“…During the pre-monsoon season (March-May) there is high RH, high temperatures, moderate rainfall, and prevailing SW winds; the monsoon (June-September) brings high rainfall with high speed SW winds; post-monsoon season (October-November) typically has low rainfall, RH, and NE winds, and in winter (December-February), the Ommi et al, Aerosol and Air Quality Research, 17: 465-475, 2017 467 conditions are very dry with low NW winds (Begum et al, 2013). Begum et al (2014) used positive matrix factorization (PMF) to analyze the PM 2.5 compositional data from Rajshahi, Dhaka, Khulna and Chittagong. Concentrations of Na, Mg, Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Br, Pb, BC and Delta-C were used.…”

“…Multiple source apportionment studies using positive matrix factorization (PMF) have also been conducted (e.g., Begum et al, 2004Begum et al, , 2005Begum et al, , 2009Begum et al, , 2010. These results suggested that the typical haze aerosol comes from domestic wood, dung and bagasse burning, forest fires, and combustion connected to agriculture activities and brick kiln making, i.e., biomass burning in general, but also from traffic, power plants, industry emissions, soil and road dust, and also sea salt (Begum et al, 2014). Ramanathan and Carmichael (2008) report that biomass burning is the major source of black carbon and particulate matter across southern and southeastern Asia.…”

“…Recently, source apportionments were performed for four cities in Bangladesh; Dhaka, Rajshahi, Khulna, and Chittagong (Begum et al, 2014) to determine changes in the PM sources resulting from governmental interventions and compare source strengths across the country. The results showed that the AAQS was not attained in any of the cities and thus, further regulation would be necessary.…”

“…The main difference was in the impacts of wood burning and brick kiln factors, both connected to biomass burning. That study concluded that long-range transport of biomass burning aerosol from northern India was the possible explanation for the higher values and suggested that a "further study of the role of this transported aerosol will be needed to assess the source locations and contributions in more detail" (Begum et al, 2014).…”

Biomass burning is a major global source of fine primary carbonaceous particles including strongly light absorbing compounds and marker compounds. In a prior study, particulate matter (PM) sampling was conducted during 2010-2012 period at sites in Rajshahi, Dhaka, Khulna, and Chittagong. PM samples were collected using dichotomous samplers in the PM 2.5 and PM 2.5-10 size fractions. The samples were analyzed for mass, black carbon at 370 nm (UVBC) and 880 nm (BC), Delta-C (UVBC-BC), and elemental compositions with X-ray fluorescence. Source apportionment using PMF was performed to identify and quantify the PM sources. Results showed that biomass burning contributions during winters in Rajshahi were substantially higher than in Dhaka, Khulna, or Chittagong. Agricultural burning areas of the Indo-Gangetic Plain were hypnotized as the primary source region. The present study explores the relationships between the source regions using trajectory ensemble models and determines if transported biomass PM has disproportionately affected air quality in Rajshahi. The probable source locations that were identified included Pakistan, northern India, Nepal, Bangladesh, Northeastern India, and Myanmar. To assess the model results, satellite measurements of fire radiative power (FRP) were calculated based on fire data acquired by the MODerate-resolution Imaging Spectro-radiometer (MODIS) sensor in six defined areas. High fire occurrences from MODIS coincident with the source regions identified in Nepal, Northeastern India and Myanmar in winter. The instantaneous FRP values ranged between 4.4 MW and 2449 MW. The mean winter FRP values for Nepal and Northeastern India were higher than for the other regions with Nepal having the overall highest value. Fire locations with their mean power, NASA Satellite pictures and particles speed along trajectories have been analyzed. In summary, the integrated outcome of the different techniques has identified Northern India and Nepal as the main source area responsible for the increased biomass burning concentration difference at Rajshahi.

Air quality degradation due to high levels of atmospheric particulate matter (PM) of various size fractions and the associated potentially toxic trace elements (PTEs) is a global concern. This article provides a thorough review and analysis of the temporal and spatial distribution of PM and PTEs in Bangladesh, offering a comprehensive assessment with other megacities worldwide based on existing literature. This study provides insights into the sources and transport mechanisms of PM and their link to human health. The level of PM was consistently high in Dhaka (capital of Bangladesh), with occasional higher levels in the surrounding cities. Different functional areas within Bangladesh show varying levels of PM, with total suspended particulates (TSP) being notably prevalent. When compared to megacities worldwide, African and Asian megacities, like India, Pakistan, Nigeria, and Egypt, exhibited higher PM concentrations. The concentration of PM-associated PTEs varies significantly among megacities and PM10 tends to have relatively higher concentrations of PTEs compared to other fractions in Bangladesh. Pb in ambient air was found across most megacities, with a temporal increase in Bangladesh. TSP exhibited the highest relative Pb content, followed by PM10 and PM2.5. Temporal factors, geographic locations, meteorological conditions, and anthropogenic activities contribute to the variation in PM and associated PTEs concentration in Bangladesh and global megacities. Ultimately, this study would aid policymakers in assessing the magnitude of PM pollution in Bangladesh compared to other megacities considering regional factors.
