Breathing zone and general room air samples were collected and analyzed for arsenic (7440382), copper (7440508), lead (7439921), molybdenum (7439987) and selenium (7782492) content at the Kennecott Smelter (SIC-3331) in Garfield, Utah, on October 25 and 26 and December 13 and 14, 1978; and January 8 to 11, 1979 at the request of a representative from Local 4347, U.S. Steelworkers, on behalf of approximately 150 affected workers. Medical evaluations were conducted for 40 workers. Air samples were analyzed by atomic absorption spectroscopy. Concentrations of lead, arsenic, and copper exceeded the OSHA standards of 0.05, 0.01, and 1.0 milligrams per cubic meter (mg/m3), respectively. No overexposures to molybdenum or selenium were found. Medical evaluations confirmed respiratory system complaints, including nasal and lung irritation with or without breathing difficulties. Ten men had unacceptably high blood-lead levels. The authors conclude that approximately 20 percent of the workers were overexposed to arsenic, lead, and copper, and a health hazard did exist in the reactor areas. The most serious health hazard was an inadequate respirator program. Recommendations resulting from the evaluation included environmental and engineering control improvements, use of personal protective equipment, housekeeping improvements, and careful medical surveillance.
