  1. 1. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Chen Luo; [2020]
    Keywords : acid mine drainage; arsenic; cadmium; geochemical modeling; heavy metals; lead; principal component analysis;

    Abstract : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.

  2. 2. Binding of per- and polyfluoroalkyl substances (PFASs) to organic soil horizons of peat and mor : effect of solution chemistry and soil organic matter composition

    University essay from SLU/Dept. of Soil and Environment

    Author : Jennifer Makselon; [2019]
    Keywords : sorption; electrostatic interactions; isotherms; partitioning coefficient; soil organic matter; cation; PFOS; PFOA; desorption;

    Abstract : The understanding of sorption processes of per- and polyfluoroalkyl substances (PFASs) in soils is important for the determination of their fate and transport in the environment. The sorption behavior of PFASs of varying chain length and hydrophilic headgroup was studied in three organic soils, two peat soils and one mor layer, with differing chemical composition of the soil organic matter (SOM).

  3. 3. Sorption of perfluorinated and polyfluorinated alkylated substances (PFASs) in the subsurface of an industrial site in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Carl Sköld; [2019]
    Keywords : Sorption; soil-water partitioning; Kd; PFOS; PFOA; PFHxS; Sorption; fördelningskoefficient; Kd; PFOS; PFOA; PFHxS;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of emerging chemicals which havereceived increasing attention due to their toxicity, persistent properties, and global distribution.In this study, sorption coefficients (Kd and KOC) of PFASs in an industrial site in Sweden wereevaluated.

  4. 4. Long-term application of digestate and biofuel ash to arable soil : effects on the solubility of Cd, Al and trace metals as evidenced by simulated scenarios

    University essay from SLU/Dept. of Soil and Environment

    Author : Elias Bäckström; [2018]
    Keywords : cadmium; fertilizer; Visual MINTEQ;

    Abstract : The importance of nutrient recycling could not be emphasized enough in to-day’s society. Reduction of waste as well as recycling of nutrients would be the result if ash and biogas digestate could be used as fertilizer. However, the solubility of Cd, Al and micronutrients might be affected in a different way than by standard fertilizers. READ MORE

  5. 5. Electrodialytic Remediation of PFAS-Contaminated Soil

    University essay from KTH/Vatten- och miljöteknik

    Author : Georgios Niarchos; [2018]
    Keywords : Per- and polyfluoroalkyl substances; Electrokinetic; Ground; Groundwater; Treatment; Electrochemistry; Environment; Per- och polyfluoralkylsubstanser; Electrokinetisk; Grundvatten; Förorening; Elektrokemi; Miljö;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of anthropogenic aliphatic compounds, widelyknown for their environmental persistence and toxicity to living beings. While they are ubiquitous in theenvironment, interest has been focused on contaminated soil, which can act as a primary recipient andsource of groundwater contamination. READ MORE
