Air Quality Index (AQI) in Mauritania 🇲🇷

Live Air Quality Index (AQI) and PM2.5 Levels in Mauritania

Currently, the Air Quality Index (AQI) in Nouakchott, the capital of Mauritania, is measured at a score of 71. According to the US EPA health standard, this air quality rating is categorized as Moderate. The current atmosphere in Nouakchott is influenced by a PM2.5 (fine particulate matter) concentration of 19.6 µg/m³ and PM10 levels recorded at 54.2 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 0.4 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Mauritania based on industrial output, traffic density, and local weather patterns. Real-time pollution data and respiratory health alerts are also being actively monitored in cities like Nouadhibou, Kiffa, Dar Naim and Néma. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.

Air Quality Snapshot: Mauritania Right Now

Across 5 monitored cities in Mauritania, live air quality currently ranges from a low of 31 AQI in Kiffa (the cleanest air right now) to a high of 184 AQI in Nouadhibou (the most polluted). By US EPA health band, the nationwide distribution stands at 2 Good, 2 Moderate, 1 Unhealthy. The average fine-particulate (PM2.5) concentration across these cities is 31.1 µg/m³ — approximately 6.2 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Air Quality in Mauritania — FAQ

Common questions about AQI levels, pollutants, and data sources for Mauritania.

What is the current air quality in Mauritania?

Live AQI readings for 5 city(ies) across Mauritania are listed above on the US EPA 0-500 scale.

Where does Mauritania's AQI data come from?

Real-time readings come from ground-based monitoring stations operated by national environmental agencies in Mauritania, delivered via WeatherAPI.com and aggregated using the EPA AQI formula.

What is a healthy AQI value in Mauritania?

On the EPA scale used worldwide, 0-50 is Good, 51-100 is Moderate, 101-150 is Unhealthy for sensitive groups, 151-200 is Unhealthy, 201-300 is Very Unhealthy, and 301-500 is Hazardous. The WHO 24-hour PM2.5 guideline is 15 μg/m³.

Why do AQI readings vary between cities in Mauritania?

Air quality is highly local — major pollution sources (traffic, industry, dust, wildfires) cluster around cities, while wind direction and topography move them around. Comparing nearby readings on this page is the best way to see how conditions change across Mauritania.
