On a Monday morning in Dhaka, the air carried a quiet reassurance — an AQI of 76 placed the city in the moderate range, 26th among the world's most polluted, yet far from the hazardous readings choking cities like Lahore and Jakarta. It is a moment that invites neither celebration nor alarm, but rather the kind of measured vigilance that urban life in a warming, industrializing world increasingly demands. The numbers are a reminder that air — invisible, shared, and unequal in its burdens — is never simply background.
Dhaka's air quality moderate as capital ranks 26th globally in pollution
The air was breathable, though not pristine.

Why does Dhaka rank 26th globally when the reading seems relatively safe?
Mimi
Because 26th out of the world's most polluted cities means there are still 25 places worse. The scale is global, and many cities in South Asia and beyond are dealing with far more severe pollution. Dhaka's moderate reading is actually better than its neighbors.
Mark
What's the practical difference between a score of 76 and, say, 150?
Mimi
At 76, most people can go about their day normally. At 150, you're in unhealthy territory for anyone with respiratory sensitivity—children, elderly people, those with asthma. The air itself becomes a factor in your daily decisions.
Mark
Why does the index measure those five specific pollutants?
Mimi
They're the ones that accumulate in cities—from vehicles, industry, power plants, construction. They're what you actually breathe in and what settles in your lungs over time. They're measurable and they correlate with health outcomes.
Mark
If Dhaka is moderate, why should anyone care about this reading?
Mimi
Because moderate today doesn't mean moderate tomorrow. These readings change with seasons, with traffic patterns, with weather. And even moderate air quality, sustained over years, has health effects. The point is to watch the trend, not just celebrate a single good day.
Mark
What would push Dhaka's score higher?
Mimi
Anything that increases those five pollutants—more vehicle emissions during rush hour, dust from construction, industrial output, weather patterns that trap air over the city instead of dispersing it. A single day's reading is a snapshot, not a forecast.
El Pulso
- Dhaka's AQI of 76 at 9am signals breathable but imperfect air, placing the city 26th globally — a ranking that is neither a crisis nor a clean bill of health.
- Lahore, Jakarta, and Kuching sit at the sharp end of the global pollution table, with scores above 176 pushing into territory where the air itself becomes a medical concern for millions.
- The gap between Dhaka's moderate reading and the hazardous threshold of 301 is wide, but the city remains on a watchlist — a place where the atmosphere is something to be tracked, not taken for granted.
- Bangladesh monitors five key pollutants including PM2.5 and PM10, the fine particles most capable of penetrating deep into the lungs and accumulating harm over time.
- For Dhaka's residents, a score of 76 meant ordinary life could proceed — commutes, school runs, errands — without immediate precaution, though the underlying conditions that put the city on the list at all have not disappeared.
On a Monday morning in Dhaka, the air carried a quiet reassurance — an AQI of 76 placed the city in the moderate range, 26th among the world's most polluted, yet far from the hazardous readings choking cities like Lahore and Jakarta. It is a moment that invites neither celebration nor alarm, but rather the kind of measured vigilance that urban life in a warming, industrializing world increasingly demands. The numbers are a reminder that air — invisible, shared, and unequal in its burdens — is never simply background.
Monday morning in Dhaka offered a modest reassurance: the Air Quality Index read 76 at nine o'clock, a moderate score that placed the capital 26th on the global list of most polluted cities. It was not a pristine reading, but it was a livable one — the kind of air that allows a city to move through its day without immediate alarm.
The contrast with other regional cities was stark. Lahore topped the global rankings at 183, followed by Jakarta at 177 and Kuching at 176. These were readings in the unhealthy range, where the air poses real risks to children, the elderly, and anyone with respiratory or cardiac conditions. The distance between Dhaka's 76 and Lahore's 183 was not merely numerical — it represented a meaningful difference in the daily burden carried by human bodies.
The AQI scale itself tells a layered story. Scores between 50 and 100 are deemed moderate — acceptable, though that word carries its own ambiguities. Above 150, the air becomes unhealthy for everyone. Above 301, it is hazardous, demanding urgent intervention. Bangladesh tracks five pollutants to arrive at its daily figure: PM2.5, PM10, nitrogen dioxide, carbon monoxide, sulphur dioxide, and ozone — the slow accumulations that, over time and in sufficient concentration, exact a toll on health.
For Dhaka's residents, a reading of 76 meant the city was not in crisis. People could commute, study, and go about their lives without special precaution. But the city remained on the list — a place where the air is watched, where the numbers can shift, and where the atmosphere itself is never quite background noise.
On Monday morning in Dhaka, the air was breathable. At nine o'clock, the Air Quality Index registered 76—a score that falls squarely in the moderate range, the kind of reading that means you can go outside without immediate concern, though the air is not pristine. It was enough to place the capital 26th on the global list of most polluted cities, a ranking that, while not enviable, offered some perspective on where things stood.
Three cities ranked worse. Lahore, across the border in Pakistan, topped the list with an AQI of 183. Jakarta, Indonesia's sprawling capital, followed at 177. Kuching, in Malaysian Borneo, came third at 176. These were not moderate readings. They were in the territory where the air itself becomes a health concern, especially for children, the elderly, and anyone with respiratory conditions. The gap between Dhaka's 76 and Lahore's 183 was substantial—a difference measured not just in numbers but in the actual burden placed on lungs and bodies.
The Air Quality Index itself is a daily snapshot, a single number meant to tell you something simple: how clean is the air you're breathing right now, and what might it do to you? The scale runs from pristine to dangerous. A score between 50 and 100 is moderate—acceptable, the authorities say, though "acceptable" is a word worth questioning. Between 101 and 150, the air becomes unhealthy for sensitive groups: pregnant women, children, people with asthma or heart disease. From 151 to 200, it crosses into outright unhealthy territory for everyone. At 201 to 300, the air is very unhealthy. Anything above 301 is hazardous, the kind of air that poses serious health risks to the general population, not just the vulnerable.
Dhaka's measurement of 76 meant the city was nowhere near those worst categories. But the index itself depends on what you measure. In Bangladesh, officials track five major pollutants: particulate matter in two sizes—PM10 and the finer PM2.5—along with nitrogen dioxide, carbon monoxide, sulphur dioxide, and ozone. These are the substances that accumulate in the air, that settle in your lungs, that over time and in high enough concentrations can damage health. On this particular Monday morning, the combination of all five had produced a moderate reading.
What the number 76 actually meant for the people living in Dhaka was less abstract than the scale suggests. It meant the air was acceptable enough that most people could move through the city without special precautions. It meant that if you had to be outside—commuting to work, running errands, going to school—you were not facing an immediate crisis. But it also meant that Dhaka remained on a global list of cities where air quality was a concern, where the atmosphere itself was something to monitor, something that could shift, something that required attention.
