Dhaka, the bustling capital of Bangladesh, has been experiencing rainfall since early morning. This weather change has led to an interesting shift in air quality. On Wednesday morning, the city’s Air Quality Index (AQI) registered a score of 44, ranking it 84th among cities globally for air pollution.
According to the AQI, air quality in Dhaka was classified as ‘good’ on Wednesday, which means it poses little or no risk to health. Just the day before, the air quality was rated as healthy. Generally, an AQI score between 50 and 100 is labeled ‘moderate,’ warning sensitive individuals to limit outdoor activities. Scores above that can signal increasingly dangerous conditions.
For perspective, Lahore tops the list with an AQI of 160, followed by Delhi at 153 and Dubai also at 153. This highlights a significant challenge many cities face regarding air pollution.
The AQI measures five main pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. During winter, Dhaka often suffers from poor air quality, while the monsoon typically brings improvement.
Historically, air pollution has been a persistent issue in Dhaka. According to the World Health Organization, air pollution is responsible for approximately seven million deaths worldwide each year, primarily from heart disease, lung cancer, and respiratory infections. This statistic emphasizes the critical need for awareness and action regarding air quality.
Social media users frequently express their concerns about air quality in cities like Dhaka, sharing personal experiences and health impacts. These conversations can spark community interest in local air quality initiatives and government policies aimed at reducing pollution.
For further information on air quality and its implications, check reliable resources such as the [World Health Organization](https://www.who.int) or local environmental agencies, which provide detailed updates and recommendations.
