1. 1. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Jonatan Uusitalo; [2023-08-17]
   Nyckelord :;

   Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.

3. 2. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Jonas Fahlman; [2023]
   Nyckelord :astrobiology; icy moons; subglacial lakes; ice dynamics; thermal regimes; extremophiles; anthropogenic contamination; astrobiologi; ismånar; subglaciala sjöar; is-dynamik; termiska regimer; extremofiler; antropologisk kontaminering;

   Sammanfattning : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

4. 3. Phosphorous Precipitation in Source Separated Greywater for Direct Environmental Release.

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Ashley Hall; [2022]
   Nyckelord :water; wastewater; source separation; greywater; phosphorous; precipitation; utfällning; Chemical Engineering; Technology and Engineering;

   Sammanfattning : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. LÄS MER

5. 4. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Amrith Kumar; [2022]
   Nyckelord :Coagulation; flocculation; jar test; microplastics; sedimentation; water treatment; Burktest; flockning; koagulering; mikroplaster; sedimentering; vattenrening;

   Sammanfattning : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.

7. 5. Environmental radiation measurements at Barsebäck nuclear power plant during the decommissioning phase

   Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

   Författare :Patrik Dahlström; [2022]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. LÄS MER
