  1. 6. How Do Long-Term Declines in Anthropogenic Sulfur Dioxide Emissions and Sulfate Wet Deposition Compare with Trends in Freshwater Chemistry in Scandinavian Rivers?

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Linnea Georgii; [2017]
    Keywords : sulfur dioxide; SO2; SO42-; river chemistry; Scandinavia; Sweden; Norway; svaveldioxid; SO2; SO42-; vattendrag; Skandinavien; Sverige; Norge;

    Abstract : Acidification of precipitation is an important environmental problem that emerged during the past century, especially after the Second World War. Acidification was primarily caused by human-made emissions of SOx (mostly SO2) and NOx, which are oxidized sulfur and nitrogen gases. READ MORE

  3. 7. A Freundlich-based model for prediction of pH-dependent sulfate adsorption in forest soil.

    University essay from KTH/Mark- och vattenteknik

    Author : Muhammad Akram; [2015]
    Keywords : Sulfate; Spodosols; pH Dependent Sulfate Adsorption; Extended Freundlich Model;

    Abstract : The period of industrialization after the second World War in Europe released SO2 and NOx by combustion of fossil fuels and contributed the formation of S and N compounds in the forest ecosystem. The Swedish forest soil systems were influenced by emissions of SO2 followed by H2SO4 deposition, consequently the pool of SO42- had increased in the forest ecosystem. READ MORE

  4. 8. Long term organic carbon dynamics in 17 Swedish lakes : The impact of acid deposition and climate change

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jessica Lovell; [2015]
    Keywords : environmental monitoring; climate change; sulfate deposition; total organic carbon TOC ; VNIRS; trend analysis; multivariate data analysis; PLS; miljöövervakning; klimatförändringar; sulfat deposition; organiskt kol; TOC; VNIRS; trendanalys; multivariat data analys; PLS;

    Abstract : During the last three decades, a number of studies based on national environmental monitoring data have found increased concentrations of total organic carbon (TOC) in surface waters in much of the northern hemisphere including Sweden. There are many hypothesis of what has been the main cause of this trend, including changes in land use, decreased atmospheric deposition of acidifying compounds and climate change. READ MORE

  5. 9. Surhetstillståndet i bäckar uppströmskalkdoserare i Dalarnas län

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Goulnara Khoussainova; [2010]
    Keywords : försurningsbedömning; buffertkapacitet; surhetstillstånd; kalkning; vattenkemisk analys;

    Abstract : The acid deposition of sulphur- and nitrogenoxides from combustion of coal and oil cause acidification that lowers pH and gives increased contents of metals and altered aquatic biodiversity in the stream. The liming of lakes and streams, which was introduced to resist the acidification, demand large economic resourses despite of the decreased deposition of the acidifyng substances. READ MORE
