|Description:||From 1958, this historical image was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). The design of this U.S. Public Health Service Publication (USPHS) title page, No. 601, entitled, “Pneumoconiosis in Diatomite Mining and Processing”, published that year, depicted just a few of the many forms in which diatoms may be found. The publication featured the results of the 1953-1956 USPHS study of miners’ who’d been exposed to airborne particulates in diatomaceous earth mining and processing plants, and the resultant negative health consequences including respiratory, ocular, and dermal disorders. The study cohort involved participants from three different western states.|
The NIOSH Historic Photo Collection began as the “picture file” of the Industrial Hygiene Division of the U.S. Public Health Service (USPHS), c. 1930-1960. It is a unique collection of mid-20th Century images of American workers and workplaces and documents occupational safety and health research of that era. The collection consists of approximately 1,000 original photographs and schematic drawings.
