Meanwhile, Dhaka, the capital of Bangladesh, was at the top among the world's cities in terms of air pollution around 11 am on Friday. At 10:06 pm, the position of Dhaka was the same. However, there is some change in this position throughout the day. The information about Dhaka's air pollution has been obtained from IQ Air, a Swiss-based website that monitors global air quality.
As a tropical country, Bangladesh has a lot of dust. For the next few years, dust pollution increased uncontrollably in the open environment. These include large projects such as the Metrorail, some areas such as Purbachal City and Bochilla, and numerous small housing projects. Added some ditches like Mohammadpur embankment. Apart from these places, dust is also seen in Gabtali, Jatrabari, Purbachal, Keraniganj, Tongi and some other areas at the entrance of the capital.
Even in this situation, the implementation of the guidelines for prevention of air pollution of the Ministry of Environment was not seen last year. The guidelines cover construction materials during road construction, use advanced technology such as mini asphalt plants without sprinkling sand on bitumen, cover roadside soil with concrete or grass, use vacuum sweeping trucks instead of road sweepers, spray water at least twice on major roads. The initiative was not noticed.
The big responsibility is unplanned urbanization
According to the Bangladesh Institute of Planners (BIP), an ideal city would have building and road infrastructure (60 percent), green (25 percent) and water (15 percent). Besides, new cities have to be built without expanding the city. Between the two parts there will be buffer area (regional forest, agricultural land and floodplain area).
BIP general secretary Adil Muhammad Khan told Prothom Alo that Dhaka has three to four times the capacity of the city. Even after that industrialization, concrete buildings, housing projects are being done. Buffer areas are being filled with soil and sand and construction work is going on. As a result, pollution prevention areas are increasing pollution. It is not possible to soak the dust for a long time in warm weather just by sprinkling water.
