Prevalence and risk factors for silicosis among a large cohort of stone
The objectives were to (1) determine the prevalence of silicosis in a large cohort of high-risk SBI workers; (2) determine factors associated with increased risk of silicosis and (3) Background: Underground mining generates large amounts of dust and exposes workers to silica. This study aims to determine the prevalence and predictor factors for the Silicosis prevalence and risk factors in semi-precious stone mining

(PDF) Exposure profile of respirable crystalline silica in stone
Silica is a major pollutant which releases into the workplace air of many industries, and it causes silicosis and pulmonary diseases. Control of silica in high-risk factories such as silicaSilica dust is a major environmental and health issue in many quarries 14 especially in developing countries including Ghana. A study by Scarselli et al, 15 revealed that exposure to crystalline silica is most common in quarries, construction, and the mining industry. Quarry operations that are sources of dust include drilling, cuttingSelf‐reported disease symptoms of stone quarry workers

Challenges and Future Prospective of Alternative Materials to Silica
The silica sand used for foundry industries contains silica (SiO 2), Al 2 O 3, and Fe 2 O 3. The consumption of silica sand in India has been increased by 78.98% from 2010–2011 to 2015–2016, and the price of silica sand rises by 72.8% in five years. As the demand for silica sand increases, river sand mining and cost also increase.SLATE STONE . GRAVEL : SPOTASH BRINE . GYPSUM : OCHER .

Natural stone waste generation from the perspective of natural stone
The industrial processing of dimensional stones generates a significant amount of waste. According to the data released in 2020 by the nations with active dimensional stone industries, it is estimated that out of 316 million tons of dimensional stones extracted each year, 161.5 million tons end up as mining or quarry waste.Engineered stones are novel construction materials associated with a recent upsurge in silicosis cases among workers in the stonemason industry.

Concentration, sources and health effects of silica in ambient
The highest percent of samples containing silica is in OC mining followed by long wall and board and pillar methods. Abundance of OC operations for coal mining are the major source of ambient dust generation in JCF. Most of the sources of silica in JCF region are brick kilns, smokestacks, stone chip industry, drilling, crushing, geogenicINTRODUCTION. Silicosis is not a new disease; the impact of silica dust on respiratory function was observed by Hippocrates in 430 B.C. 1 and in the 16th century by Agricol. In 1713, Rammazini described silicotic nodules in post-mortems of stone cutters presenting with respiratory symptoms. 2 In the mid-late 1800s, the introduction of Silica‐associated lung disease: An old‐world exposure in modern industries
