A period prevalence study examining concurrent PbB, ZPP and Hgb test values from 236 employees of one lead-acid battery manufacturing plant over a six month period was conducted. Fifty-six job categories in the plant were grouped on the basis of proximity and/or similarity of lead exposure. Diagrams of plant layout, the process flow chart, work order, department numbers and biological and environmental data from earlier plant surveys were used in dividing the jobs into five exposure index groups. Length of service with the company was calculated to provide an indication of the duration of occupational exposure to lead. Length of service in the exposure index group was calculated to provide information regarding the duration of exposure as measured by the type of job. Recommendations were made that: 1) a single set of tests not be evaluated in isolation but considered as part of the overall pattern of an individual's laboratory data; 2) ZPP be required by OSHA for periodic monitoring; 3) use of both the PbB and ZPP tests is necessary for biological monitoring at PbB levels less than or equal to 55 ..mu..g/dL; and 4) a PbB value of 40 ..mu..g/dL is a good level to use in determining who will have more frequent biological monitoring for the purpose of OSHA compliance.
