Stannosis
Stannosis is an occupational, non-fibrotic pneumoconiosis caused by chronic exposure and inhalation of tin. Pneumoconiosis is essentially when inorganic dust is found on the lung tissue; in this case, caused by tin oxide minerals. Dust particles and fumes from tin industries, stannous oxide (SnO) and stannic oxide (SnO2), are specific to stannosis diagnoses. Hazardous occupations such as, tinning, tin-working, and smelting are where most cases of stannosis are documented. When melted tin ions are inhaled as a fume, the tin oxides deposit onto the lung nodules and immune response cells. If a worker is exposed to tin oxides over multiple events for an extended time, they are at risk of developing stannosis. Toxicology and physiology Workers with acute exposures, short duration with varying dose concentrations, to tin oxides develop a mild irritation on the eyes, skin, and mucous membranes. When the inorganic metal materials are inhaled, the body activates the immune system and sen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumoconiosis
Pneumoconiosis is the general term for a class of interstitial lung disease where inhalation of dust ( for example, ash dust, lead particles, pollen grains etc) has caused interstitial fibrosis. The three most common types are asbestosis, silicosis, and coal miner's lung. Pneumoconiosis often causes restrictive impairment, although diagnosable pneumoconiosis can occur without measurable impairment of lung function. Depending on extent and severity, it may cause death within months or years, or it may never produce symptoms. It is usually an occupational lung disease, typically from years of dust exposure during work in mining; textile milling; shipbuilding, ship repairing, and/or shipbreaking; sandblasting; industrial tasks; rock drilling (subways or building pilings); or agriculture. It is one of the most common occupational diseases in the world. Types Depending upon the type of dust, the disease is given different names: * Coalworker's pneumoconiosis (also known as coal miner' ...
