Note that it can not distinguish between the three types the naked eye as a result because the colors are affected by age, temperature and mixing with other materials 0
Third: - uses of asbestos
The properties and features that characterized the asbestos has been combined with other materials in many industries including: -
Insulators: - isolated in the pipes and bricks and cement asbestos insulation
Textiles: - in the manufacture of gloves, blankets and protective clothing

- Cause asbestos disease if been inhaled Oaptlall where person inhales without feeling that the small size of asbestos fibers
- And I've had exposure to asbestos fibers occurs only in factories and thus get people working on them but now after what has become of asbestos used in construction materials became exposure to these fibers in schools, homes and public buildings such as hospitals, when refractive this article Vtaattaar asbestos fibers in the air of the spread in the atmosphere, which affects the human health, especially children
- And have found that the incidence of diseases caused by asbestos depends on several factors such as: -
The concentration of asbestos fibers in the air.
Shape and size of these fibers.
Response to the same person.
Duration of exposure.
Flexible and is in custody in corrugated upper respiratory passages (nose and pharynx, larynx and trachea) and is expelled through the mucous cilia and if you arrive not cause lung tumor 0
The fiber straight land they lined up in the direction of the air to reach deep into the lungs and cause malignant tumor 0
- But is worth mentioning that all the asbestos fibers in general cause fibrosis of the lung so it's creating tumors and Catalyst 0
- In addition to the asbestos fibers merge with Alkmoyat toxic carcinogens such as those found in cigarettes leads to increased incidence of malignant tumors, studies have shown that citizens exposed to fibers Aalocepctos more susceptible to lung cancer incidence for others 0
