  • Fluorinated Precursor Compounds in Sediments as a Source of Perfluorinated Alkyl Acids (PFAA) to Biota 

    Langberg, Håkon Austad; Breedveld, Gijs D.; Slinde, Gøril Aasen; Grønning, Hege Mentzoni; Høisæter, Åse; Jartun, Morten; Rundberget, Thomas; Jenssen, Bjørn Munro; Hale, Sarah (Peer reviewed; Journal article, 2020)
    The environmental behavior of perfluorinated alkyl acids (PFAA) and their precursors was investigated in lake Tyrifjorden, downstream a factory producing paper products coated with per- and polyfluorinated alkyl substances ...
  • Comparing nutrient reference concentrations in Nordic countries with focus on lowland rivers 

    Skarbøvik, Eva; Aroviita, Jukka; Fölster, Jens; Solheim, Anne Lyche; Kyllmar, Katarina; Rankinen, Katri; Kronvang, Brian (Peer reviewed; Journal article, 2020)
    Reference conditions of water bodies are defined as the natural or minimal anthropogenically disturbed state. We compared the methods for determining total phosphorus and total nitrogen concentrations in rivers in Finland, ...
  • Evaluering av ØKOKYST - stasjonsnett og klassegrenser 

    Walday, Mats Gunnar; Fagerli, Camilla With; Frigstad, Helene; Staalstrøm, Andre; Kaurin, Maria; Christensen, Guttorm; Trannum, Hilde Cecilie; Eikrem, Wenche (NIVA-rapport;7527, Research report, 2020)
    Overvåkingsprogrammet "Økosystemovervåking i Kystvann – ØKOKYST" har til hensikt å overvåke miljøtilstanden i utvalgte områder langs norskekysten i henhold til vannforskriften. Miljødirektoratet har bedt NIVA gjennomgå ...
  • Correcting for bias in freshwater total nitrogen concentrations obtained with a modified standard (NS4743) method 

    Thrane, Jan-Erik; de Wit, Heleen; Blakseth, Tomas Adler; Skancke, Liv Bente; Garmo, Øyvind Aaberg (NIVA-rapport;7538, Research report, 2020)
    Concentrations of total nitrogen (TotN) in freshwater monitoring programs were unreliable for a limited period, probably because of inadequate sample digestion when using a modified version of method NS 4743 (“method A”) ...
  • Potential impacts of a future Nordic bioeconomy on surface water quality 

    Marttila, Hannu; Lepistö, Ahti; Tolvanen, Anne; Bechmann, Marianne; Kyllmar, Katarina; Juutinen, Artti; Wenng, Hannah Tabea; Skarbøvik, Eva; Futter, Martyn; Kortelainen, Pirkko; Rankinen, Katri; Hellsten, Seppo; Kløve, Bjørn; Kronvang, Brian; Kaste, Øyvind; Solheim, Anne Lyche; Bhattacharjee, Joy; Rakovic, Jelena; de Wit, Heleen (Peer reviewed; Journal article, 2020)
    Nordic water bodies face multiple stressors due to human activities, generating diffuse loading and climate change. The ‘green shift’ towards a bio-based economy poses new demands and increased pressure on the environment. ...
