Crocidolite asbestos
One of the six types of asbestos. Crocidolite or "blue asbestos," is found in specialized high temperature applications.

Parenchymal fibrosis
It is easily conceivable that prolonged retention of some types of minerals in the lung would be a stimulating factor for inflammatory and neoplastic processes, leading in turn to parenchymal fibrosis and peripheral cancer.

Anthophyllite
A type of asbestos in the amphibole group; it is also known as azbolen asbestos.

Acute Exposure
Exposure to a chemical for a duration of 14 days or less, as specified in the Toxicological Profiles.

Chrysotile Asbestos
A fibrous member of the serpentine group of minerals. Chrysotile asbestos fibers are flexible and have a curved morphology. It is the most common form of asbestos used commercially, also referred to as white asbestos.

Cancer Effect Level (CEL)
The lowest dose of chemical in a study, or group of studies, that produces significant increases in the incidence of cancer (or tumors) between the exposed population and its appropriate control.

Asbestos Containing Material (ACM).
Any material or product that contains more than one percent asbestos.

Asbestos
A general term applied to certain polysilicate fibrous minerals displaying similar physical characteristics although differing in composition. The most common asbestos mineral (over 95% of U.S. production) is chrysotile, a variety of serpentine, a metamorphic mineral.

Bronchial Lung Cancer
Malignant tumor of the bronchial tubes, this disease is more common than Asbestosis & Fibrosis.

Alimta (pemetrexed for injection)
Alimta is a new cancer drug used to treat malignant pleural mesothelioma. Alimta is given with cisplatin, another anti-cancer medicine.
