(NIVA-rapport;6722, Research report, 2014)Det ble i 2010 igangsatt overvåking og undersøkelser av ål i Storelva, Tvedestrand, for å få generell kunnskap om forhold som innvirket på ålens økologi og overlevelse. Ål er i dag definert som kritisk truet i hele Europa. ... -
Evaluering av ØKOKYST - stasjonsnett og klassegrenser
(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 ... -
Examining the Relevance of the Microplastic-Associated Additive Fraction in Environmental Compartments
(Peer reviewed; Journal article, 2022)Plastic contamination is ubiquitous in the environment and has been related to increasing global plastic usage since the 1950s. Considering the omnipresence of additives in plastics, the risk posed by this contamination ... -
Experimental study of the permafrost thawing effect on the content of nutrients and heavy metals in seawater during abrasion destruction of the Arctic coast
(Peer reviewed; Journal article, 2021)In the context of global warming, the permafrost thawing could have a significant impact on the chemical composition of seawaters in the Arctic. Permafrost thawing is a potential source of organic and inorganic forms of ... -
Expert Assessment of Risks Posed by Climate Change and Anthropogenic Activities to Ecosystem Services in the Deep North Atlantic
(Journal article; Peer reviewed, 2019)Sustainable development of the ocean is a central policy objective in Europe through the Blue Growth Strategy and globally through parties to the Convention on Biological Diversity. Achieving sustainable exploitation of ... -
Exploring dynamics of riverine phosphorus exports under future climate change using a process-based catchment model
(Peer reviewed; Journal article, 2022)A quantitative understanding of riverine phosphorus (P) export in response to shifts in anthropogenic inputs, terrestrial retention, and climate is important for developing mitigation measures at a watershed scale. In this ... -
Exploring the Adsorption of Pb on Microalgae-Derived Biochar: A Versatile Material for Environmental Remediation and Electroanalytical Applications
(Peer reviewed; Journal article, 2022)Biochar, a carbon material obtained by pyrolysis of biomasses, is increasingly applied in environmental remediation and sensing thanks to its functional properties, cost-effectiveness and eco-friendliness. The adsorption ... -
Exploring the impacts of microplastics and associated chemicals in the terrestrial environment – Exposure of soil invertebrates to tire particles
(Peer reviewed; Journal article, 2021)Abrasion of tire wear is one of the largest sources of microplastics to the environment. Although most tire particles settle into soils, studies on their ecotoxicological impacts on the terrestrial environment are scarce. ... -
Exploring the impacts of plastics in soil - The effects of polyester textile fibers on soil invertebrates
(Peer reviewed; Journal article, 2020)Polyester fiber is one of the most abundant types of microplastics in the environment. A major proportion of the fibers entering wastewater treatment plants end up in sewage sludge, which is used as a soil fertilizer in ... -
Exploring the Potential of a Global Emerging Contaminant Early Warning Network through the Use of Retrospective Suspect Screening with High-Resolution Mass Spectrometry
(Journal article; Peer reviewed, 2018)A key challenge in the environmental and exposure sciences is to establish experimental evidence of the role of chemical exposure in human and environmental systems. High resolution and accurate tandem mass spectrometry ... -
