Latest News About Air Quality Index

I don’t have live access to current air quality data right now, but I can point you to reliable sources for the latest AQI updates and how to interpret them.

Key sources for latest air quality index

How to read AQI categories (brief)

• 0-50 Good: Air quality is satisfactory; low health risk for the general population.
• 51-100 Moderate: Acceptable; some people, especially sensitive individuals, may experience minor effects.
• 101-150 Unhealthy for Sensitive Groups: Affects people with respiratory or heart conditions, older adults, and children more than the general public.
• 151-200 Unhealthy: Everyone may begin to experience health effects; sensitive groups may experience more serious effects.
• 201-300 Very Unhealthy: Health warnings of emergency conditions; outdoor activities should be limited.
• 300+ Hazardous: Serious health effects possible; avoid outdoor exertion.

If you tell me your city or region (e.g., Marseille or a nearby area), I can give you a concise interpretation likely to apply there and help you plan outdoor activities today.
