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.

Alum shale and till soils overlying alum shale bedrock were analysed for aqua regia and NH4OAc/EDTA extractable Pb, Cu, Zn, Ni, Mn and Cd. The means of these determinations were compared with those of Norwegian, Finnish and Swedish non-alum shale soils. Alum shale soils seemed to contain higher amounts of both total and easily extractable Cu, Zn, Ni and Cd. Total Pb content also seemed to be higher in the alum shale soils. The relative availability of Cd, Ni and Mn, expressed as the ratio of NH4OAc/EDTA to aqua regia extractable, was found to be greater than that of Pb, Cu and Zn in the alum shale and till soils.

Pulverized rock samples of alum shale were agitated in distilled water for up to 100 days, in acid solutions of increasing concentrations for 24 h, and lastly treated with increasing amounts of lime as CaCO3 and equilibrated for 100 days. The effects of the different treatments on the release of Fe, Cu, Zn, Ni, Cd, Pb and Mn were studied. The aging experiment indicated that, with time, large amounts of heavy metals may be released by alum shales. The MUNCH sample, with a high buffer capacity against acid, was found to be slow in heavy metal release. The high correlation coefficients for added H+ versus % of total metal released, however, reflect that under the influence of "foreign" acids, this sample will also be capable of releasing heavy metals relatively easily. Liming was effective in rendering the heavy metals immobile. 90-100 tons of CaCO3 were found to be enough to immobilise most of the metals released from a shale waste to an acceptable level, assuming a shale waste density of 1-2 kg dm-3.
