Dhaka's air quality continued to remain 'unhealthy for sensitive groups' on Tuesday despite intermittent late monsoon drizzle a day before. With an air quality index (AQI) score of 132 at 9am, the metropolis ranked 9th in the list of world cities with the worst air quality. The United Arab Emirates’ Dubai, Pakistan’s Lahore and Karachi occupied the first three spots, with AQI scores of 196, 196 and 154, respectively. An AQI between 101 and 200 is considered 'unhealthy', particularly for sensitive groups. Similarly, an AQI between 201 and 300 is said to be 'poor', while a reading of 301 to 400 is considered 'hazardous', posing serious health risks to residents. Also read: Dhaka’s air turns ‘unhealthy for sensitive groups’ AQI, an index for reporting daily air quality, is used by government agencies to inform people how clean or polluted the air of a certain city is, and what associated health effects might be a concern for them. In Bangladesh, the AQI is based on five criteria pollutants -- Particulate Matter (PM10 and PM2.5), NO2, CO, SO2 and Ozone. Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon. With the advent of winter, the city’s air quality starts deteriorating sharply due to the massive discharge of pollutant particles from construction work, rundown roads, brick kilns and other sources. Air pollution consistently ranks among the top risk factors for death and disability worldwide. Breathing polluted air has long been recognised as increasing a person’s chances of developing a heart disease, chronic respiratory diseases, lung infections and cancer, according to several studies. Also read: Dhaka’s air quality turns ‘moderate’ As per the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.

Residents of Faridpur and Patuakhali woke up to a wet spell on Wednesday morning, as Asani weakened into a cyclonic storm and triggered intermittent overnight drizzle. The first drops of rain in the two districts came with a cool breeze, bringing the much-needed reprieve to the residents from the sizzling summer heat. Surujul Amin, in-charge of the Faridpur weather office, said the partly cloudy sky in the morning and the drizzle were due to Asani weakening into a cyclonic storm.
