  1. 11. Newly inundated forest landscapes - hotspots for mercury in water and benthic fauna

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Kirstine Evald Andersson; [2023]
    Keywords : Wetland restoration; Inundation; Mercury cycling; Beaver impoundments; Aquatic biogeochemis-try;

    Abstract : Mercury (Hg) is a widespread contaminant in high-latitude aquatic ecosystems, where it can undergo microbial transfor-mation into toxic methylmercury (MeHg). Due to its chemical properties, MeHg tends to accumulate in the aquatic food chain and will eventually end up in predatory species at the top of the terrestrial food web. READ MORE

  3. 12. Effects of Forest Ditch Cleaning on Surface Water Quality

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Emeli Arvidsson; [2023]
    Keywords : Ditch cleaning; forest clear-cut; water quality; water chemistry;

    Abstract : Ditch cleaning (DC) is recommended by authorities to Swedish landowners to maintain forest productivity after forest harvest by lowering groundwater tables of catchment soils. Knowledge regarding the impact of this practice on surface water quality is limited, and results from previous research vary. READ MORE

  4. 13. Biokol i foder till värphöns och slaktkycklingar

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Viktor Mattsson; [2023]
    Keywords : biokol; foder; värphöns; ; kyckling; produktionsegenskaper;

    Abstract : Inom produktionen av kyckling och ägg så är fodret den absolut största kostnaden. Ett bra foder är viktigt för att uppnå en bra produktion. Detta har medfört att lantbrukare och forskare har letat efter alternativa foderråvaror och tillsatser som kan bidra med positiva effekter på djuren för att få en högre produktion. READ MORE

  5. 14. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

    University essay from

    Author : Delshad Mansour Ayoubi; [2022-12-06]
    Keywords : Medical physics; Activity concentration; Transfer coefficient; Dose;

    Abstract : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. READ MORE

  6. 15. Biogeochemistry and Peat Properties of Restored Peatlands

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Pelle Belaieff Kronborg; [2022]
    Keywords : Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Abstract : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon. Drainage can turn peatlands to net sources of carbon dioxide. Peatlands have historically been drained to increase the productivity of agriculture and forestry. READ MORE
