<i>Air pollution</i>
It is a matter of great concern that the quality of the air of the big cities of our country is deteriorating at an alarming pace. Fumes from the industries, vehicular emissions, smoke from the brickfields--all contribute to the degradation of the quality of air. According to a study the amount of lead in Dhaka's air is 463 nanograms per cubic meter---the highest in the world. The very smell of the city's air is sickening--to say the least. It is the rapid growth of population that is also responsible for the deterioration of air quality. The amount of carbon-dioxide, carbon- monoxide and sulphur-dioxide in the air is increasing rapidly. It is needless to say that this trend is worrisome. A few years ago the government banned the vehicles run by two -stroke engines. Certainly, it was a wise move. More efforts are required to address the menace of air pollution.
