Caption:
From 1958, this historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), and depicted four industrial hygienists who were using microscopes in order to count diatomaceous dust particles found in samples collected during an occupational health study in Lompoc, California. The study findings were included in a U.S. Public Health Service Publication No. 601, entitled, “Pneumoconiosis in Diatomite Mining and Processing”, 1958. Inhaled dust or other airborne particulate materials containing silica that is deposited in the lungs, will cause the lung tissue to react by creating generalized nodular fibrotic changes, and is known as pneumoconiosis, which is also known as pneumosilicosis, or grinders’ disease.
