We all breathe over 11,000 Liters of air each day. Often
this air, known as ambient air, is polluted with
particles or gases that are unhealthy for our health.
Children breathe more air per kilogram of body weight.
The elderly people with heart and/or lung disease when
breathe polluted air, may develop more serious
respiratory problems. These two groups of humans are
relatively more susceptible to air pollution. Air
pollution can also damage our living environment
including plants and animals, change weather and reduce
visibility due to the presence of “ black carbon
pollution” in air.
Bangladesh is one of the most densely populated
countries in the world and its urban areas suffer from
air pollution of different levels and it is extremely
high in the Dhaka city where the population is about 12
million in 300 km2 of surface area. It has been
estimated that air pollution is causing about 15,000
premature deaths and several million cases of illness
every year, in the Dhaka city alone.
