Gradual adoption of greener fuels for transport vehicles over the last one decade is showing a prospect of reducing air pollution in the city, according to an expert, reports UNB.
Addressing a seminar on 'Air and Water Pollution Aspects of Bangladesh,' they suggested that steps should be taken to accelerate the change of fuels to achieve further improvement in the air condition.
The Chemical Engineering Division of Institution of Engineers, Bangladesh (IE,B) organised the seminar in the city Saturday.
Dil Afroza Begum, professor of Chemical Engineering Department of Bangladesh University of Engineering and Technology (Buet), in her keynote speech showed that the presence of carbon monoxide (CO) in the air of Mohakhali in the capital has come down from 8,000 ppm (parts per million) to 2,500 ppm between 2001 and 2010.
The presence of CO in the air of Moghbazar and Sonargaon intersection areas has dropped down proportionately during the same period, she said referring to a study on 'Impact of Regional Cooperation on Reduction and Air and Water Pollution Level of Dhaka City.'
Dil Afroza Begum noted that the reduction in CO and other pollutants in the air of Dhaka city has been taking place because of gradual change of fuel in transport vehicles.
She also recommended that air pollution could be further reduced if the traffic congestion in the capital is mitigated.
If the vehicles can ply roads with a speed over 30 km per hour most of the time, the emission of CO and hydrocarbons can be reduced to a great extent, she said.
Simultaneously, she said, the use of better petroleum products must be increased.
