Cement dust exposure elevates erythrocyte sedimentation rate and total leukocyte count in workers. These hematological changes indicate potential health issues but are not linked to the duration of exposure.

Area of Science:

  • Occupational Health
  • Hematology
  • Environmental Medicine

Background:

  • Cement dust exposure poses significant health risks to workers.
  • Hematological parameters can serve as indicators of occupational exposure and disease.
  • Simple screening tests are needed for early detection of health issues in industrial settings.

Purpose of the Study:

  • To evaluate basic hematological parameters, including erythrocyte sedimentation rate (ESR) and total leukocyte count (TLC), in cement mill workers.
  • To identify a cost-effective screening method for detecting disease or severity in workers exposed to cement dust.
  • To correlate hematological changes with the duration of exposure in cement mill environments.

Main Methods:

  • A comparative study involving 50 male cement mill workers and 50 healthy male controls.

  • Participants were matched for age, height, weight, and socioeconomic status.
  • Total leukocyte count was measured using an autoanalyzer, and erythrocyte sedimentation rate was determined by the Westergren method.

    • Main Results:

    • Cement mill workers showed significantly increased mean values for erythrocyte sedimentation rate (p<0.05) and total leukocyte count (p<0.02) compared to controls.
    • No statistically significant differences were observed in these parameters based on the duration of exposure.

    Conclusions:

    • Exposure to cement dust leads to elevated erythrocyte sedimentation rate and total leukocyte count in workers.
    • These hematological changes suggest an inflammatory response or other health impacts due to cement dust.
    • The observed hematological alterations are not dependent on the length of time workers are exposed to cement dust.
