   University essay from Lunds universitet/Statistiska institutionen

   Author : Elias Gullberg; [2024]
   Keywords : Linear Mixed Models; Mathematics and Statistics;

   Abstract : Barnviken in Malmö has persistently encountered challenges associated with elevated concentrations of Escherichia coli (E. coli) without a discernible source of contamination. READ MORE

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

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Jonatan Uusitalo; [2023-08-17]
   Keywords : ;

   Abstract : 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.

4. 3. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Abstract : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

5. 4. Microplastics in Scanian wetlands : Sege river & Kävlinge river

   University essay from Malmö universitet/Institutionen för Urbana Studier (US)

   Author : Ludvig Stoltz; Pernilla Leijon; [2023]
   Keywords : plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

   Abstract : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. READ MORE

6. 5. Study of the effects of the operating conditions of a decanter centrifuge on a pilot-scale protein recovery setup from cold-pressed rapeseed press cake

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Sergio de La Cruz Padilla; [2023]
   Keywords : By-product; Rapeseed press cake; protein; Food engineering; Agriculture and Food Sciences; Technology and Engineering;

   Abstract : There is significant evidence to suggest that diets that include high levels of meat consumption have negative effects on both the environment and human health. As a result, efforts are being made to identify and characterize more plant-based proteins, such as those found in rapeseed. READ MORE
