  1. 1. Stadsodling i Hamnparken, Nyhamnen Malmö : undersöker Torontomodellen som beslutsstöd för potentiellt förorenad mark

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Lova Hambraeus; Karin Stureson; [2024]
    Keywords : bly Pb ; fytoremediering; markanalys; miljöföroreningar; Nyhamnen; PAH; stadsodling; Torontomodellen;

    Abstract : Befolkningen ökar och städer blir tätare. Detta skapar ett behov av att utöka matproduktionen och stärka livsmedelsförsörjningen i staden, samt bygga upp platser för mental hälsa och social interaktion. Ett möjligt sätt att göra detta är genom att börja stadsodla. READ MORE

  3. 2. 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.

  4. 3. Thermodynamic modelling of the copper-zinc-tin ternary system : A study towards lead-free brass

    University essay from KTH/Materialvetenskap

    Author : Caterina Radogna; [2023]
    Keywords : Brass-based alloys; Lead-free brass; Calphad; Thermo-Calc; Thermodynamic description; Mässingsbaserade legeringar; Blyfri mässing; Calphad; Thermo-Calc; Termodynamisk beskrivning;

    Abstract : Lead (Pb) is frequently used as an alloying element in brass to enhance machinability and castability. However, this element poses a significant risk to human health and the environment. The 2021 revision of the Drinking Water Directive imposed stricter limits on Pb content in brass, encouraging the development of lead-free brass. READ MORE

  5. 4. Analysis on copper, lead and tin removal in steel scrap sorting : Technologies involved, environmental considerations and economic aspects

    University essay from KTH/Materialvetenskap
