WHITE (CHRYSOTILE) ASBESTOS: This is the most common type of asbestos used in industrial processes in the United States. White asbestos is thought to be not as dangerous as other types of the mineral. The main source of this material comes from Quebec, Canada, although there are substantial deposits throughout North America and Europe.
BROWN (AMOSITE) ASBESTOS: Brown asbestos is relatively uncommon, and comes from the extensive mines of South Africa. It is believed to cause pleural and peritoneal mesothelioma, as well as lung cancer.
BLUE (RIEBECKITE) ASBESTOS: Blue asbestos comes from Africa and Australia, and is most often believed to be the most dangerous form of asbestos. It is well known to cause serious medical conditions such as mesothelioma and lung cancer.
