Occupational environmental exposure
Arsenic
Arsenic is classified as an IARC Group 1 carcinogen and is a cause of lung cancer. Workers can be exposed to arsenic through work with some pesticides or in copper smelting. Asbestos
Asbestos is a mineral which was extensively used in the United States to fireproof buildings and textiles, among other items, in the 1950s-1980s. Workers are frequently exposed to asbestos during demolition and renovation work, which can cause asbestosis and/or mesothelioma. Asbestos exposure can also cause pleural effusion, diffuse pleural fibrosis, pleural plaques, and non-mesothelioma lung cancer. Smoking greatly increases the lung cancer risk of asbestos exposure.Residents and workers of asbestos mining centers such as the town of Asbest, Russia experience dangerous exposure to asbestos and asbestos dust. BCME
BCME (Bis(chloromethyl) ether) is associated with small cell lung cancer in workers who have been exposed. Exposure can occur via direct manufacture of BCME or its presence as a byproduct.
