How are brick kilns harmful to the environment?

Emission of huge quantity of toxic elements from brick kilns is causing serious health hazards. The brick kilns emit toxic fumes containing suspended particulate matters rich in carbon particles and high concentration of carbon monoxides and oxides of sulphur (SOx) that are harmful to eye, lungs and throat.

Are there any health issues with brick making?

Another concern with brick making are the fluorine emissions associated with the process. Some brickworks have installed scrubbers to lessen the emissions of this substance, which can be dangerous to human health. However, these are expensive and so not all businesses can afford to comply.

What happens if bricks are left untreated?
