Dbarta24 Desk — Amidst a worsening global trend of deteriorating air quality driven by climate shifts and unstructured urban development, residents of Bangladesh’s capital have finally found a breath of fresh air.
Consecutive days of steady monsoon rain have successfully washed away persistent pollutants, pushing Dhaka—historically a staple at the apex of global pollution charts—completely out of the top 15 most polluted cities list.
According to data released on Saturday, August 1, 2026, by IQAir, a Switzerland-based air quality monitoring organization, Dhaka placed 18th globally with an Air Quality Index (AQI) score of 86.
This reading classifies the city’s current atmospheric condition as “moderate” or acceptable for the general population.
Kinshasa Claims the Top Spot as Global Hotspots Swelter
While Dhaka experiences a temporary atmospheric cleansing, other major global metropolises are grappling with highly hazardous conditions.
The Democratic Republic of Congo’s capital, Kinshasa, topped the real-time global pollution index on Saturday morning, clocking a concerning AQI score of 188.
This ranking firmly places Kinshasa’s atmosphere in the “unhealthy” bracket, posing immediate health threats to its inhabitants.
Uganda’s capital, Kampala, trailed closely in second place with an unhealthy score of 173. The rest of the top five highly polluted cities included:
-
Jakarta, Indonesia: Ranked 3rd with an AQI score of 149.
-
Dubai, United Arab Emirates: Ranked 4th with an AQI score of 149.
-
Manama, Bahrain: Ranked 5th with an AQI score of 137.
+-------------------------------------------------------------+
| GLOBAL AQI RANKINGS (AUG 1, 2026) |
+------+-----------------------+-----------+------------------+
| Rank | City, Country | AQI Score | Health Status |
+------+-----------------------+-----------+------------------+
| 1 | Kinshasa, DRC | 188 | Unhealthy |
| 2 | Kampala, Uganda | 173 | Unhealthy |
| 3 | Jakarta, Indonesia | 149 | Unhealthy* |
| 4 | Dubai, UAE | 149 | Unhealthy* |
| 5 | Manama, Bahrain | 137 | Unhealthy* |
| 18 | Dhaka, Bangladesh | 86 | Moderate |
+------+-----------------------+-----------+------------------+
*Note: Scores between 101–150 are specifically unhealthy for sensitive groups.
Understanding the AQI Metrics
The Air Quality Index operates on a standardized metric to determine health advisories worldwide:
-
0 to 50: Classified as “Good.”
-
51 to 100: Classified as “Moderate” (Dhaka’s current tier).
-
101 to 150: Considered “Unhealthy for Sensitive Groups.”
-
151 to 200: Designated as “Unhealthy” for the general public.
Global health bodies warn that when the AQI ranges between 201 and 300 (“Very Unhealthy”), children, the elderly, and individuals with respiratory conditions must limit outdoor exposure.
Any score between 301 and 400 is deemed “Hazardous,” triggering severe health warnings for the entire population of an urban zone.
Looking Forward
While the current respite offers Dhaka residents a brief break from toxic smog, environmental experts note that the improvement is largely seasonal, driven by precipitation rather than systemic structural changes.
To sustain this momentum beyond the rainy season, the city must address its core long-term pollution drivers, including rampant construction dust and industrial emissions.
