Brick Making in Bangladesh

The contribution of Brick Kilns to ground level particulate air pollution in the Dhaka district of Bangladesh was investigated in a paper by Abdullah Al Nayeem, Md. Sahadat Hossain, Ahmad Kamruzzaman Majumder, and William S. Carter in the International Journal of Environmental Pollution & Environmental Modelling. The paper, Spatiotemporal Variation of Brick Kilns and it’s relation to Ground-level PM2.5 through MODIS Image at Dhaka District, Bangladesh (2019) is available at this link.

PM2.5 concentrations were three to four times higher than the Bangladesh National Ambient Air Quality Standard (BNAAQS) and World Health Organization (WHO) standards, with an increasing trend between PM2.5 concentration and number of brick kilns. Hence, standardizing kiln efficiency through improved combustion techniques along with promotion of sand bricks could reduce emission from brick kilns in Bangladesh.
