Air Pollution From Brick Kilns

explained: how brick kilns contribute to rising pollution,how much pollution does a kiln create in a single operation? according to the science and technology department, if a kiln runs on the old technology, its emission levels are 500 to 1500 mg/nm3 (carbon, sulphur and several other harmful metals in the air). meanwhile, an upgraded brick kiln’s emission levels were found to be in the range of 105 to 195 mg/nm3, and it can check particulate.(pdf) brick kilns: cause of atmospheric pollution,the brick kiln exhaust not only contributes significantly to air pollution but also cause a reduction of crop yield (sharma, 2000), poor vegetation growth as well as soil degradation and reduction....
