Cement dust exposures has been reported to result in significant occupational health problems and long term
complications and symptoms. In this present study we monitored some haematological parameters; Packed Cell Volume
(PCV), Haemoglobin (HB), Erythrocyte Sedimentation Rate (ESR), White Cell Count (WBC) and Platelet (PLC) count of
100 workers (mean age 37.42 ± 10.14 years) who were occupationally exposed to cement dust (mean years of exposure
9.9 ±5.6 years). Fifty age and gender matched non -exposed individuals were monitored as controls. The PCV was
significantly lower among exposed subjects compared to non-exposed (31.1 ± 3.3 versus 40.7 ± 3.8), p=0.001. Platelet,
WBC and ESR were significantly higher among exposed subjects (262 ± 57.2, 15.5 ± 11.9 and 13.2 ±1.7) compared to
non-exposed controls (204 ±36.7, 12.9 ± 10.2 and 10.4 ± 1.3) respectively. We observed an age dependent higher PCV
and ESR among non-exposed controls as well as a lower age-related lower WBC and platelet count. We observed a
significant positive correlation between age of exposure and WBC (r= 0.48). Our finding does indicates that occupational
exposure to cement dust may have a negative impact on the haemopoietic function.There is need for cement producing
companies to provide appropriate personalprotective equipment for their staff as ensure that staff are compliant in the use
of these equipment. There is also the need to periodically monitor the health and well being of staff exposed to cement
dust.
