  1. 16. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Stéphanie Nyström; [2022]
    Nyckelord :Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Sammanfattning : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  3. 17. Tribolysis : – Reaction of Aromatic Halides for Potential Dehalogenation

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Oluwaseunnla P. Adelusi; [2022]
    Nyckelord :Tribolysis; Tribology; Mechanochemical Processing; Dehalogenation; Dechlorination; Remediation; Persistent Organic Pollutants; POPs; Polychlorinated biphenyls; PCBs; Dichlorotoluene ;

    Sammanfattning : Out of the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015, chemicals and waste management are obtainable under six. Improper and unsafe disposal of toxic chemicals into the environment affects life below water (SDG 14), human health and well-being (SDG 7), and clean water and sanitation (SDG 6). LÄS MER

  4. 18. Vulnerability assessment of groundwater pollution in the vicinity of a landfill in Nigeria

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

    Nyckelord :Olusosun landfill; Lagos; Nigeria; Groundwater quality assessment; Groundwater; Contamination; Deponin Olusosun; Lagos; Nigeria Grundvattenkvalitetsbedömning; Grundvatten; Förorening;

    Sammanfattning : Malfunctioning landfills are a globally sprawled problem. The Olusosun landfill in Lagos, Nigeria is not an exception. It is located in the middle of the city, nearby groundwater resources used to supply drinking water for the inhabitants in Lagos. LÄS MER

  5. 19. Phytoremediation potential for poly- and perfluoroalkyl substances (PFASs) using various plant species

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Tien-Chi Wu; [2021]
    Nyckelord :phytoremediation; PFAS; mustard; sunflower; industrial hemp; soil; plant;

    Sammanfattning : Poly- and perfluoroalkyl substances (PFASs) have unique chemical characteristics and are used in a wide variety of products. PFASs have been found in wild animals and humans and have shown adverse effects. Different remediation methods have been developed to remediate PFASs in the environment. LÄS MER

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

    Författare :Niklas Johansson; [2021]
    Nyckelord :in situ; remediation; enhanced biodegradation; BTEX; benzene; toluene; ethylbenzene; xylenes; petrol; filling station; soil pollution; groundwater; oxidiser; parameter; environment; in situ; sanering; förhöjd biologisk nedbrytning; BTEX; bensen; toluen; etylbensen; xyleber; bensin; drivmedelsanläggning; bensinstation; markförorening; grundvatten; oxidationsmedel; parameter; miljö;

    Sammanfattning : En av de vanligaste föroreningarna i mark och grundvatten är aromatiska kolvä- ten såsom bensen, toluen, etylbensen och xylener. Dessa härstammar från ex. ben- sin och har läckt ut till omgivande miljö från drivmedelsanläggningar. LÄS MER
