effects of breathing cement and stone dust

Farmers will develop specific symptoms of farmer's lung based on the amount of dust and spores to which they have been exposed or the intensity of their body's reaction to the dust and spores. Farmers are also likely to develop an increased sensitivity to mold exposure over time and will have more severe reactions with lighter exposures. Characteristics of the person inhaling particles can also influence the effects of dust. Breathing rates and smoking are among the most important. The settling of dust in the lungs increases with the length of time the breath is held and how deeply the breath is taken.
