Dhaka, July 2 – On Thursday morning, Dhaka was tied for first place along with Kinshasa, the capital city of the Democratic Republic of the Congo, as one of the most polluted places globally, achieving an Air Quality Index (AQI) reading of 152 at 9:25 am.
The city's air quality was rated as "Unhealthy," suggesting that levels of harmful particles in the air had risen to a point where they might endanger people's well-being, based on the AQI index.
Delhi came second with an AQI reading of 145, then Jakarta at 132. Jerusalem placed fourth with an AQI value of 107.
As per AQI guidelines, values ranging from 101 to 150 are classified as "unhealthy for vulnerable populations," 151 to 200 as "unhealthy," 201 to 300 as "highly unhealthy," and readings exceeding 301 are categorized as "dangerous," indicating significant threats to well-being.
The Air Quality Index offers daily information about air conditions, showing whether the air is pure or contaminated and pointing out possible effects on health.
In Bangladesh, the Air Quality Index (AQI) is determined using five key contaminants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone.
Dhaka has faced ongoing issues with air pollution, as environmental conditions tend to deteriorate in the colder months and improve when the rainy season arrives.
According to the World Health Organization, air pollution leads to approximately seven million fatalities worldwide annually, primarily because of conditions such as stroke, cardiovascular diseases, chronic obstructive pulmonary disorder, lung cancer, and acute respiratory illnesses.
