There are 101 brick kilns in the district.
"As some brick kilns are situated close to residential areas, they cause severe air pollution. Pollutants such as carbon monoxide, sulphur dioxide, nitrogen oxides and suspended particulate matter are released in the atmosphere by brick kilns. I am glad that the authorities finally woke up to the issue," said Aseem Takyar, who has been filing RTIs regarding the issue.
