However, when the exposed population was dichotomized
for benzene exposure, a significant ( p = 0.018) correlation of CAs with benzene exposure was found. The analysis of SCE
data highlighted a significant increase of cells with more than 6 exchanges (HFCS), corresponding to the 75” percentile of the
overall distribution, in fillingstation attendants (relative risk (RR) = I .3. 95% CI = I. l-l .5) in comparison with controls.
