Abstract
The aims of this study is to investigate
the possible arsenic exposure among the
maintenance engineers of wafer fabrication
facilities, in order to predict the potential
health risk after long-term occupational
exposure to arsenic. For urinary arsenic level,
average urinary arsenic levels of control
group and maintenance engineers were
32.1±25.7 μ g/L and 32.8±29.1 μ g/L,
respectively. However, by comparing the
urine arsenic concentrations before and after
workshift of three preventative maintenance
engineers, occupationally exposure to arsenic
is strongly suggested in the study site.
Meanwhile, the average of Incremental
Lifetime Cancer Risk of the maintenance
engineers for working 5 years was 3.58×10 -5 ,
within the universally acceptable level of
10 -6 ~10 -4 . Besides, the simulation results of
life cancer risk for those engineers not
wearing personal protective equipment at
work were nearly five times the risk for these
wearing. The sensitivity analysis indicated
that the input variables which are more
sensitive in the risk estimation for
preventative maintenance engineers exposure
to arsenic are concentration of urinary arsenic,
exposure frequency, and body weight.
