Inhalation of asbestos fibers can cause serious diseases

Asbestos is a mineral silicate of natural origin with a long thin fibrous crystals. The word asbestos  borrowed a Greek adjective meaning lime. The Greeks termed asbestos the miracle mineral soft and flexible properties and its ability to withstand heat.

Asbestos can be toxic. Inhalation of asbestos fibers can cause serious diseases, including malignant lung cancer, mesothelioma (a malignant tumor type dependent (), mainly asbestos) [edit] a kind of pneumoconiosis, and asbestosis. Since mid 1980, the European Union and most developed countries have banned asbestos. [Edit].

For environmental samples are generally used electron microscopy for positive identification. [1] Today, however, gravity and PCM / PLM techniques that can easily locate the smallest, most dangerous fibers. These techniques are limited to assessing the size of PM10, which completely ignores UFPs.

Asbestos became increasingly popular among manufacturers and manufacturers in the late 19 Because of the resistance to heat, electricity and chemical damage, sound absorption and tensile strength century. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. Asbestos was used in some products on the heat resistance and in the past for the oven and the wiring plate for electrical insulation at elevated temperature, the buildings on the properties of flame retardant insulation, strength, flexibility and chemical resistance. http://www.tcmwell.com
