Dhaka Tops Global Air Pollution Chart with ‘Very Unhealthy’ AQI Score
Dhaka has been identified as the city with the most polluted air globally, recording an Air Quality Index (AQI) score of 286, categorizing its air as ‘very unhealthy’ for the second consecutive day.
Yesterday, Dhaka’s AQI score was 257. This alarming status underscores the severe environmental challenges faced by the city’s residents, with air pollution posing significant health risks. India’s Kolkata and Mumbai, along with Pakistan’s Lahore, were ranked closely behind Dhaka, with AQI scores of 269, 240, and 211 respectively, indicating a widespread air quality crisis across several major South Asian cities.
The AQI scale reveals that values between 201 and 300 signify ‘very unhealthy’ air quality, directly impacting public health. This range indicates a high risk of adverse health effects, urging residents, especially those in vulnerable groups, to take necessary precautions. Defined by the concentration of five major air pollutants — particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone — the AQI serves as a crucial tool for informing the public about daily air pollution levels and potential health implications.
Historically, Dhaka has struggled with persistent air pollution, experiencing the worst conditions during the winter months. Conversely, air quality sees relative improvement with the onset of the monsoon season, illustrating the seasonal dynamics of the city’s environmental health challenges.
Leaders of the quota reform movement have resolutely refused to negotiate with the government, insisting that their movement will persist until their demands are met.
In a Facebook post, Hasnat Abdullah, a coordinator of the movement, declared, “No discussion through stepping onto blood.”
Asif Mahmud, another prominent leader, echoed this sentiment, stating, “There can be no dialogue with bullets. I would prefer death over this betrayal.”
He further elaborated, “On one side, there are bullets. On the other, there is a call for dialogue. We can’t sit for dialogue while stepping onto the blood of our brothers.”
Earlier, leaders of the quota reform movement accused the government of escalating the law and order situation towards violence, asserting that their movement was peaceful until the government’s intervention.
Vowing to continue their struggle, Asif Mahmud stated, “We will continue our protests till we achieve our demands for reformation of the quota system, reopening of the halls and campuses, making university campuses terror-free, withdrawing political forces from the campuses, and punishing the killers and attackers.”
He added, “The people of the country have encircled those who tried to corner us. No conspiracy will be able to derail our movement.”
Prime Minister Sheikh Hasina today urged both local and international investors to invest in the extraction of marine resources from Bangladesh’s extensive sea areas.
“In order to fortify the blue economy through the diverse utilization of our marine resources, I call upon local and foreign investors to seize the opportunity to invest in Bangladesh. This will enable us to harness more of our marine resources,” she announced.
The Prime Minister made these remarks during the inauguration of the Bangladesh International Aquaculture and Seafood Show-2024 at the Bangabandhu International Conference Centre (BICC) in Dhaka.
She emphasized the importance of adhering to proper standards in the collection, distribution, and processing of fish to boost exports, aiming to make fish the country’s second-largest source of foreign currency.
Sheikh Hasina pointed out that her government has made limited progress in harvesting fish and other sea resources from the deep sea due to a lack of interest from local investors.
“Therefore, we need foreign investment to advance in this area. This is the reality we must face,” she noted.
She also suggested that both local and foreign investors can collaborate in joint ventures or invest separately in this sector to achieve better results.
