  1. 1. 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

  3. 2. Environmental transformations of Manganese and Manganese oxide nanoparticles

    University essay from KTH/Materialvetenskap

    Author : Lundberg Annie; [2020]
    Keywords : ;

    Abstract : Engineered nanoparticles (NPs) are produced in increased quantities. Due to this increase, itis vital to understand the full lifecycle and fate of these NPs to prevent any possible environmental stress. READ MORE

  4. 3. Mineralogical speciation of sulfur in acid sulfate soils from Luleå, Sweden

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Niklas Gunnarsson; [2018]
    Keywords : acid sulfate soil; metal leakage; low pH; SEM; elemental sulfur; framboidal pyrite;

    Abstract : Marine sulfide – bearing sediments that oxidize when in contact with oxygen and leach outelements in high concentrations to small watercourses have been a problem for many years allover the world especially around the Bothnian Bay. The purpose of this study was to furtherinvestigate the sulfur mineralogy present in acid sulfate soils in the area of Luleå, Sweden. READ MORE

  5. 4. Investigation of the origin of salt in coastal aquifers and assessment of metals in the aquatic environment : River Drin and River Vjosa, Albania

    University essay from KTH/Vatten- och miljöteknik

    Author : Maximilian von Bahr; Ida Gomez Bergström; [2018]
    Keywords : Albania; aquifers; bioavailability; Drin; groundwater; isotope analysis; metal speciation; river; saltwater intrusion; Vjosa;

    Abstract : The preservation of freshwater aquifers is one important task of managing natural resources today. Intrusion of saltwater from the sea into the groundwater might occur in coastal-near areas and can affect the freshwater quality negatively. READ MORE

  6. 5. Metal Fractionation in Snowmelt Runoff : A Comparison between Ultrafiltration and Diffusive Gradients in Thin Films (DGT) techniques

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

    Author : Sarah Lindfors; [2017]
    Keywords : Urban Runoff; Metals; Ultrafiltration; Diffusive Gradients in Thin Films;

    Abstract : Urban runoff is a non-point pollution source deteriorating water quality of natural watersystems. The composition of urban runoff vary depending on land use, seasonal changes anddifferent surfaces that come into contact with the water. READ MORE
