Epidemiological-environmental study of lead acid battery workers : I. Environmental study of five lead acid battery plants.
Environ Res 1984 Oct; 35(1):1-10
An epidemiological study of workers in lead (7439921) acid battery factories was conducted. Stibine (588590) and arsine (7784421) samples were collected on charcoal tubes and analyzed by atomic absorption spectrophotometry. Work room air was collected and measured for lead and sulfuric-acid (7664939). Stibine concentrations averaged 0.44 milligram per cubic meter and arsine averaged 0.042 milligram per cubic meter. The highest concentrations of the two compounds occurred in the element formation area. The average diameter of sulfuric-acid mist was 5 micrometers. The relative humidity inside the factories was low; it was likely that sulfuric-acid particles stayed within the respiratory tract and did not penetrate deep into the lung. Acid concentrations were usually higher in workers in the charging and forming areas of the factories, but were below the concentration needed to cause respiratory passage irritation or dental damage. The average air lead concentration was 0.072 milligram per cubic meter. The authors conclude that lead concentrations found in the acid battery factories are above OSHA standards and warrant better control methods. (Part 1 of 3)
