The air and noise quality in the Cox’s Bazar area is worse than normal air in the coastal city, according to a latest study.
The study, titled “State of Air Quality and Noise in the Coastal Zone of Bangladesh: A Study in the Cox’s Bazar Area”, also found that Cox’s Bazar is heavily polluted as well as acute noise pollution. compared to the national standard.
Qualifying the main causes of air and noise pollution from construction, industrial and tourism works, the study also indicated that, unless appropriate and adequate measures are taken in our tourism policy to reduce pollution, the sustainability of Cox’s Bazar as a tourist destination would be challenged.
The findings were presented on Sunday at a webinar co-hosted by the Coastal Research Unit (CRU), Department of Geography and Environment, University of Dhaka and the Center for Air Pollution Studies (CAPS), Department of Environmental Sciences, University of Stamford Bangladesh.
Professor Ahmad Kamruzzaman Majumder, Director of CAPS, was the keynote speaker while Professor M Shahidul Islam, CRU Team Leader, chaired the session.
Prof Kamruzzaman mentioned that the air in the coastal town of Cox’s Bazar is highly polluted as well as severe noise pollution by the national standard.
Based on information gathered from 52 locations in the city covering seven types of land use, the study shows that the levels of PM1, PM2.5 and PM10 in Tarabniyar Bazar, Pattaya School Bazaar and Burmese market (mainly of commercial zones) of the city are 4.80 (PM1) and 4.445 (PM10) times higher than the national level and vary from 312.25 µg / m3 to 300.00 µg / m3 for PM2.5, 666, 75 µg / m3 at 618.50 µg / m3 for PM10 and for CO2 from 7 ppm in the residential area to 111 ppm in sensitive areas which is also 1.3 to 2.64 times higher than the national level.
The average concentration of PM1, PM2.5 and PM10 exceeds the standard level in residential areas and road intersections, Professor Kamruzzaman added.
The noise pollution of Bollia para, Tarabaniyar Chora and Madakoccopia National Park (mainly sensitive area and mixed area) ranges from 94.00 dBA to 87.48 dBA, which is also higher than the national value, according to the study.
The question-and-answer session was very dynamic with the active participation of members of CRU and SHIF.
In the closing speech, Professor M Shahidul Islam stressed the importance of monitoring the water quality of the coastal area of Cox’s Bazar. In this case, CRU and CAPS will work together in the future.
