  1. 21. Kartläggning av metallförekomst med XRF Väsmanstranden, Ludvika : En fördjupad riskbedömning

    Magister-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Anna Qvarforth; [2020]
    Nyckelord :Miljöriskanalys; Väsmanstranden; Ludvika; XRF;

    Sammanfattning : Abstract Centrally located in Ludvika, between the central station and the south-eastern part of Lake Väsman, the area called "Väsmanstranden" is located. The closeness to both Väsman and all its nearby natural deposits and the railroad have created excellent conditions for many businesses to flourish on the site over the years. LÄS MER

    Sammanfattning : Today there are many uncertainties in the form of a lack of knowledge about perfluorinated and polyfluorinated substances (PFAS) regarding long-term risks to health and the environment, there is no efficacy data for many environments. The fluorocarbon bond is the strongest chemical bond, which means that PFAS can be transported long distances, for example through water streams and into the atmosphere. LÄS MER

  4. 23. Groundwater denitrification by fluidized bioelectrochemical systems

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lena Bonin; [2020]
    Nyckelord :Bioelectrochemistry; fluidized bed reactor; bioremediation; denitrification; groundwater; reduced graphene oxide;

    Sammanfattning : Groundwater (GW) accounting for most of the freshwater available around the World, finding sustainable techniques to depollute it is of crucial importance for safe drinking water supply. The extensive use of fertilizers in the agriculture, as well as other anthropogenic activities, are contributing to the excessive nitrate levels in some aquifers. LÄS MER

  5. 24. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Eva Smedborn Pausson; [2019]
    Nyckelord :;

    Sammanfattning : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

  7. 25. Arsenic and other heavy metals in hydropower plants : An assessment of occupational risk hazards at Fortum’s underground hydropower plants in Sweden

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Angeliki Filippou; [2019]
    Nyckelord :;

    Sammanfattning : Arsenic (As) is a metalloid that occurs naturally in the Earth’s crust, in bedrock and soil. The concentrations that Arsenic can be found are normally between 1-3 ppm. LÄS MER
