Causes and Health Impacts
Experts consistently point to brick kilns, vehicle emissions, and dust from construction sites as the primary culprits behind Dhaka’s air pollution.
This severe contamination poses a serious health risk, affecting people of all ages.
Air pollution is particularly detrimental to children, the sick, the elderly, and pregnant women.
Urban planner Professor Dr. Adil Mohammad Khan commented, "Dhaka's air pollution has been consistently alarming.
Among the many sources of air pollution, construction activities have recently become prominent.
