    Author : Julia Iwan; [2021]
    Keywords : Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

    Abstract : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. READ MORE

  5. 4. Modelling Local pH Values and Ion Distributions near Gold Nanoparticles

    University essay from Umeå universitet/Kemiska institutionen

    Author : Lisa Tete; [2021]
    Keywords : ;

    Abstract : Corrosion is the sum of processes by which an element, commonly a metal, wears away, deteriorates [1]–[3]. One of these processes uses the principle of electrochemistry as a basis, being the transfer of electrons between one chemical reaction and the element that undergoes corrosion [4], [5]. READ MORE

  6. 5. Establishment of analytical methods to assess endocrine disrupting compounds in a swedish wastewater treatment plant : water sampling using the Novel TIMFIE Device

    University essay from SLU/Dept. of Aquatic Sciences and Assessment
