Silica, Crystalline

Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis. Silicosis typically occurs after 15–20 years of occupational exposure to respirable crystalline silica. Symptoms may or

The Eye and Immune Privilege

 · The body's immune system—made up of organs, tissues and cells—works to protect us from infection and disease. When a virus or other foreign substance is detected, the immune system kicks in. It makes molecules called antibodies to attack these invading substances known as antigens. This natural defense system is called an inflammatory …

Africa since the 1930s, dust was collected with a konimeter (Le Roux, 1970; Cherrie and Aitken, 1999). A small volume of air (, 5 cm . 3. captured in less than a second) was collected (impacted) onto a small area of a glass slide coated with adhesive. Total dust particles were counted and expressed as dust particles per cubic centimeter. Later, slides were heated to …

What is Silica?

Breathing silica dust can put you at risk for a whole host of respiratory diseases from breathing tiny particles deep into your lungs. It can also set off an immune reaction that damages other tissues or organs. As a result, there is some evidence that silica dust exposure causes kidney failure, rheumatoid arthritis, and other autoimmune conditions. However, its relationship to …

He joked that luckily the infirmary was just round the corner from his yard. Robert also described how there was water everywhere since it was used to keep the …

Occupational Lung Diseases

Exposure to silica can lead to one of three disease patterns: (1) chronic simple silicosis, which usually follows more than 10 years of exposure to respirable dust with less than 30% quartz, (2) subacute/accelerated silicosis, which generally follows shorter, heavier exposures (ie, 2–5 years), and (3) acute silicosis, which is seen often following intense exposure to fine dust of high silica


pulmonary disease (including chronic bronchitis and emphysema), silicosis, lung cancer, and renal disease. Lung defence mechanisms against the very fine dust that penetrates to the alveolar oxygen exchange part of the lung can be overwhelmed by silica particles, which can be toxic to macrophages. Silicosis can result from exposure to RCS over
