Analysis on health damage in benzene-exposed environment and relevant supervision effect in a shoe-making factory

  Objective   To understand and to improve the situation of occupational damages by benzene in a shoe making factory.

  Methods   To adopt labor hygienic investigational method.

  Results   The concentration of benzene in air was about 3.85-52.33 mg/m³ before correction and 1.28-4.01 mg/m³ after correction.Workers clinical symptoms descended after correction.Significant differences were found in symptom morbidity between the control group and contrast group(P < 0.01).Significant changes were found in female workers menses abnor mality before and after supervision(P < 0.05), and significant differences were also found between control group and contrast group(P < 0.01).The count of WBC were found to be descending compared with the contrast group(P < 0.05).The abnormality of Hb had been improved after correction, and became closer to that of the contrast group.

  Conclusion   To strengthen the supervision and detection on the occupational hygiene is a significant measure to improve the detection on the occupational damage elements and workers health in developed industrial areas.
