Scientists Have Found The Effect Of Silica On The Lungs

Scientists Have Found The Effect Of Silica On The Lungs.
More effectiveness is needed to reset illness and death among the millions of Americans exposed to silica dust at work, according to a redesigned report Dec, 2013. It has hunger been known that silica - a natural substance found in most rocks, sand and clay - causes the lung complaint silicosis, and evidence has mounted in recent decades that silica causes lung cancer, said announcement co-author Kyle Steenland, of the School of Public Health at Emory University hoodia gordonii patch. "Current regulations have in truth reduced silicosis death rates in the United States, but untrained cases of silicosis continue to be diagnosed".

Recommended measures include stronger regulations, increased awareness and prevention, and greater acclaim to early detection of silicosis and lung cancer using low-dose CT scanning, the researchers said in the common issue of CA: A Cancer Journal for Clinicians chudai. "While the lung cancer gamble associated with silica exposure is not as large as some other lung carcinogens, be partial to smoking or asbestos exposure, there is strong and consistent evidence that silica direction increases lung cancer risk," Steenland said in a journal news release.

The imperil of on-the-job exposure to silica is highest in the construction industry. Exposure occurs when workers cut, grind, squeeze or drill silica-containing materials such as concrete, masonry, tile and rock. About 320000 US workers are exposed to silica dust in operations such as foundry work, sandblasting and brick, particular and ceramics manufacturing.

Silica exposure also occurs from hydraulic fracturing (fracking) in grease and gas wells. The most effective ways to control silica exposure on the job embody banning sandblasting, avoiding abrasive blasting, modifying processes and equipment, controlling dust transmission, and using dear protective equipment, the report said nootropic. Although people are exposed to inferior levels of silica on beaches and in the air, there is no evidence that such low-level exposure affects health, the divulge said.
