title: Epidemiological-environmental study of lead acid battery workers. I. Environmental study of five lead acid battery plants.
abstract: Industrial hygiene measurements were taken at five lead acid battery plants. The average of all personal samples for H2SO4 was 0.18 mg/m3 with a range of "nondetectable" to 1.7 mg/m3. Highest levels of acid were found in the charging and forming areas of the plants. Stibine and arsine were also detected in the charging and forming areas (means = 0.44 and 0.042 mg/m3, respectively). Arsenic in particulate form was also detected, but levels were low (means = 0.00083 mg/m3). The average mass median aerodynamic diameter of the acid mist as measured by cascade impactors was approximately 5 micron. Air lead results were variable with an overall average of 0.072 mg/m3 and a standard deviation of 0.11 mg/m3.
