  1. 11. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    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

  3. 12. Utility of bark chips for removal of fluorinatedorganic compounds in water samples at a hazardouswaste management facility

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Maria Ekesbo; [2021]
    Keywords : Pine bark; PFAS; extractable organofluorine; contaminated water and sorption efficiency.;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are synthetic compounds that have beenaround since 1940. They can be used in a variety of products such as fire-fighting foam, food packaging and cosmetic products. Many PFAS have potential toxic effects on both humans and animals which poses a problem due to their wide distribution and persistency. READ MORE

  5. 14. Rening av avloppsvatten med hjälp av svamp : hantering av läkemedel och andra mikroföroreningar med hjälp av mykoremediering

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Hannah Davidsson; [2020]
    Keywords : avloppsvatten; rening; mikroföroreningar; mykoremediering; svamp; reningsverk; lackas;

    Abstract : Dagens reningsverk kan inte hantera de flesta läkemedelsrester och andra mikroföroreningar som kommer till reningsverket vilket resulterar i att de återfinns i våra akvatiska miljöer. Därför pågår mycket forskning kring hur mikroföroreningar kan hanteras och avlägsnas innan de kommer till recipienten. READ MORE
