National Air Quality Tool - AP5. Towns and industry. Data collection and validation of simplified method.. NILU rapport
The report gives an overview of data collection and validation for the developement of a simplified method for concentration estimates for towns and industry. The validation show considerable uncertainty in the estimates for percentile values of PM10, and it is recommended not to develop the simplified method further.

Monitoring of long-range transported air pollutants in Norway, annual report 2015. NILU report
This report presents results from the monitoring of atmospheric composition and deposition of air pollution in 2015, and focuses on main components in air and precipitation, particulate and gaseous phase of inorganic constituents, particulate carbonaceous matter, ground level ozone and particulate matter. The concentration levels was generally very low in 2015 compared to previous years.

NILU was commissioned by 8 Norwegian companies with FeSi-/Si-industry to perform passive air measurements of SO2 and PAH around the Finnfjord AS FeSi-smelter and to analyse microsilica dust samples from the companies.
Passive monthly samples were taken at 10 sampling sites around Finnfjord AS in the period October-December 2014. The PAH samples were analysed for 42 PAH compounds. 5-7-ring PAHs, i.e. particle bound components, were generally below the detection limit during the measurement period. There was no significant correlation of SO2 and PAH2-4-ring and thus no significant impact from the smelter was found in October-December 2014 for gaseous PAHs. An additional source of PAHs in winter was likely residential heating by wood burning.

Workshop on emerging pollutants in non-industrial indoor environments. NORMAN workshop report. NILU report
This workshop aimed to identify the current state of the art plus knowledge gaps and needs within the research field of CECs, covering both ¿old¿ and emerging SVOCs and NVOCs in non-industrial indoor environments. Further, it aimed to promote awareness of emerging pollutants in non-industrial indoor environments and the exchange of knowledge/ information, and to encourage enhanced collaboration by bringing together scientists in the field of CECs in indoor environments with expertise from building and consumer product sectors and stakeholders/regulatory authorities.

Environmental pollutants in the terrestrial and urban environment 2015. NILU report
We analysed biological samples from the terrestrial and urban environment for various inorganic and organic contaminants in the Oslo area. A foodchain approach was used, in order to detect bioaccumulation of the different compounds. The species analysed were earthworms, fieldfare, sparrowhawk, rats, tawny owl and red fox. Soil samples were also included in the study.

Air quality calculations for Oslo Airport. NILU rapport
Modelling of emission and dispersion shows that the largest emissions of NOX are caused by airplanes during take-off and final approach, but these emissions have little impact on ground level concentrations. The highest modelled concentration levels are located within the airport area, and are of similar size as concentrations modelled in central areas of Norwegian medium sized cities. The largest contribution comes from the aircrafts. The concentration of PM is largely decided by the background contribution. Occurrence of odour in the vicinity of the airport can be explained by the emission of hydrocarbons from aircraft in taxi-modes. Occurrence of darkening on house walls in vicinity of and further away from the airport has been investigated. It is mainly caused by growth of fungus. Investigation of possible impact from airport activity on fresh water bodies indicate that the glycol content in the use of de-icing of aircraft has the largest potential impact.

Air quality in Ny-Ålesund. Monitoring of local air quality 2014-2015. NILU report
The concentrations of the measured components are generally low and below national limit values for the protection of human health and critical levels for the protection of vegetation.
Wind from northern sectors gave the highest average concentrations of nitrogen oxides, which indicates the power station and the harbour as possible sources. From September 2014 to February 2015, volcanic eruptions at Iceland emitted large volumes of SO2, which gave episodes of elevated concentrations in Ny-Ålesund. The measurement results for CO2 show an annual variation with higher concentrations in the winter and lower in summer. Measured concentrations of CO were most likely caused by local snowmobile traffic and long-range transport of emissions from wildfires in North America.

Atmospheric deposition of organic contaminants in Norway: National moss survey 2015. NILU report
For the second Norwegian Moss survey on organic contaminants 20 samples were collected on the Norwegian mainland in rural areas presumably little affected by local point sources of pollutants. PeCB, HCB, PCB, HCH, DDT, PBDE, DBDPE, HBCD, PFAS, and PAH were determined. There is a general trend of decreasing contamination from 2010 to 2015 for the POPs included in the survey. A trend of decreasing contamination with increasing latitude shown in the 2010 moss data is confirmed in the results from 2015. The results for PCB indicate release from local sources in the Oslo area.

Monitoring of environmental contaminants in air and precipitation, annual report 2015. NILU report
This report presents results from 2015 for persistent organic pollutants (POPs) and heavy metals from the rural air- and precipitation chemistry monitoring network in Norway. These results are compared to previous years.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2015. NILU report
This report summarizes the results from the Norwegian monitoring programme on stratospheric ozone and UV radiation measurements. The ozone layer has been measured at three locations since 1979: in Oslo, Tromsø/Andøya and Ny-Ålesund. The UV measurements started in 1995. The results show that there was a significant decrease in stratospheric ozone above Norway between 1979 and 1997. After that the ozone layer stabilized at a level ~2% below the 1979-1989 average. However, there are large inter-annual variations and in 2015 the average ozone level was close to the 1979-1989 average values at all three Norwegian stations.

Air quality monitoring in the border areas of Norway and Russia - progress report April 2015-March 2016. NILU rapport
The nikkel smelters in NW Russia emit large quantities of sulphur dioxide (SO2) and heavy metals. These emissions lead to enhanced concentrations of environmental pollutants in the border areas. The monitoring program shows that air quality in Karpdalen violates Norwegian threshold values for SO2 hourly mean values in 2015, seasonal mean winter 2015/16 and hourly mean and daily mean values in 2016 (as of 31st March).

NILU's Environmental Management Report 2015. NILU OR
One of NILU's main goals is to study the impact of pollution and supply decision-makers with a sound scientific platform for choosing measures to reduce the negative impacts. Furthermore, it is very important for the institute to have control of the impact the institute¿s own activities may have on the environment and to reduce negative impacts as far as possible.
NILU has for many years been working to improve the status of the environment and to reduce negative impacts. In order to take this one step further, it was decided that the institute should restructure the work according to a relevant environmental standard and to seek certification according to the same standard.
The chosen standard is ISO 14001:2004 (Environmental management systems - Requirements with guidance for use) and NILU achieved certification according to this standard in October 2010. This report summarizes the results of the system in 2015.

Verification of stack heights for expansion of the aluminium smelter at Karmøy. NILU rapport
smelter. The model results show that the impact is in compliance with the limit values for the environment for all components except for hydrogen fluoride. The guideline for effect of hydrogen fluoride versus vegetation is exceeded in an area covering 25 km2, inclusive of the factory area and areas at sea. Impacted land area outside the plant is 11,5 km2. Emission from the roof of the production hall contributes 95 % of the total concentration within the area of exceedance.
