Grenseområdene Norge-Russland. Luft- og nedbørkvalitet, årsrapport 2017.
Smelteverkene i NV-Russland slipper ut store mengder svoveldioksid (SO2) og tungmetaller. Utslippene påvirker luft- og nedbørkvalitet i grenseområdene. Miljøovervåkingen viser at grenseverdier for SO2 er overholdt i kalenderåret
2017, samt sesongmiddel vinter 2016/17. Målsettingsverdier for Ni og As er overholdt.

Discounting the effect of meteorology on trends in surface ozone: Development of statistical tools
This report presents the results using a statistical method to single out the influence of interannual meteorological variability on surface ozone. The reason for using such a tool is two-fold: Firstly, to explain the ozone levels in one specific year in terms of weather anomalies and secondly, to estimate the part of long-term ozone trends that is due to the meteorology alone. The method is a so-called GAM (generalized additive model), which could be regarded an advanced multiple regression method relating daily ozone levels to certain meteorological variables. The performance of the method was evaluated by comparing observed ozone data with those predicted by the GAM. This revealed a good to very good agreement in central Europe and Germany in particular. For southern Europe the performance was poorer. The method indicated that meteorology contributed to the downward trend in ozone seen at most sites for both 1990-2000 and 2000-2010.

Analyses of selected organic contaminants and metals in drinking bottles. Technical report.
On behalf of Norwegian Consumer Council NILU has conducted analyses of organic contaminants and metals in the leachate from selected drinking bottles. The simulation of the leakage is conducted based on a compilation of the methods described within NS-EN-1186-9 and NS-EN-13130-1. The instrumental analytical methods used were already established at NILU and NIVA. A number of different organic contaminants and metals have been found in trace amounts in the different products.

Environmental pollutants in the terrestrial and urban environment 2017
Abiotic and biotic samples from the terrestrial and urban environment were analysed for inorganic and various organic contaminants in the Oslo area. The species analysed were earthworms, fieldfare, sparrowhawk, brown rat, tawny owl, red fox and badger. Air and soil samples were also included in the study to increase the understanding on sources and uptake of pollutants. A foodchain approach was used, in order to detect trophic magnification of the different compounds.

Skogens helsetilstand i Norge. Resultater fra skogskadeovervåkingen i 2017
Skogens helsetilstand påvirkes i stor grad av klima og værforhold, enten direkte ved tørke, frost og vind, eller indirekte ved at klimaet påvirker omfanget av soppsykdommer og insektangrep. Klimaendringene og den forventede økningen i klimarelaterte skogskader gir store utfordringer for forvaltningen av framtidas skogressurser. Det samme gjør invaderende skadegjørere, både allerede etablerte arter og nye som kan komme til Norge i nær framtid. Denne rapporten presenterer resultater fra skogskadeovervåkingen i Norge i 2017 og trender over tid for følgende temaer...
