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.

The main purpose of the risk assessment is to assess the future risk from cadmium in mineral P-fertilisers to human health, soils and waters using model calculations. The risk assessment of Cd in mineral fertilisers has been performed according to procedures suggested by ERM (2000). The procedure consists of three modules: 1) The accumulation module; 2) The exposure module; 3) The risk characterisation module. Two scenarios for Cd in mineral P-fertilisers were used: 2.3 mg Cd kg-1 P2O5-(present level of Cd ) and 60 mg Cd kg-1 P2O5 average EU-level). In the accumulation module the future (in 100 years) concentration of Cd in soils was calculated using a mass balance model. Application of P-fertiliser containing 60 mg Cd kg-1 P2O5 increases the soil concentration of Cd by 16 to nearly 100 percent depending on type of crop and region. In the exposure module, the uptake of Cd from the soil to wheat, potato and carrot is calculated as well as the relative contribution from fertilisers to the human uptake of Cd. The application of P-fertilisers containing 60 mg Cd kg-1 P2O5 in 100 years increase the daily intake of Cd by 76 percent i.e from 9.6 to 16.9 µg person-1 day-1. Applying mineral P-fertilisers for 100 years with the present average level of Cd (2.3 mg Cd kg-1 P2O5) increase the daily human intake by 4.3 percent. Future application (100 years) of mineral P-fertilisers containing the present level of Cd (2.3 mg Cd kg-1 P2O5) results in minor changes in soil Cd concentrations. For human health the margin of safety (MOS) using fertiliser with this level of Cd is in the range 4-7 depending on the No (Lowest) Observable Adverse Effect Level (N(L)OAEL). Taking into consideration the uncertainties in the N(L)OAEL it seems advisable to keep the future application of Cd to soils from mineral P-fertilisers at as low level as possible. Using mineral P-fertilisers containing 60 mg Cd kg-1 P2O5 (EU level), MOS decreases by approximately 40%. The level of no effect concentrations for organisms in Norwegian soils and waters are uncertain and the representativeness of the suggested PNEC values for Norwegian conditions questionable. The calculations performed indicate however that organisms in surface waters seem to be at higher risk from Cd in mineral P-fertilisers than soil living organisms

Rognebærmøll kan gjera stor skade i eple dei åra det ikkje er nok bær på rogn. Mangel på effektive tiltak mot rognebærmøll er eit viktig hinder for auke i arealet av eple i økologisk dyrking. Artikkelen tek for seg møllen sin livssyklus, skadepotensial, utbygd system for varsling av åtak og aktuelle strategiar for å kunne kontrollere denne skadegjeraren i økologisk dyrking.
