The Department of Environment has issued a public information procedure concerning ozone pollution, as the ozone threshold of 180 µg/m3 is likely to be reached on Monday, August 21, 2023. The growth in ozone pollution results from the sun's action on certain automotive and industrial pollutants. This effect is amplified by the intensity of sunlight and low wind conditions.
Due to persistent high temperatures and weak winds, which are unfavorable for the dispersion of emitted pollutants, the Government has issued several recommendations to reduce pollutants in the atmosphere:
For vulnerable populations such as pregnant women, infants and young children, people over 65, those with cardiovascular issues, heart or respiratory insufficiency, or asthma, the following is advised:
- Limit outdoor intense physical and sports activities; indoor activities may continue.
- Avoid outings during the hottest hours.
- Opt for shorter and less strenuous outings.
- Seek advice from a pharmacist or consult a doctor if respiratory or cardiac discomfort is experienced.
Recommendations for Road Users:
- Prefer non-polluting modes of transport for short journeys.
- Limit private and professional car use by utilizing public transportation and carpooling.
- Avoid travel on major roadways and nearby areas during peak hours.
- Postpone maintenance or cleaning work requiring solvents, paints, varnishes, etc.
Air quality in the Principality is continuously monitored through an automated network of five measurement stations located at various points. These stations measure pollutants such as nitrogen oxides, sulfur dioxide, carbon monoxide, dust, and ozone (O3). The collected data are analyzed daily by the Department of Environment.
As the risk of ozone pollution increases amid ongoing high temperatures, residents are encouraged to follow these guidelines to minimize health risks and environmental impacts. The situation underscores the importance of collective responsibility in preserving air quality and public health.
