Preamble
In February, 2016, at the IX meeting in Kirkenes (Norway), the Norwegian-Russian expert group on ambient air monitoring in the border areas agreed to make an updated version of the joint report on ambient air pollution. The previous (first) joint report contained monitoring data from the period 2008- 2012. This new report will contain monitoring data from the period 2010 – 2015.
Like the previous report, the present report is mainly focused on ambient air pollution of sulphur dioxide
(SO2) and heavy metals – nickel (Ni) and copper (Cu) in the border area between Russia and Norway.
The joint report has been prepared by C. F. Pettersen, H. Aronsen, S. Guttu (Norwegian Environment Agency), T. F. Berglen (Norwegian Institute for Air Research – NILU), O. Chaus, T. Pavlova, A. Ustinova, and T. Korotkova (Federal State Budgetary Murmansk Administration for Hydrometeorology and Environmental Monitoring (Murmansk UGMS).

In Karpdalen, the at Svanvik typically are a factor 10 lower than in Nikel. number of episodes with concentration levels above Karpdalen has a higher annual average than Svanvik. 500 µg/m3 were at the top (n=75) during the winter in 2015/2016. A summary of the 10-minutes values Norwegian legislation on air quality has been violated are given in Table 3.3, sorted by calendar year. for the three previous years in Karpdalen (more than three days with daily mean over 125 µg/m3, and more
