Dhaka 3rd most polluted city in the world this morning
Dhaka’s Air Quality Falls Into Sensitive-Group Warning Range
Bdbusinessdaily.com – Dhaka began the day among the world’s most polluted major cities, placing third in the global air-quality ranking at 9:15am with an Air Quality Index score of 129. The reading put the Bangladeshi capital in the category described as unhealthy for sensitive groups, a level at which some residents may need to take extra precautions outdoors.
Kuching in Malaysia held the highest pollution reading in the ranking, with an AQI of 191, while Indonesia’s Jakarta was second at 167. Both cities recorded worse air-quality conditions than Dhaka at the time of the assessment.
What an AQI Score of 129 Means
The Air Quality Index is designed to give the public a simple indication of how clean or polluted the air is on a particular day and what health effects may be linked to the measured pollution level. Higher scores indicate greater concern.
A score from 50 to 100 is classified as moderate. Air quality in that range is generally acceptable, though people who are unusually sensitive to pollution may experience minor effects and may wish to avoid extended, strenuous activity outside.
Readings from 101 to 150, the range in which Dhaka was placed, are considered unhealthy for sensitive groups. Children, older adults, and people with respiratory or heart conditions may be more likely to feel the effects of polluted air. Reducing long periods of heavy outdoor exertion can be a sensible precaution when conditions remain in this range.
The risk increases as the index rises. AQI scores between 151 and 200 are classified as unhealthy. A level from 201 to 300 is regarded as very unhealthy, while any figure above 301 is considered hazardous and may present serious health risks across the population.
Pollutants Measured in Bangladesh
Bangladesh calculates its AQI using five major air pollutants. These include particulate matter known as PM10 and PM2.5, nitrogen dioxide, carbon monoxide, sulphur dioxide, and ozone. Fine particles are particularly important in air-quality monitoring because they can remain suspended in the air and can be inhaled deeply into the respiratory system.
Daily AQI updates can help residents make practical decisions about outdoor routines. On poorer-air days, sensitive people may choose to shorten outdoor exercise, limit exposure during strenuous activity, or remain attentive to symptoms such as breathing discomfort. The index does not replace medical advice, but it offers a widely used public-health guide for understanding changing environmental conditions.
A Persistent Seasonal Challenge
Air pollution has remained a long-running concern in Dhaka. Conditions often deteriorate during the winter months, when weather patterns can contribute to the buildup of pollutants in the atmosphere. Air quality commonly improves after the monsoon season arrives, as rainfall and changing conditions help clear particles from the air.
That seasonal cycle makes regular monitoring especially valuable for city residents. A single AQI reading reflects conditions at a particular time rather than a permanent description of the city’s air, yet repeated periods of poor air quality underline the broader challenge facing densely populated urban areas.
The health implications extend well beyond temporary irritation or reduced comfort outdoors. The World Health Organization estimates that air pollution contributes to around seven million deaths globally each year. Major health outcomes associated with pollution exposure include stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.
For Dhaka, the morning ranking offered another reminder that air quality is not only an environmental issue but also a daily quality-of-life and public-health concern. An AQI of 129 does not mean every resident will experience immediate symptoms, but it signals conditions that warrant greater care for people most vulnerable to air pollution.
Residents can use AQI readings as a practical reference throughout the day, particularly when planning travel, work, exercise, or time with children outdoors. As pollution levels shift with weather, traffic, industrial activity, and seasonal conditions, keeping track of the index can help people better understand the air around them and adjust their routines when needed.
