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.

Summary: This experiment simulate aerobic treatment to see if the field removal rates can be duplicated in the laboratory, and also to see if there are some physical or chemical factors that significantly influence this removal. The experiment used 3 leachates and 8 artificial samples with varying concentrations of Cl, TOC, Tot-N and Fe, and 4 controls. Leachate samples were collected from Dal Skog and Esval landfills. Some of the samples were centrifuged after respiration.The oxygen consumption in the leachate samples was considerably lower than in the artificial samples, probably due to inhibitory compounds in the leachate. Mean Cl removal was 21.6% for the leachate samples, 46.0% in the artificial samples and 9.97% in the controls. Only TOC showed significant influence on the oxygen consumption in the respirometer, both when measured in the artificial samples (p< 0.036) and for all samples (p

Gjersjøen med tilløpsbekkene Dalselva og Greverudbekken er prøvetatt fra april til desember 1999. Der er ikke funnet plantevernmidler i råvannet (drikkevannet) til Gjersjøen. Det er påvist til sammen syv plantevernmidler i tilløpsbekkene. Disse har blitt nedbrutt og/eller fortynnet i vannmassene, slik at det ikke har vært målbare i råvannet.

This report presents an analysis of soil and water related environmental effects linked to agricultural production in the net exporting countries Australia, New Zealand and USA, and the net importing countries Japan, Norway and Switzerland. The study has been based on the following indicators: General features of the selected countries. Pesticide use, finding and concentration of pesticides in surface water and groundwater. Fertiliser use and nitrogen balance. Soil erosion, extent and rates of water erosion, risk of wind erosion. Water resources, agricultural withdrawals and water use efficiency. Water quality, nitrogen and phosphorous concentrations in surface water and groundwater. For soil erosion the overall tendency is a net environmental deterioration by expanding agricultural production in the net exporting countries as compared with the net importing country Norway. For agricultural withdrawals of water an expansion of agriculture in the net exporting countries may result in a net environmental detorioration versus the net importing countries Norway and Switzerland. For surface water and groundwater quality the effect of trade liberalisation is more uncertain.
