1. 1. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Emilie Åström; [2022]
   Keywords : acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

   Abstract : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. READ MORE

3. 2. Sorption of PFOS to different solid components as a function of aqueous chemistry

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Jean Noël UWAYEZU; [2018]
   Keywords : ;

   Abstract : Knowledge of fate and transport of chemical contaminants in the environment is essential for reducing their adverse effects to humans and wildlife. Surface and ground waters serve as drinking water which helps to sustain life. READ MORE

4. 3. 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

5. 4. The 200-year history of nss-SO42- concentration in snow and ice from Lomonosovfonna, Svalbard

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Maria Schoeps; Josefin Andersson; [2015]
   Keywords : Sulfate; nss-SO42-; ice-cores; glaciochemistry; Lomonosovfonna; Sulfat; nss-SO42-; isborrkärnor; iskemi; Lomonosovfonna;

   Abstract : Environmental scientists use ice-core records to reconstruct past atmospheric conditions. Anthropogenic and natural sources of emissions can be traced when analyzing ions in the ice, which is included in the science of glaciochemistry. Sulfate is an excellent ion to use in these studies since it is traceable to these emissions. READ MORE

6. 5. 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
