Abstract

The map shows the interpolated annual average of PM2.5 in the Alpine Space area in 2012. As the map shows interpolated data primarily from background stations, the picture may be different if industrial and traffic stations were included. Due to the interpolation, local hotspots of particle pollution caused by domestic heating with wood are not shown but frequently occur in the Alpine region. Particulate matter (PM) is dust suspended in air and is categorised according to the size of particles: below 10 μm (PM10) or below 2.5 μm (PM2.5). The particles originate from different sources. Depending on the sources, they are composed of different components, such as elemental carbon, heavy metals, polynuclear aromatic hydrocarbons, sulphate, ammonia, nitrate and many others. Due to their size, the particles stay in the atmosphere for a certain time instead of sinking immediately to the ground. PM enters the human body mainly via respiration. The most important health effects of PM are on the respiratory and cardiovascular systems, an increase of cardiac infarction and inflammatory reactions (EEA 2013). The interpolation shows PM2.5 exceedances to the EU annual threshold of 25 μg/m³ mainly at the southern borders of the Alpine Convention area as well as in background stations within the southern area.
