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

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Amanda Carlund; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

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

   University essay from Uppsala universitet/Institutionen för geovetenskaper

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

   Abstract : 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. READ MORE

4. 3. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Yanhe Zhou; [2023]
   Keywords : Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

   Abstract : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. READ MORE

5. 4. Nitrogen legacies in agricultural catchments : an analysis of 170 years of nitrogen legacies data in four Swedish agricultural catchments

   University essay from SLU/Dept. of Soil and Environment

   Author : Laura-Ainhoa Prischl; [2023]
   Keywords : nitrogen mass balance; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture;

   Abstract : Despite the enforcement of legislation and application of measures, nitrogen (N) levels continue to be high in streams. One of the reasons for the low N reduction, is the legacy accumulation of N. READ MORE

6. 5. An Investigation of How Hydrophobicity, Water, and Surface Topography Influence Macroscopic Particle Accumulation on Surfaces : A Case Study of Grass Accumulation on Robotic Lawn Mower

   University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

   Author : Rasmus Brask-Nilsen; Petter Ydrestrand; [2023]
   Keywords : Macroscopic Particles; Accumulation; Hydrophobicity; Humidity; Topology; Adhesion; Experiments; Design of Experiments; Grass; Robotic Lawn Mower;

   Abstract : This master's thesis project investigates the impact of hydrophobicity and topology on dry and wet macroscopic particle accumulation on surfaces. The report begins by outlining the challenges associated with this phenomenon and the existing theories and methods used to study it, including adhesion, surface engineering, the Lotus effect, and humidity.
