• Description:
  Worker exposure to dust, free silica (7631869), and fluoride concentrations were determined at facilities of the phosphate (14265442) industry (SIC-5191) in Polk County, Florida beginning on October 14, 1957. The survey resulted from a request from the President of the International Chemical Workers' Union to the Surgeon General of the Public Health Service. Partial medical records were maintained and all employees received preemployment physicals. The dust in the dry mill area was well under 5 percent in free silica content; fluoride concentrations of airborne dust at storage and shipping operations in this area at times considerably exceeded the American Conference of Governmental Industrial Hygienists threshold limit value (TLV) of 2.5 milligrams per cubic meter. Over half of the atmospheric fluoride concentrations at a chemical facility exceeded the TLV. The authors recommend that environmental and medical studies be conducted in the phosphate industry to determine the extent and magnitude of potential health hazards. The studies should include air sampling, routine urine fluoride analyses on workers in dry mill and chemical facility areas, and physical examinations of workers. [Description provided by NIOSH]
