Brick kilning, air pollution, environmental pollution, Khulna


This study identifies the patterns of energy consumption in brickfields as well as their impacts on the environment. An attempt has been made to estimate the emission of pollutants from brickfields to assess the impacts of the pollutants on human health. Finally, an attempt has been made to find out a solution to sink the CO2 emitted by brickfields. Brickfields use coal, wood fuel, and crude oil mainly for burning bricks. Estimation reveals that in Khulna Region (KR) for the years 2003-2004, the coal requirement was 162 kton while the wood fuel required was 133 kton. Estimation also reveals that for KR the annual emission of the pollutants are about 738608 tons CO2, 94 tons of CH4, 13 tons of Nitrous Oxide (N2O), 1989 tons of NOx, 4264 tons of CO, 168 tons of Non-Methane Volatile Organic Carbon (NMVOC) and 15942 tons of SO2. Estimation also shows that, for the present level of CO2 emission in Bangladesh, annual afforestation requirement is about 1.4 x 109 m2. The predicted concentration at 200 m downwind of brickfields is 3000 μg/m3 for SO2 and 300 μg/m3 for NOx and PM-10 during winter, while for summer the concentration is 1000 μg/m3 and 125 μg/m3 respectively. From the high concentration of these pollutants people face some health problems. About 30% of the brickfield workers suffer from dizziness while 60% feel fatigue and 75% suffer from headache. Those working for many years feel fatigue more than the new comers, 55% and 3% respectively.
