<abstract>
<p>In order to develop strategies for controlling and reducing Arctic air
pollution, there is a need to understand the basic mechanisms for
determining the fate of air pollution in the Arctic. Sources of atmospheric
particles at Station Nord (81° 36&apos; N, 16° 40&apos; W) in North East
Greenland were evaluated for a two-year period from March 2008 to February
2010. Source apportionment using Positive Matrix Factorization (PMF) and
COnstrained Physical REceptor Model (COPREM) was based on measurements of
black carbon, elements (Al, Si, S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga,
As, Se, Br, Rb, Sr, Zr, Pb) and inorganic ions (SO&lt;sub&gt;2&lt;/sub&gt;, SO&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;2&amp;minus;&lt;/sup&gt;,
Na&lt;sup&gt;+&lt;/sup&gt;, NH&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;+&lt;/sup&gt;, NO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;&amp;minus;&lt;/sup&gt;, Cl&lt;sup&gt;2&amp;minus;&lt;/sup&gt;. In general, source
apportionment results by PMF and COPREM showed good agreement. Five sources
adequately explained the measurements, which included a &lt;i&gt;Marine&lt;/i&gt; and a &lt;i&gt;Soil&lt;/i&gt; source of
natural origin and three additional anthropogenic sources, which were all
influenced by metal industries. One anthropogenic source was dominated by Zn
of which air mass back trajectories using the Hybrid Single Particle
Lagrangian Integrated Trajectory (HYSPLIT) model suggested a Canadian Arctic
origin, despite certain influences from Southern and Eastern origins.
Another anthropogenic source was characterised by high concentrations of Pb
and As, which has been historically referred to as a &lt;i&gt;Combustion&lt;/i&gt; source at Station Nord.
The impacts of large-scale industry in Siberia, Russia were evident through
high Cu concentrations in both the &lt;i&gt;Combustion&lt;/i&gt; source   and an additional &lt;i&gt;Cu/Ni&lt;/i&gt; source.
&lt;br&gt;&lt;/br&gt;
Br correlated well with the anthropogenic species S and Pb though the
elements are unlikely to have a common origin. More likely, sulphuric acid
aerosols serve as transport containers for Br species of marine origin. Of particular relevance to climate, sources of black carbon
were identified to be mainly anthropogenic and most probably of Siberian
origin (80–98%).</p>
