The three main kinds of asbestos that have been used commercially are Amosite, Crocidolite, and Anthophilite.
Chrysotile - White Asbestos = Mg3(Si2O5)(OH)4 Amosite (Grunerite) - Brown asbestos = Fe7Si8O22(OH)2. Crocidolite - Blue asbestos = Na2(Fe,Mg)5Si8O22(OH)2. These are the 3 common types
Asbestos exposure has been linked with many diseases. The most common are mesothelioma, lung cancer. gastrointestinal cancer, and asbestosis.
Asbestosis is most common in men over 40 who have worked in asbestos-related occupations
If you work with asbestos you may get little wartlike bumps on your skin. This is caused by an asbestos fiber irritating the skin. It is not common form of dermatitis.
The most common problem occurs when householders want to demolish an oldgarage with asbestos roofing.
Asbestos disease typically affects the human lungs and causes damage in a variety of ways. The most common symptoms are shortness of breath, crackling sounds in the lungs, dry cough, and a feeling of fatigue.
Most areas will have by-laws about covering asbestos.
Asbestos is very toxic and can lead to cancer. The most severe of these cancers is Mesothelioma. A person can get cancer up to 25 years after exposure to asbestos.
Approximately 80% of all mesothelioma patients have a history of asbestos exposure. The majority of these patients were employed in an industry that involved the use of asbestos in some fashion.
While the term " asbestos cancer " most often refers to mesothelioma, a number of other cancers are associated with asbestos exposure. Lung cancer, for example, is a direct result of asbestos exposure, and some studies have suggested an association between asbestos exposure and gastrointestinal and colorectal cancer. Mesothelioma cancer is the only asbestos-related cancer almost exclusively caused by asbestos. Mesothelioma can develop after someone inhales or ingests elevated amounts of asbestos over time. Lung cancer is the second most common cancer in the United States and the Occupational Safety and Health Administration calls it "the greatest health risk for American asbestos workers." Asbestos-related lung cancers are diagnosed more frequently than any other type of asbestos-connected disease. The Environmental Working Group estimates that between 5,000 and 10,000 asbestos-related lung cancer fatalities have occurred each year over the span of the last two decades.
Asbestos is not used in today's modern technologies. Currently, most of the Western and Developed world have banned all uses of Asbestos.
One type of asbestos (chrysotile) can cause a type of lung cancer (mesothelioma) and most types of asbestos cause a lung disease called asbestosis (a type of silicosis), when small airborne fibers of the asbestos are inhaled.
