  1. 1. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anton Sandberg; [2023]
    Keywords : Framboidal pyrite; dredging; Sangis River; estuary; redox ladder; sediment; sediment cores; SEM-EDS;

    Abstract : It has been common in forestry and agriculture to drain waterlogged areas through ditching in order to cultivate them. The ditches that drain water are usually connected to some watercourse, such as a river. READ MORE

  3. 2. A Toxic Legacy? : A Study of PFAS Leakage from Landfills in the Eastern Part of Mälaren

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Elsa Hård af Segerstad; [2023]
    Keywords : Landfills; PFAS; Leachate; Mälaren-Görväln; Östra Mälaren Water Protection Area; Norrvatten; Drinking Water; Characterisation; Risk Assessment; Deponier; PFAS; Lakvatten; Mälaren-Görväln; Östra Mälarens vattenskyddsområde; Norrvatten; Dricksvatten; Karakterisering; Riskbedömning;

    Abstract : The growing concern around per- and polyfluoroalkyl substances (PFAS) and their negative health and environmental effects have lately become more apparent which also is reflected in the new, more strict regulations of permitted levels of PFAS in drinking water extracted from water resources. However, many point sources of PFAS pollution to the environment and to water resources are still not identified and assessed for risk. READ MORE

  4. 3. Some Like It Hot: Pre-heating Prior to Bioreactor Treatment Enhances Nitrogen Removal From Mine Drainage

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Laura Nina Bettoni; [2022]
    Keywords : denitrification; nitrate removal; temperature; woodchip bioreactor; waste rock leachate;

    Abstract : Ammonium-nitrate based explosives (NH4NO3) used within the operations of Kiruna iron ore mine release nitrate (NO3-) into the environment, potentially having adverse effects on local river-systems. One way of reducing NO3- impacts to the environment is through a woodchip denitrifying bioreactor (DBR). READ MORE

  5. 4. Leachate-Based Biotic Ligand Model for Soil : Ecotoxicological Risk Assessment of Copper for Invertebrates, Plants, and Soil Microbial Processes

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tove Florén; [2021]
    Keywords : Tomato shoot; Barley root; Glucose induced respiration; Nitrification; Earthworm; Springtail; EC10; SSD; Regression analysis; pH dependency; Bioavailability;

    Abstract : Environmental pollution of heavy metals has become an increasing problem. Environmental risk assessments can be conducted to investigate and determine the potential risk of polluted terrestrial environments. Traditionally, risk assessments are based on total soil metal concentrations on a dry weight basis. READ MORE

  6. 5. The potential for Binding PFAS Using Biochar and Phytoremediation

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Josefin Alice Maria Svensson; [2021]
    Keywords : Physical geography; ecosystem analysis; PFAS; Per-and polyfluoroalkyl substances; remediation; phytoremediation; biochar; Earth and Environmental Sciences;

    Abstract : PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. READ MORE
