1. 1. Emission of greenhouse gases from constructed wetlands : Nutrient status in relation to methane and nitrous oxide emission

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Christian Lundström; [2022]
   Keywords : Constructed wetland; greenhouse gas emission; nutrient status; ebullition; Anlagd våtmark; växthusgasutsläpp; näringsstatus; ebullition;

   Abstract : Agricultural land releases large amounts of nitrogen and phosphorus to water bodies which causes eutrophication. Creating wetlands on agricultural land is one way to prevent this major issue. However, constructed wetlands are a large emission source of greenhouse gases. READ MORE

3. 2. 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

4. 3. Identification and quantification ofmicrobiological risks in board production : A study of ATP bioluminescence and redox potential

   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Claudia Bartos; [2022]
   Keywords : ATP bioluminescense; redox potential; bacillus; board production;

   Abstract : Stora Enso is a well-established provider of renewable solution packaging and board materials.Board products for liquid packaging and folding cartons for food are particularly sensitive tothe microbiological contaminants. In the manufacturing process, microbiological growth occursdue to environmental favourable conditions. READ MORE

5. 4. Water quality and organic matter linkages in waters draining arable fields

   University essay from SLU/Dept. of Soil and Environment

   Author : Adam Eriksson; [2021]
   Keywords : Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

   Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

6. 5. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Frida Ekman; [2021]
   Keywords : Ekoln; Natural organic matter NOM ; Total organic matter TOC ; Colour; degradation; sedimentation; photooxidation; PFAS; MIKE 3 FM; Ekoln; naturligt organiskt material NOM ; totalt organiskt kol TOC ; färg; nedbrytning; sedimentation; foto-oxidation; PFAS; MIKE 3 FM;

   Abstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.
