1. 1. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Amanda Carlund; [2023]
   Nyckelord :;

   Sammanfattning : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. LÄS MER

3. 2. Net Zero, Net Profit: An Analysis of Offshore UK Carbon Capture and Storage

   Master-uppsats, Lunds universitet/Kulturgeografi och ekonomisk geografi; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

   Författare :Alexander Verne Magnus Perry; [2023]
   Nyckelord :Marx; primitive fossil capital; carbon capture and storage; CCS; socio-ecological fix; defensive fix; hegemony; green capitalism; materialised ideology; Social Sciences;

   Sammanfattning : The UK government is legally bound to reach net zero greenhouse gas emissions by 2050 as part of its actions to address climate change. One prominent method of decarbonisation is carbon capture and storage (CCS), slated for deployment in two industrial clusters by the mid-2020s. LÄS MER

4. 3. Greenhouse gas emissions and carbon burial in a small pond

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Maria Carlson; [2023]
   Nyckelord :Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

   Sammanfattning : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. LÄS MER

5. 4. Methane Sulphonic Acid in East Antarctic Coastal Firn and Ice Cores and Its Relationship with Chlorophyll-a and Sea Ice Extent in the Southern Ocean

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Emma Nilsson; [2022]
   Nyckelord :methane sulphonic acid; firn cores; sea ice proxy; marine primary productivity; Fimbul Ice Shelf; Dronning Maud Land; metansulfonsyra; firnkärnor; havsis-proxy; marin primärproduktion; Fimbulisen; Dronning Maud Land;

   Sammanfattning : The seasonal retreat of sea ice in the austral spring and summer around Antarctica has a significant effect on phytoplankton activity, mainly due to light availability, meltwater input of dissolved iron, and surface water stratification. Phytoplankton produce dimethylsulfoniopropionate, the precursor to the climate-cooling gas dimethyl sulphide, which is ventilated to the atmosphere and oxidised to methane sulphonic acid (MSA).

7. 5. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Simone Facchini; [2022]
   Nyckelord :organic chemistry; membranes; isatin; polymers; Chemistry;

   Sammanfattning : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. LÄS MER
