Title:

From 1958, this historical image was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Heal

Description:

From 1958, this historical image was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). It depicted industrial medicine in action, and was used in the U.S. Public Health Service (USPHS) publication, no. 601, entitled, 'Pneumoconiosis in Diatomite Mining and Processing', 1958. The photograph showed an Industrial Hygiene Division (IHD) investigator taking workplace air samples, in order to monitor air quality. This publication featured results of the Lompoc, California study of diatomaceous earth's negative health effects. The substance is a non-chemical pest control, consisting of the fossilized calcific remains of free floating algae called 'diatoms'. The naturally occurring, soft, chalk-like sedimentary rock material easily crumbles into powder, so its fine, but abrasive properties make it useful as a mechanical pesticide.
