Urban Air Pollution Caused of Particulate Matter and Lead in the City of Chittagong-Bangladesh

Abstract

Chittagong city is one of the largest and commercial cities of Bangladesh. Many industries are continuously producing particulate matters by their daily activity. Air pollution due to the PM has significant effects on asthma, allergy and other respiratory diseases. There is a great need to implement control measures in most of the megacities of the world to improve air quality and hence protect public health. Like many megacities in the world the ambient air quality of Chittagong is also being deteriorated day by day. Main sources of air pollution are particulate matter in this city are arising out emitted directly from a source, such as construction sites, unpaved roads, fields and fires. Most particles form in the atmosphere as a result of complex reactions of chemicals from sulfur dioxide and nitrogen oxides, which are pollutants emitted from power plants, industries and automobiles. Considering that, the current study plan was undertaken to measure the pollutants level in the air of different urban locations of Chittagong, the second largest city of Bangladesh. Atmospheric pollutants such particulate matters (PM2.5, PM10 and PM) and lead (Pb) were determined in Chittagong city. Eight different sampling stations,

Effect of air pollution on plant life in the city of Chittagong, Bangladesh

“…In 2021, the studied data showed that the average concentration of particulate matter (PM2.5) was 80.15, 83.14, 83.06, 67.03, 68.74, 69.20 and 69.17 µg/m 3 for the WASA Circle, the GEC Circle, Proborthak Circle, Chawkbazar Circle, Alongkar Circle, New Market Circle, Oxygen Circle, respectively, in the city of Chittagong. The previously established data was too high than in the current study [26].…”

“…The PM2.5 and PM10 particles were collected using a combined dust sampler (Lata Envirotech APM 250) for 24 hours for each location and analyzed according to Equations 5 and 6 [26].…”
