PAH measurements in air and moss around selected industrial sites in Norway 2015. NILU report
On request from the Norwegian Environment Agency a pilot study of atmospheric deposition of PAH around industrial enterprises in Norway has been carried out. The participation was voluntary and 10 industries located at 10 different sites financed their own participation. The survey is based on analysis of samples of naturally growing moss collected around the enterprises during the summer of 2015. In addition, passive air samplers for collection of volatile PAH were placed around 6 of the participating enterprises. Generally, the PAH level determined in moss collected around industrial sites were considerably higher than the PAH level found in moss collected at background sites. The levels of PAHs found in the air samples was low and often at the same level as found at the closest background site, for all out of two sites, i.e. Sunndal and Kristiansand. There is no clear indication that the industry is the only source to the levels of PAHs in moss. Hence, results from this pilot study, illustrates that moss and air samples together provide a more comprehensive information regarding the spatial distribution of PAH around the industrial sites.

Air quality in Norwegian cities in 2015. Evaluation report for NBV main results. NILU report
This report documents the final deliveries of the first phase of development of the Norwegian Air Quality Planning Tool, also called ¿Nasjonalt Beregningsverktøy¿ or NBV. The main purpose of NBV is to provide a common methodological and information platform for local air quality modelling applications. The system is addressed to local and regional environmental authorities, air quality experts and consulting companies. It is intended to help them meet the requirements of current air quality legislation, to support local air quality planning and facilitate air quality good practices where people live.
The report constitutes a comprehensive user guide for the NBV services available at http://www.luftkvalitet-nbv.no. It presents each of the different products developed at NBV, documents how the product has been calculated, provides recommendations on how best to use it for planning purposes and explains the main strengths and limitations of each product. The report also includes an extensive validation of the air quality information currently available at NBV.
