Description
Background: The purpose of this study is to construct a job-exposure matrix for lead that accounts for
industry and work processes within industries using a nationwide exposure database.
Methods: We used the work environment measurement data (WEMD) of lead monitored nationwide
from 2015 to 2016. Industrial hygienists standardized the work process codes in the database to 37
standard process and extracted key index words for each process. A total of 37 standardized process
codes were allocated to each measurement based on an automated key word search based on the degree
of agreement between the measurement information and the standard process index. Summary sta-
tistics, including the arithmetic mean, geometric mean, and 95th percentile level (X95), was calculated
according to industry, process, and industry process. Using statistical parameters of contrast and pre-
cision, we compared the similarity of exposure groups by industry, process, and industry process.
Results: The exposure intensity of lead was estimated for 583 exposure groups combined with 128 in-
dustry and 35 process. The X95 value of the “casting” process of the “manufacture of basic precious and
non-ferrous metals” industry was 53.29 mg/m3
, exceeding the occupational exposure limit of 50 mg/m3
.
Regardless of the limitation of the minimum number of samples in the exposure group, higher contrast
was observed when the exposure groups were by industry process than by industry or process.
Conclusion: We evaluated the exposure intensities of lead by combination of industry and process. The
results will be helpful in determining more accurate information regarding exposure in lead-related
epidemiological studies.
