Suspect material
Building material suspected of containing asbestos, e.g., surfacing material, floor tile, ceiling tile, thermal system insulation, and miscellaneous other materials.

Lethal Concentration(50) (LC50)
A calculated concentration of a chemical in air to which exposure for a specific length of time is expected to cause death in 50% of a defined experimental animal population.

Intermediate Exposure
Exposure to a chemical for a duration of 15-364 days, as specified in the Toxicological Profiles.

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.

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.

Stage 3 Mesothelioma
Stage 3 mesothelioma has spread to the chest wall, food pipe (oesophagus) or lymph nodes on the same side of the chest

Pericardial mesothelioma
Pericardial mesothelioma is a highly lethal and fortunately rare cardiac neoplasm

Asbestosis
A chronic lung disease, resulting from the scarring of the lung tissues by asbestos fibers.

Asbestiform
Possessing the properties of asbestos. Minerals of specific chemical compositions can have asbestiform varieties that are fibrous in nature (e.g., crocidolite and amosite are the asbestiform varieties of the amphibole minerals, reibeckite and grunerite; tremolite and actinolite may be either asbestiform or nonasbestiform)

Stage 2 Mesothelioma
Stage 2 mesothelioma has spread to both layers of the pleura on one side of the body only
