This study examined the relationship between total arsenic levels in hair of employees in a semiconductor fubrication facility and job responsibility, a surrogate variable for arsenic exposure potential.
Maintenance personnel who regularly worked in equipment cleaning areas were assumed to have higher potential for occupational exposure than other employees.
Occipital scalp hair samples were collected form 30 maintenance personnel supervisors, and equipment engineers with high, medium, and low potential for exdposure and from 26 administrative employees.
Total arsenic in hair was measured by atomic absorption spectroscopy with hybride generation.
Workplace air and wipe samples were analyzed to verify differing exposure potential in fabrication and administrative areas.
Subjects completed written questionnaires to identify possible nonoccupational sources of arsenic.
Mean hair arsenic in two of the three groups working in or near fabrication areas was slightly higher but not statistically different from that of administrative controls.
Eliminating smokers, only the maintenance group regularly assigned to fabrication areas was higher than administrative controls but still not statistically different.
A regression analysis of all factors inidcated that sex, tapwater consumption, and dietary habits were significant contributors to arsenic in hair.
