Analysis of asbestos

Analysis of asbestos is critically important because of the need to distinguish the elements around us are dangerous for human beings exposed to. The asbestos is known to be very dangerous, analysis of the substance continues to the present day.

The word "asbestos" is the term used for natural fibrous minerals. Its various types of substance. This list of different types include chrysotile, crocidolite, amosite (cummingtonite-grunerite asbestos), asbestos tremolite asbestos actinolite, anthophyllite asbestos, and either of these minerals than chemically treated or altered.

The precise chemical formulation of each species varies depending on the location from which was mined. Nominal compositions of asbestos are shown here:

Chrysotile... Mg (3) if (2) or (5) (O) (4)
Crocidolite... NA (2) faith (3) (2) (+) faith (2) (3) (+) if (8) or (22) (OH) (2)
Amosite... (Mg, Fe)(7)If (8) or (22) (OH) (2)
Tremolite-actinolite... CA (2)(mg,fe) (5) if (8) or (22) (OH) (2)
Anthophyllite... (Mg, Fe)(7)If (8) or (22) (OH) (2)

To compare the level of danger of these toxic and hazardous materials, is that it is dangerous chrysotile (white asbestos), amosite (brown asbestos) is 100 times moredangerous and crocidolite (blue asbestos) is 500 times more dangerous.

Early studies of analysis to determine the risks of asbestos were performed using counts impinger total dust with the counts expressed in millions of particles per cubic foot.

The BARC recommends membrane filter in late 1960s. OSHA Office published a procedure for the membrane filter to the numbering of the fibers of asbestos in the United States in 1969.

This partcular procedure was perfected by the National Institute for health and safety and published as P & CAM 239. May 29, 1971, specified OSHA sampling membrane filter with phase-contrast counting for the assessment of the risks of asbestos in the workplace in North America. The use of this technique was once again required by OSHA in 1986. Phase-contrast microscopy has continued to be the method of choice for the measurement of occupational exposure to asbestos.

Asbestos analysis studies are key in the fields of science and medicine. The more information that the society may be obtained from these studies, better. There is no threshold known by the number of asbestos fibers can cause mesothelioma. However ofdeveloping cancer odds are dramatically increased for large risks and low levelexposures consistent with the time.
