Abstract
Environmental and breathing zone samples were analyzed for metal fume particulates, polynuclear aromatic hydrocarbons (PNA), hydrogen- sulfide (7783064) (H2S), and carbon-monoxide (630080) (CO) at the United States Assay Office (SIC-9999), San Francisco, California in March and April 1983. Evaluation was requested out of concern for exposure to metal fumes from the melting of coins and possible work related headaches, nausea, and kidney disease. Twelve workers were interviewed and the medical records of six employees working in the melting room were reviewed. Metal fumes, CO, and H2S concentrations were below all relevant standards. Two PNA compounds, fluoranthene (206440) and pyrene (129000), were detected at concentrations of respectively. There is no current standard for fluoranthene or pyrene. No pattern of medical symptoms or physical findings that were work related were found. The authors conclude that no overexposure to environmental contaminants has occurred. Recommendations include substituting the quenching oil used as a mold release with a sodium-silicate wash to eliminate PNA exposure and using an appropriate respirator in the melting room.
