With the air quality index score in Bangladesh's capital, Dhaka, reaching 156, it has been ranked ninth on the list of cities with the worst air quality worldwide. The situation is further exacerbated by the ongoing heat wave, making air pollution a major concern for the city's residents. This issue is not only limited to Dhaka, as many other cities in South Asia, including India's Delhi and Pakistan's Lahore, are also facing dangerously high levels of air pollution, leading to potential health hazards. This highlights the urgent need for addressing air pollution and its impacts on public health.
Dhaka's Air Quality: A Looming Health Crisis
Background
Air pollution has emerged as a severe threat to public health in Bangladesh, particularly in the densely populated capital city of Dhaka. The city's air quality index (AQI) has consistently ranked among the worst worldwide, with levels of particulate matter (PM) and other pollutants exceeding recommended limits.
Current Situation
Recent data from Google indicates that Dhaka's AQI has reached 156, placing it among the nine cities with the poorest air quality globally. This alarming level is attributed to a combination of factors, including:
Health Impacts
Exposure to air pollution poses significant risks to human health. Particulate matter can penetrate deep into the lungs, causing respiratory issues such as asthma, bronchitis, and lung cancer. Other pollutants, including sulfur dioxide and nitrogen oxides, can irritate the airways and contribute to cardiovascular diseases.
Ongoing Heat Wave
The ongoing heat wave in Bangladesh has further worsened Dhaka's air quality. High temperatures trap pollutants close to the ground, exacerbating respiratory problems. The heat index, which combines temperature and humidity, has been exceeding dangerous levels in recent weeks.
South Asian Air Pollution Crisis
Dhaka's air pollution problem is not isolated. Many other cities in South Asia, including New Delhi, Lahore, and Karachi, are also facing dangerously high levels of pollution. This region is considered one of the most polluted in the world, with significant health consequences for its inhabitants.
