Dhaka’s Air Quality Improves After Torrential Rain: What It Means for Residents

Heavy rain hit Dhaka early Monday, bringing some relief to the city’s notorious air pollution. Surprisingly, at around 9:25 AM, Dhaka registered an Air Quality Index (AQI) score of 42, placing it 61st among cities worldwide for air quality. This rating falls into the ‘good’ category, which suggests healthy air for residents.

The AQI scale helps people understand air pollution levels. A score between 50 and 100 indicates ‘moderate’ air quality, meaning sensitive individuals should be cautious. Scores from 101 to 150 are labeled ‘unhealthy for sensitive groups,’ while anything above 150 raises greater concerns. For instance, cities like Lahore, Kolkata, and Jakarta topped the list with AQIs of 169, 163, and 140, respectively, highlighting ongoing air quality struggles in these urban centers.

Bangladesh’s AQI is determined by monitoring five main pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. Historically, Dhaka’s air quality deteriorates in winter months but improves during the rainy season.

According to the World Health Organization, air pollution is a serious global issue, responsible for around seven million deaths each year. This is often due to heart disease, strokes, and respiratory infections. Experts stress the importance of addressing pollution, especially in densely populated cities like Dhaka, where the health risks can’t be ignored.

Recent trends on social media reveal growing public concern about air quality, with many residents sharing their frustrations and tips for staying safe during poor air days. As weather patterns shift and urban development continues, maintaining good air quality in Dhaka remains a challenge.
