Our Common Future, Chapter 9: The Urban Challenge From A/42/427. Don’t stop at pollution in dhaka city essay 7Bangladesh has yet to be implemented a National Air Quality Standard, there are no detail air quality regulations based on which Environmental Impact Assessment could be done. Very few works have been done on air quality measurements and national air pollutants estimates in Bangladesh. Author is willing to extend his assistance in doing any projects related to road traffic pollution in Bangladesh. Few recommendations are:The International Atomic Energy Agency (IAEA) stated in its News Briefs (Bangladesh studies pollution levels. IAEA News briefs. Volume 11, No. 4(73), November/December 1996: 11) that pollution levels of lead in Bangladesh are among the world’s highest during dry season, according Dr. M. Khaliquzzaman, a chief scientific officer of Bangladesh Atomic Energy Commission (BAEC), with levels falling during periods of medium and heavy rainfall. Dr. Khaliquzzaman attributed the high lead levels to the use of leaded fuel in vehicles. He said that lead poses a public health danger, especially to children, by penetrating the lungs and entering the blood stream, and can lead to impaired intelligence.Air pollution in Dhaka is serious due to increasing population and associated motorization. Although existing air quality monitoring data is limited, it has been clearly shown that the average ambient concentrations of suspended particulate matter (SPM) and airborne lead are higher than the Bangladesh national ambient air quality standards and much higher than the WHO guidelines. The city's average SPM levels are about 2 times higher than the Bangladeshi standard of 200 µg/m3 in residential areas and are more than 10 times higher than the WHO guidelines of 120 µg/m3 (24hours) in commercial areas. Lead levels are also high compared to other cities in the world. Although there is a lack of time-series data, the ambient air quality measurements available for 1990 and 1996 onward indicate that the air pollution is worsening.
