Serum TBARS was significantly increased
in the photocopier operators when compared to
the unexposed controls.
This is in tune with the high
serum TBARS among photocopier operators already
reported [13]. However, levels of 8-Isoprostane did not
show significant differences between the two groups.
TBARS may be a more sensitive biomarker than 8-
isoprostane and may be a useful tool for investigating air
pollution-related oxidative stress as discussed by
