Silicosis that develops 5–10 years after first exposure to higher concentrations of silica dust. Symptoms and x-ray findings are similar to chronic simple silicosis, but occur earlier and tend to progress more rapidly. Patients with accelerated silicosis are at greater risk for complicated disease, including progressive massive fibrosis (PMF).
Respirable crystalline silica – microscopic particles of silica can be become airborne and inhaled when cutting, sawing, grinding, or drilling rock or concrete. Silica is used for foundry molds and cores, so exposure can occur when grinding on castings. Fracking uses silica. About 2.3 million individuals in the U.S. are exposed to silica at work.
A study published two months after 9/11 found that Americans across the country experienced substantial symptoms of stress after the attacks. [25] Two subsequent studies found that exposure to the attacks was a predictor of the development of PTSD.
The new study estimated that 100,000 workers in the U.S. are potentially at risk of silicosis due to exposure to silica dust. Dr. Jane Fazio, a co-author of the study and a pulmonary specialist at ...
A Los Angeles County case poses a test of whether companies that make engineered stone can be successfully sued amid the devastating rise of silicosis, which has killed more than a dozen ...
The grinding and sanding of synthetic engineered stone exposes workers to high levels of lung-scarring silica. Experts say the health risk should have been clear long before workers began falling ill.
Although it has been defined as an extension of pneumoconiosis, there is no scientific evidence for a similar disease related to volcanic silica particle exposures. [8] Subsequently, the word was used in Frank Scully's puzzle book Bedside Manna, after which time, members of the N.P.L. campaigned to include the word in major dictionaries. [9] [10]
Exposure to silica can cause Silicosis, which is a fibrosing interstitial lung disease caused by inhaling fine particles of silica, most commonly in the form of quartz or cristobalite. Short-term exposures of large amounts of silica or long-term (10 years or more) exposure of lower levels of silica can cause silicosis.
