegetation and insects in forestry, gardening and agriculture. In the environment, pesticides are generally believed to originate from a diffuse source, such as spray drift of pesticides during application, or a point source, such as spills during refill and cleaning of spraying equipment.

  6. 20. Identification and Characterization of Gene Functions Involved in Recalcitrant Compound Degradation Using Metagenomic Data

    University essay from Institutionen för naturvetenskap, miljö och teknik

    Author : Tino Lawson; [2012]
    Keywords : recalcitrant; dienelactone hydrolase; metagenomics;

    Abstract : With the environmental problems caused by man-induced pollution by persistent toxic compounds, the importance of finding remediation solutions is immense. As an emerging field, microbial environmental biotechnology may provide the tools to achieve novel solutions. READ MORE
