Table 7 shows the haematological status of the study subjects.
Hematocrit, Mean Corpuscular Volume (MCV) and
Red cell Distribution Width (RDW) were significantly
higher among photocopier operators when compared to
controls. Mixed cells (comprising eosinophils, basophils
and monocytes) were significantly lower among photocopier
operators than control subjects. No difference was
noticed in the levels of circulating total white blood cells,
lymphocytes and neutrophils between the two groups of
subjects. Hematological status among non smoking
photocopier operators and controls was not different from
that of photocopier operators and controls. This suggests
that smoking does not significantly influence hematological
status in this study population.
