Certainly, it is not "healthy" to breathe any amount of dust containing silica! As these particles damage the lungs, scar tissue forms and limits oxygen absorption. It is also found in concrete, brick, mortar, and other construction materials. 3 The material being worked on may contain other hazardous substances, eg lead. The way that silica dust leads to cancer is both simple and insidious. Silica dust is very fine, much smaller than a tiny grain of sand found on a beach. Silica can be found or manufactured in different forms, broadly divided into crystalline and non-crystalline (amorphous). In severe cases this may result in silicosis, an incurable, sometimes fatal, disease. 8.3.1.2 Fugitive Dust Effect on Human Health. However, high levels of exposure can cause . Lifetime risks of lung cancer were estimated up to age 85 with an actuarial approach that accounted for competing causes of death. Breathing in very small ("respirable") crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. For any kind of dust, there are different particle sizes. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Respirable dust consists of very small particles that can penetrate the deep parts of the lungs. Depending on factors such as how much dust a worker breathes in and for how long, crystalline silica can cause the following health effects: These diseases, caused by dust inhalation, are often described . RCS has a long-term exposure . Habits like smoking can add to lung damage caused by silica. As a result, stricter standards have been set in . It is commonly called silica or silica dust. The most common one associated with occupational overexposure is silicosis. 3 These diseases cause permanent disability and early death. 1272/2008, while crystalline silica dust generated by a work process is not placed on the market and therefore is not classified in accordance with that Regulation. It is the major cause of silicosis, . Silicosis is a occupational lung disease called pneumoconiosis caused by breathing in of crystalline silicon dioxide, tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz.

Crystalline silica is extremely dangerous dust that can cause harm to your health. They include silicosis, chronic obstructive pulmonary disease (COPD) and kidney disease. 3. While there are established health and safety rules concerning exposure, silica dust is still one of the most prevalent causes of respiratory disease, which tells us that there is more that needs to be done. Crystalline silica comes in several forms, with quartz being the most common. It drifts everywhere. Silicosis usually follows exposure to RCS over many years, but extremely high exposures can cause . When inhaled in sufficient amounts, your bodies natural defenses are overwhelmed by these particles and they make their way deep into the lungs causing cellular damage. The quantity of silica contained in stone and other materials varies considerably between different types of stone: Approximate crystalline silica content . What type of cancer does silica cause? The appearance of the scarring caused by crystalline silica is apparently altered by concurrent exposure to amorphous natural diatomite. Initially, individuals may be developing disease even without respiratory symptoms. Silica is a natural resource found in abundance in the earth's crust, stones, natural rock, etc. Crystalline silica is the name for a group of naturally occurring minerals found in many types of rock. Occupational exposure to silica dust has been examined as a possible risk factor with respect to several systemic autoimmune diseases, including scleroderma, rheumatoid arthritis, systemic lupus erythematosus, and some of the small vessel vasculitidies with renal involvement (e.g., Wegener granulomatosis). These dust particles are still very sharp, and when inhaled they damage the lungs. Each exposure to silica adds into the total load of silica in the lungs - in other words, each exposure adds to the lung damage. Materials like sand, stone, concrete, and mortar contain crystalline silica. Imaging tests: A chest X-ray or CT scan can give your doctor a better picture of the lungs so they can assess how much damage has been done and whether or not silica dust is the likely cause.
