(5) Air Pollution in Bangladesh: Main Sources

By a Staff Reporter

Dhaka, [date]: Air pollution has become a serious threat to public health in Bangladesh, especially in the big cities. Experts identify the following main sources.

1. Vehicle emissions: Old and poorly maintained vehicles release smoke full of harmful gases and fine particles.
2. Brick kilns: Many kilns around cities burn coal and wood in outdated ways and pour smoke into the air.
3. Construction dust: Unprotected construction work and unpaved or broken roads produce huge amounts of dust.
4. Industrial emissions: Mills and factories discharge smoke and chemicals, often without proper filters.
5. Waste burning: Open burning of household and industrial waste adds toxic fumes.
6. Other sources: Cooking with biomass fuel in households and burning of crop residue also contribute.

The pollution causes asthma, lung disease and other illnesses, and it harms the environment. Experts urge the authorities to enforce emission standards, modernise brick kilns, cover construction sites and plant more trees.
