Transformation as praxis: responding to climate change uncertainties in marginal environments in South Asia
(Peer reviewed; Journal article, 2021)This paper provides some of the conceptual and methodological underpinnings being developed in the ongoing TAPESTRY project which is part of the Transformations to Sustainability (T2S) Programme. We debate how the notion ... -
Transformation Kinetics of Burnt Lime in Freshwater and Sea Water
(Peer reviewed; Journal article, 2020)Calcium oxide (CaO), also known as burnt lime, is being considered as a possible treatment to reduce the negative impact of sea urchins on tare forests in northern coastal waters and blue-green algal blooms in the surrounding ... -
Transgenic (cyp19a1b-GFP) zebrafish embryos as a tool for assessing combined effects of oestrogenic chemicals
(Journal article; Peer reviewed, 2013)Endocrine disrupting chemicals and especially oestrogen receptor (ER) agonists have been extensively studied over the years due to their potential effects on sexual development and reproduction in vertebrates, notably fish. ... -

Trends and patterns in surface water chemistry in Europe and North America between 1990 and 2020, with a focus on calcium
(NIVA-rapport;7931-2024, Research report, 2024)The report presents trends in major anions and cations, pH, TOC and bicarbonate in surface waters in Europe and North America from 1990 to 2020. Special attention is given to trends in calcium, which showed some unexpected ... -
Trends and potential human health risk of trace elements accumulated in transplanted blue mussels during restoration activities of Flekkefjord fjord (Southern Norway)
(Peer reviewed; Journal article, 2022)The monitoring of contaminants represents a priority to preserve the integrity of marine ecosystems, as well as to plan and to manage restoration activities in order to protect environmental and human health. In the present ... -
Trends in ecosystem and health responses to long-rangetransported atmospheric pollutants - ICP Waters report125/2015
(NIVA-rapport;6946, Research report, 2015)The aim of this trend report is to assess the effectiveness of air pollution policies under the Convention on Long-range Transboundary Air Pollution (LRTAP), and to document progress and identify remaining challenges. ... -
Trends in surface water chemistry in acidified areas in Europe and North America from 1990 to 2008
(Journal article; Peer reviewed, 2014)Acidification of lakes and rivers is still an environmental concern despite reduced emissions of acidifying compounds. We analysed trends in surface water chemistry of 173 acid-sensitive sites from 12 regions in Europe and ... -
Tryptophan metabolic pathways and brain serotonergic activity: A comparative review
(Journal article; Peer reviewed, 2019)The essential amino acid L-tryptophan (Trp) is the precursor of the monoaminergic neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Numerous studies have shown that elevated dietary Trp has a suppressive effect on ... -
Two different approaches of microbial community structure characterization in riverine epilithic biofilms under multiple stressors conditions: Developing molecular indicators
(Peer reviewed; Journal article, 2021)Microbial communities are major players in the biogeochemical processes and ecosystem functioning of river networks. Despite their importance in the ecosystem, biomonitoring tools relying on prokaryotes are still lacking. ... -
Two stage algorithm vs commonly used approaches for the suspect screening of complex environmental samples analyzed via liquid chromatography high resolution time of flight mass spectroscopy: A test study
(Journal article; Peer reviewed, 2017)LC-HR-QTOF-MS recently has become a commonly used approach for the analysis of complex samples. However, identification of small organic molecules in complex samples with the highest level of confidence is a challenging ... -
Tørke og effekter på vannkvalitet og biota i lite påvirkede vassdrag i Norge
(NIVA-rapport;7786-2022, Research report, 2022)I denne rapporten har vi har vi brukt overvåkingsdata fra lite påvirkede vassdrag for å studere effekter av tørke på vannkvalitet og biota. Vi sammenliknet vannkjemiske og biologiske data fra tørkesommeren 2018 (som våre ... -
Ultrafast Electrochemical Self-Doping of Anodic Titanium Dioxide Nanotubes for Enhanced Electroanalytical and Photocatalytic Performance
