Abstract
The present study was initiated to
evaluate the overall effects of lead exposure
factors on the blood lead level by applying
the structural equation model. Total 96 out of
113 assembly workers from a lead battery
plant were recruited. Lead samples in air, on
sleeves, gloves, hands, cheeks, and lips, etc.
were applied as external lead exposure.
Venous blood samples were obtained for lead
determination during workers’ annual
physical examination. Structured
questionnaire was administered to collect
demographic data, work history, personal
hygiene behaviors, use of personal protective
equipment, etc. Results of structural equation
model demonstrates that blood lead level was
found strongly associated with lips lead
loadings, sweat-wearing frequency, and
inadvertent contact, while airborne lead only
has indirect effect on blood lead level
through lips lead loadings. Since blood lead
levels might be influenced by various
cofounders, it is concluded that structural
equation model is an appropriate alternative to evaluate worker’s lead exposure pathways.
Also, as a result of the present study, it is
recommended that further efforts on lowering
lead battery workers’ blood lead levels must
pay more attention to the management of
house-keeping and workers’ personal
hygiene.
