  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, ...

  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. ...
