The air quality is expected to meet EU limit values in this location

Nitrogen dioxide pollution

NO2 (nitrogen dioxide) annual mean level is 35.4 µg/m³, which is below EU quality limit set to 40 µg/m³.

Increased levels of nitrogen dioxide can have significant impacts on people with asthma because it can cause more frequent and more intense attacks. Children with asthma and older people with heart disease are most at risk.

Particulate matter pollution

PM10 (10 micrometre particulate matter) annual mean level is 21.7 µg/m³, which is below EU quality limit set to 40 µg/m³.

PM2.5 (2.5 micrometre particulate matter) annual mean level is 13.1 µg/m³, which is below EU quality limit set to 25 µg/m³.

PM10d (days exceeding daily PM10 mean limit of 50 µg/m³) is approximately 6 days pear year, which is below the quality limit set to 35 days per year.

PM2.5 and PM10 are atmospheric particulate matter with a diameter smaller than respectively 10, 2.5 microns. They are also called floating dust. Long-term exposure to increased levels of PM2.5 and PM10 may trigger or worsen chronic diseases such as asthma, heart attack, bronchitis and other respiratory problems.
