Silica dust is harmful when inhaled into your lungs. As it is 100 times smaller than a grain of sand, you can be breathing it in without knowing. Exposure to silica dust can lead to the development of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease and chronic obstructive pulmonary disease.

Sample collection and analysis. Bakhrija quarry is surrounded by a number of stone crushing units (≈ 25 units) around it. Samples of suspended particulate matter (PM 2.5 and PM 10) were collected from four locations in and around Bakhrija mines during the pre-monsoon season (June 2019).During the sample collection, the ambient …
The concentration of silica in occupational conditions is well defined and estimated around the world. Many countries in the world have developed air standards for occupational conditions based on the percent silica in ambient air. This is due to the pulmonary effect caused by silica yielding diseases like silicosis and pneumoconiosis. …
