|Description:||Under a high magnification of 1000X, this scanning electron microscopic (SEM) image revealed some of the microcrystalline ultrastructure exhibited by a piece of raw chrysotile, or white asbestos, which had been excavated from the Lowell Asbestos Mine on Belvidere Mountain, Vermont.|
Note the elongated crystalline structure, and how the fibrils are arranged in both bundles, and as singular serpentine units. See PHIL 11034 through PHIL 11066, for additional photomicrographic views of this material.
When a substance is released from a large area, such as an industrial plant, or from a container, such as a drum or bottle, it enters the environment. This release does not always lead to exposure. You are exposed to a substance only when you come in contact with it. You may be exposed by breathing, eating, or drinking the substance, or by skin contact.
If you are exposed to asbestos, many factors determine whether you’ll be harmed. These factors include the dose (how much), the duration (how long), the fiber type (mineral form and size distribution), and how you come in contact with it. You must also consider the other chemicals you’re exposed to and your age, sex, diet, family traits, lifestyle (including whether you smoke tobacco), and state of health.
