The largest source of emissions of particles is the energy and transport sector, which, in 2010, accounted for 73% of the emissions, followed by the industrial processes sector (18%).
In 2010, emissions of particles less than 10 µm diameter (PM10) and less than 2.5 µm diameter (PM2.5) were about 44,000 and 31,500 tonnes, respectively.
Results from studies on effects of studded tyres on road surface wear show a substantial increase in emitted particles. These sources which are included under the transport sector are responsible for about 20% of the total emissions.

Correlation between particles in air and mortality
Studies have established a correlation between exposure to air pollution particles and human mortality at concentrations of particles currently found in cities. The adverse effects of pollution particles are the most prominent in elderly people and those with heart and lung diseases.
