Silicosis. Silicosis is a long-term lung disease caused by inhaling large amounts of crystalline silica dust, usually over many years. Silica is a substance naturally found in certain types of stone, rock, sand and clay. Working with these materials can create a very fine dust that can be easily inhaled.

Respirable crystalline silica dust generated during stone crushing operations has been linked to chronic lung disease and increased risk of tuberculosis. In India, most stone crushing mills operate without any dust control or containment systems.

Stone crushing is a global phenomenon, and has been the cause of concern everywhere in the world, including the advanced countries. Dust from quarry sites is a major source of air pollution, although the severity will depend on factors like the local microclimate conditions, the concentration of dust particles in the ambient air, the size of ...

Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc., Non-occupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as non-industrial sources.

It also shows that coughing was the most common problem among the respondents. The majority of respondents suffered from obstructive types of respiratory problems.,Findings of the study reveals that chronic exposure to dust at stone crushing plants increases the risk of respiratory problems and the impaired lung function of workers.

The stone crushing sector, though socio-economically important, create a substantial amount of environmental pollution by way of both process sources and fugitive sources.

Silicosis is a primary pneumoconiosis involving fibronodular lung disease caused by inhalation of silica dust. Quartz, the most common form of crystalline silica, is abundantly present in granite, slate, and sandstone. [] Although silicosis has been recognized for many centuries, its prevalence increased markedly with the introduction of mechanized mining.

But the stone quarries and crushers being highly polluting, various safety and precautionary measures towards dust suppression, dust exposure and related accidents should be taken. All these units irrespective of their size should follow the rules and regulations prescribed by the state and Central Government, Pollution Control Boards.
