Description:Environmental and breathing zone samples were analyzed for inorganic arsenic (7440382), stibine (7803523), antimony (7440360), and sulfuric-acid (7664939) at Johnson Controls, Incorporated (SIC- 3691), Owosso, Michigan in November 1983 and April 1984. The evaluation was requested by the union to assess exposures to lead (7439921) and other substances. Concern was expressed about apparent physiological discrepancies between blood lead and zinc- protoporphyrin (ZPP) concentrations in certain workers. Company lead monitoring and blood lead/ZPP data was reviewed. Urine samples were obtained from 49 workers and analyzed for arsenic. The company respirator program was reviewed. Eleven percent of 675 lead breathing zone samples exceeded the OSHA standard of 50 micrograms per cubic meter. Highest exposures were among janitor and maintenance workers. Arsenic, stibine, and antimony exposures were below the OSHA standards. Sulfuric acid was not detected. No pattern of medically unexplained discrepancies between blood lead and ZPP concentrations was detected. Urine arsenic concentrations were within the normal range. Improper use of respirators was observed. The authors conclude that there is no definite pattern in the company blood lead/ZPP data. Maintenance and janitorial personnel have the greatest potential for lead exposure. Recommendations include keeping worker blood ZPP concentrations from rising excessively and improving the respirator program.
