Due to persistent high temperatures and low winds this summer, the Prince’s Government has issued a number of recommendations to residents in the face of elevated ozone levels. However, the most recent data, from Promenade des Anglais in Nice on August 6, shows ‘moderate’ ozone levels with an AQI score of 59, well below the level that should cause concerns to the majority of people.

The Principality is aligned with objectives set by European Directives, the Government said in a press release. When the ozone threshold of 180 μg/m3 of air is exceeded, the Directorate of the Environment informs the population.

Ozone pollution results from the action of the sun on certain automotive and industrial pollutants. It grows with the intensity of the sun and when the winds are weak. The maximum concentrations are most often observed in summer and in areas that may be far from the actual sources of pollution.

Air quality in the Principality is monitored by an automated network of five measuring stations: Rue Grimaldi, Boulevard Charles III, Place des Moulins, Fontvieille and Quai Antoine 1er.

Air pollutants such as nitrogen oxides, sulphur dioxide, carbon monoxide, dust and ozone are measured continuously.
