Amosite
A type of asbestos in the amphibole group; it is also known as brown asbestos.

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

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 1 Mesothelioma
Stage 1 mesothelioma affects one layer of the pleura only. It may have grown into the covering of the heart (pericardium) and the diaphragm

Crocidolite
A type of asbestos in the amphibole group; it is also known as blue asbestos.

Pleural effusion
A pleural effusion is an accumulation of fluid between the layers of the membrane that lines the lungs and chest cavity.

Hazardous Air Pollutants
Air pollutants that are not covered by ambient air quality standards but which, as defined in the Clean Air Act, may reasonably be expected to cause or contribute to irreversible illness or death. Such pollutants include asbestos, beryllium, mercury, benzene, coke oven emissions, radionuclides, and vinyl chloride.

Mesothelioma
A rare malignant tumor of the lung membrane which lines the chest and abdominal cavity. Malignant mesothelioma is a cancerous tumor of the pleura (lining of the lung and chest cavity) or peritoneum (lining of the abdomen) that is almost always caused by sustained exposure to asbestos.

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

Adenocarcinoma
Adenocarcinoma of the lung is a type of lung cancer. Like other cancers, adenocarcinoma is the growth of abnormal cells. These cancerous cells multiply out of control, and form a tumor. As the tumor grows, it destroys parts of the lung. Eventually, the tumor's abnormal cells can spread (metastasize) to other parts of the body, including the brain.
