    Author : Linnea Savér; Marcus Norlin; [2022]
    Keywords : Multi-metals monitoring; On-line monitoring; Aerosols; Diffuse dust; Environmental management; Secondary lead smelting; Technology and Engineering;

    Abstract : Boliden Bergsöe operates a secondary lead smelter for recycling of lead-acid batteries, located in the industrial area of Landskrona. Measurements to monitor levels of airborne particles have been conducted in several locations in Landskrona since 1977. READ MORE

  3. 27. Novel Scale Chemistry of Salmo Salar L. : New Linkage of Otolith and Scale Chemistry to M74 Reproductive Disorder

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Michelle Von Ehr; [2022]
    Keywords : Thiamine; M74; Salmon; Otolith chemistry; Scale chemistry; laser-ablation coupled inductively plasma mass spectrometry;

    Abstract : Baltic salmon suffer from maternally transmitted M74 reproductive disorder, which causes yolk-sac fry mortality due to thiamine deficiency. This study investigates trace elemental analyses of Baltic salmon applied on otoliths and scales and their possible link to identifying M74. READ MORE

  4. 28. Projections for charm balance functions in heavy-ion collisions

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Tilde Bonnevier Wallstedt; [2022]
    Keywords : Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

    Abstract : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. READ MORE

    Keywords : Zinkgruvan; Bergslagen; Cobalt; Sphalerite; Pyrrhotite; Safflorite;

    Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag deposit located in the Bergslagen ore district in south central Sweden. Elevated concentrations of cobalt have been detected in zinc ore from the mine. READ MORE

  6. 30. Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Amanda Lindgren; [2021-03-10]
    Keywords : acid sulphate soils; metal distribution; surface water; climate; physicochemistry;

    Abstract : Acid sulphate soils have been referred to as being among the most harmful soils in the world due to their ability to severely decrease the pH of the water, consequently enabling an increased metal load to recipient water streams, lakes, groundwater reservoirs and estuaries. The presence of acid sulphate soils has triggered several fish kill episodes in northern Scandinavia and the soils are today threatening many of the national environmental goals of Sweden. READ MORE
