Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Norwegian goat milk production is based on summer grazing on diverse forest or alpine rangeland, and the quality of these pastures is important for milk quantity and quality. We used n-alkanes and long chained alcohols found in plant wax as markers to estimate diet composition in goats grazing on a heterogeneous rangeland during two periods in summer; early (beginning of July) and late (end of August). The goats were fitted with GPS collars that recorded their position. Preliminary results show a diverse diet, where ferns, sedges, blueberry (Vaccinium myrtillis) and birch were preferred in early summer. In late summer the diet was particularly diverse, coinciding with a general decline in plant quality.

Norway has the world’s largest facility for testing and improving CO2 capture. The aim of carbon capture technology is to minimize greenhouse gas emissions through a reaction between amines and effluents from gas power plants. During the overall process of CO2 capture, amines and their transformation products might escape to the environment through emissions, leakage, and as solid waste. The two main groups of transformation products with the most potential to cause environmental harm have been identified as nitrosamines and nitramines, both of which are considered to be carcinogenic. Recent theoretical modelling as well as laboratory experiments have found nitramine compounds, 2-nitroaminoethanol (CAS: 74386-82-6) and dimethylnitramine (CAS: 4164-28-7) to be present. However, despite the likelihood of these compounds increasing in the environment, no environmental toxicity data for these compounds currently exist. The aim of this project was to provide an environmental risk assessment for the selected nitramine compounds taking into account the key trophic groups within freshwater, marine and terrestrial environments. The toxicity assessment was made using a suite of standardised bioassays for the measure of acute and chronic toxicity. In the soil environment, the most potent compound was 2-nitroaminoethanol, which impaired the reproduction of earthworms and the seedling emergence of sunflower and ryegrass. The opposite was found in the aquatic environment, with freshwater and marine species consistently more affected by dimethylnitramine. All the tested freshwater species were more sensitive to nitramines than marine species. The selected amines were not acutely toxic to aquatic and soil species, with EC50 in the mg/L range. Both nitramines increased the nitrogen and carbon transformation activity of soil microorganisms.
