Size and shape of airborne asbestos fibres in mines and mills.

There is increasing evidence that fibre size and shape play an important part in the production of health effects related to asbestos. The dimensions of airborne fibres collected at various stages of fibre processing in three mines and six mills producing three types of asbestos were measured using phase contrast light microscopy and transmission electron microscopy.

No airborne fibres had a diameter greater than 3 micrometers, and all would therefore be capable of reaching the pulmonary alveoli. It was shown that for the same airborne mss of the different varieties of asbestos, fewer amosite fibres would be present than crocidolite or chrysotile fibres. Most of the fibres to which workers are exposed are ...

Asbestos: What Is Asbestos and How Does It Cause Cancer

Asbestos is an effective insulator, and it can be used in cloth, paper, cement, plastic and other materials to make them stronger. But when asbestos dust is inhaled or ingested, mineral fibers can become permanently trapped in the body. Over decades, trapped asbestos fibers can cause inflammation, scarring and eventually genetic damage.
