Dhaka City has been grappling with air pollution for the past few years, with media consistently reporting that it often tops the list of cities worldwide with the worst air quality. Many researchers think that the capital is now becoming uninhabitable as human health is susceptible to various diseases due to environmental factors.
According to the air quality index (AQI) monitored by the organisation IQ Air last year, Dhaka ranked as the most polluted capital city, with AQI scores exceeding 300 multiple times. The AQI scores for the first and second days of this year were 244 and 256, respectively. An AQI score between 201 and 300 indicates very unhealthy air quality, with higher scores reflecting more severe pollution levels. "Very unhealthy" signifies that the air quality poses significant health risks, potentially leading to serious health issues with prolonged exposure.
While specific data on deaths due to air pollution in our country is lacking, researchers, doctors and observers think that the nation's severe air pollution is a leading cause of numerous diseases and fatalities.
Public awareness campaigns are crucial to combat these health issues arising out of air pollution. Measures such as reducing fossil fuel consumption, curbing black smoke emissions, promoting afforestation to counter deforestation, preventing littering and tobacco use and minimising dust generation during construction activities are essential steps to improve air quality and public health.
Various laws and regulations are being discussed by the government to mitigate and prevent air pollution, but both governmental and private initiatives are crucial in addressing this issue. Ignorance of the people and irregularities of different kinds are a major problem. Urgent action is needed to tackle this pressing issue, otherwise air pollution would become a leading cause of death. It is not solely the responsibility of the government or environmental organizations, citizens must also be proactive in safeguarding the environment.
