Asbestos minerals consist of thin, separable fibers that have a parallel arrangement. Tremolite belongs to the amphibole family of minerals and has needlelike fibres. Tremolite asbestos can be found in a variety of construction materials and insulation materials. Abestos is toxic and inhalation of asbestos fibers can cause serious illnesses, including malignant mesothelioma, lung cancer, and asbestosis. While all forms of asbestos are hazardous and can cause cancer, amphibole forms of asbestos are considered to be somewhat more hazardous that their serpentine counterpart (chrysotile). (L221, L222)"}]
