A problem: This varies widely on its severity based on the fineness of the dirt. If it is quite fine it gets into and damages the lungs permanently and is quite dangerous. Mostly any filter mask will work quite well on this. A chest x ray will demonstrate damage if it is there and simple office tests such as oxygenation and listening to the lungs will be able to show significant damage.
