The road users in Dhaka city frequently complain about headache, eye and skin irritation and breathing problem. The research has find out that the situation is expected to be worsening further with the increase of population, economic development and high influx of people from rural areas to urbanized Dhaka. Motor vehicle is increasing at 5% per year in Dhaka, which is the most significant source of air pollution. The paper has analyzed the vehicular population structure and trends in Dhaka from 1990 to 2000 along with the role of different types of motor vehicle in this trends. The analysis show that 2-wheeler vehicle, car and taxi and 3-wheeler occupied 45, 22 and 12% respectively in 1992; while those were 38, 26 and 16% respectively in 2000. It is observed from the results that total NOX (Oxides of Nitrogen) emission in 2000 was 31903 tones and among them 3-wheeler vehicles, diesel trucks, and cars and taxis respectively contributed 44, 33 and 11%, while the total SOX (Oxides of Sulfur) emission was 19386 tones; and emitted by 58% and 17% from diesel truck, and car and taxi respectively. Finally, the research recommends several strategies for vehicular emission control with the aim of improving existing air quality in Dhaka. |
