Asbestos by TEM
Sampling & Analysis
Asbestos is a white, greenish, blue, or gray-green fibrous, odorless solid. It has been in use for over 6000 years in weaving, when its fire-retardant properties were first discovered. At the end of the 19th century, it was used in a number of products such as insulation on electric wiring, road surfaces, flooring, home heat duct insulation, automobile brake linings, cement, and heat-resistant packaging materials. When mined or broken down, the fibers can enter the body through inhalation and over prolonged exposure can cause lung cancer. Short-term exposure can cause difficult or restricted breathing. Asbestos can also irritate the eyes and skin.
