Can your lungs get rid of silica?
Your body can get rid of some dust you breathe in. But if you work in a job where you are exposed to high levels of dust for a long time, or work with products containing a high amount of silica, then your lungs become overwhelmed. As a result, your lungs can't get rid of all the dust.
There's no cure for silicosis because the lung damage can't be reversed. Treatment aims to relieve symptoms and improve quality of life. The condition may continue to get worse, leading to further lung damage and serious disability, although this may happen very slowly over many years.
They are irreversible and will continue to get worse the longer you are exposed. The main symptoms of silicosis are: A persistent cough. Shortness of breath.
What is silicosis? Silicosis is a lung disease caused by inhaling very tiny crystalline particles of silicon dioxide, or silica. If you have it, you'll have symptoms of coughing, inflammation (swelling) and fibrosis (scarring).
When people breathe silica dust, they inhale tiny particles of the mineral silica. Over time, the silica dust particles can cause lung inflammation that leads to the formation of lung nodules and scarring in the lungs called pulmonary fibrosis.
Your body can get rid of some dust you breathe in. But if you work in a job where you are exposed to high levels of dust for a long time, or work with products containing a high amount of silica, then your lungs become overwhelmed. As a result, your lungs can't get rid of all the dust.
Symptoms of silicosis usually appear after many years of exposure. In early stages, symptoms are mild and include cough, sputum and progressive shortness of breath. As the scarring continues to worsen, the first real signs of a problem may be an abnormal chest X-ray and a slowly developing cough.
The rarest form of the disease, known as acute silicosis, can involve a single lethal dose or many exposures to a high concentration of silica within two years or less. The silica particles land in the air sacs of the lung, leading to inflammation that causes the sacs to fill up and makes gas exchange impossible.
There is no cure for silicosis and once the damage is done it cannot be reversed. Treatment is focused on slowing down the progression of the disease and relieving symptoms. Avoiding further exposure to silica and other irritants such as cigarette smoke is crucial.
Occupational Standards
In 1974 NIOSH recommended that the exposure limit for respirable crystalline silica be 0.05 mg/m3 averaged over a work shift of up to 10 hours a day, 40 hours a week.
How do lungs get rid of dust?
These tubes are called bronchi and bronchioles. All of these airways are lined by cells. The mucus they produce catches most of the dust particles. Tiny hairs called cilia, covering the walls of the air tubes, move the mucus upward and out into the throat, where it is either coughed up and spat out, or swallowed.
There isn't any treatment that can remove the specks of mineral dust in your lungs. Instead, most treatments try to keep your lungs working. You may need to stop doing the work that led to your pneumoconiosis. If you're a smoker, your doctor will recommend you quit to improve your lung health.
You can get concrete dust out of your lungs by: Opening the airways and helps the lungs expel mucus by breathing water vapour, which is known as steam treatment or steam inhalation.
- Chest X-ray or CT scan: This test checks your lungs for scars.
- Bronchoscopy: The doctor will run a long, thin tube with a tiny camera on the end into your lungs to check for damage.
Not everyone who works with silica dust develops silicosis. The chances of getting silicosis will depend on many factors, including how much silica dust you come into contact with, and for how long you were exposed to it.
The chest radiograph is a relatively insensitive and nonspecific tool for diagnosing pneumoconiosis, because silicosis and CWP are virtually indistinguishable on radiologic studies. In addition, the results may cause underestimation or overestimation of the extent of disease.
Patients with accelerated silicosis may progress to progressive massive fibrosis over a period of four to five years. Overall, people diagnosed with silicosis lose an average 11.6 years of life.
This form of dust is so small that it can stay in the air for up to 12 days. Sometimes when we don't see dust, there are still particles circulating about!
Silicosis cannot be cured or treated, and it's often fatal. Hundreds to thousands of stonemasons are at risk of this deadly disease. Since last year, over 100 have been diagnosed in Queensland alone. In March, one man died from silicosis, aged just 36.
Just as asbestos was found to be dangerous to workers, silica is just as deadly.
What does silicosis look like on an xray?
Plain radiograph
On a chest radiograph, complicated silicosis is usually indicated by large symmetric bilateral opacities that are: 1 cm or more in diameter and with an irregular margin. commonly in the middle lung zone or peripheral one-third of the lung.
Silicosis typically occurs after 15–20 years of occupational exposure to respirable crystalline silica. Symptoms may or may not be obvious; therefore, workers need to have a chest x-ray to determine if there is lung damage. As the disease progresses, the worker may experience shortness of breath upon exercising.
Step 4: Exercise
Cardio exercises are excellent for helping you breathe deeply to oxygenate the muscles of your body, which means that the lungs are 1) getting more air and 2) are getting stronger, both of which can be helpful in combating the inflammation, scar tissue, and expulsion of mucus.
Intense exposure to silica can cause disease within a year. But it usually takes at least 10 to 15 years of exposure before symptoms occur.
Crystalline silica has been classified as a human lung carcinogen, and can cause serious lung disease and lung cancer. It only takes a very small amount of respirable silica dust to create a health hazard.
Lungs are self-cleaning organs that will begin to heal themselves once they are no longer exposed to pollutants. The best way to ensure your lungs are healthy is by avoiding harmful toxins like cigarette smoke and air pollution, as well as getting regular exercise and eating well.
Damaged Lungs Can Repair Themselves, But…
But there is a limit to the lungs' capacity to heal themselves. The chronic injury that is seen after years of smoking, exposure to asbestos, or other lung irritants can cause damage that requires diagnosis and treatment by a pulmonologist.
Many common construction materials contain silica including, for example, asphalt, brick, cement, concrete, drywall, grout, mortar, stone, sand, and tile.
The only way to measure for airborne silica dust is to take samples of the air in necessary workplaces and have them analyzed by a lab.
Abstract. Pulmonary crystal-storing histiocytoma is a very rare disorder and is characterized by infiltration of histiocytes with intracytoplasmic accumulation of crystallized immunoglobulins. It is usually associated with lymphoproliferative diseases or plasma cell dyscrasia.
Can you survive silicosis?
Silicosis IS NOT CURABLE, but it IS PREVENTABLE—to live a long and healthy life, learn the facts and know how to protect yourself and your family.
There is no cure for silicosis and once the damage is done it cannot be reversed. Treatment is focused on slowing down the progression of the disease and relieving symptoms. Avoiding further exposure to silica and other irritants such as cigarette smoke is crucial.
There is no cure. The goal of treatment is to avoid silica dust so the lungs do not get damaged more. To help with breathing the doctor may advise: Avoiding smoking.
There is no specific treatment for silicosis. Removing the source of silica exposure is important to prevent the disease from getting worse. Supportive treatment includes cough medicine, bronchodilators, and oxygen if needed. Antibiotics are prescribed for respiratory infections as needed.

Is silicosis a death sentence?
Silicosis cannot be cured or treated, and it's often fatal. Hundreds to thousands of stonemasons are at risk of this deadly disease. Since last year, over 100 have been diagnosed in Queensland alone. In March, one man died from silicosis, aged just 36.

On a chest radiograph, complicated silicosis is usually indicated by large symmetric bilateral opacities that are: 1 cm or more in diameter and with an irregular margin. commonly in the middle lung zone or peripheral one-third of the lung.
Acute: Symptoms happen a few weeks up to 2 years after exposure to a large amount of silica. Chronic: Problems may not show up until decades after you're exposed to low or moderate amounts of silica. It's the most common type of silicosis. Symptoms may be mild at first and slowly worsen.
There are two types of TB tests: Skin & blood. The blood test does not require a follow-up, so it is more common for a silica physical. If the PLHCP determines that the employee is at higher risk for TB, he/she may request to perform this testing annually.
