(NIVA-rapport;5839, Research report, 2009)Rapporten beskriver resultatene fra en undersøkelse av mulig forurensning fra et slamdeponi og en nedlagt søppelfylling i Tandeskogen i Ringsaker. Det ble ikke funnet indikasjoner på at deponiet for kloakkslam forurenser ... -
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 ... -
Exceedance of critical loads for lakes in Finland, Norway and Sweden: Reduction requirements for nitrogen and sulfur deposition
(NIVA-rapport;2841, Research report, 1993)The main goal of the present study was to evaluate the different ways of computing the exceedances and the reductions needed for N and S depositions. Two models for calculating the steady state critical loads for N and S ... -
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. ... -
