Quarry companies risk losing their licence if they fail to adopt new air-quality guidelines. The Government rules follow complaints from residents about the quarrying industry, their subsequent health problems and the environmental impact. Respirable dust is dangerous as it settles in the lings, forcing the heart and lungs to work harder to provide oxygen to the body. It can also lead to heart damage. Is enough being done to stop quarries from creating toxic dust clouds? Do you think the new rules will be easy to enforce? Will it make a difference to the environment?
