  Background : Occupational exposure to dust generated in the process of carpet weaving which can lead to pulmonary complications. The aim of this study was to investigate the association between exposure to carpet dust size and parameters of lung function.

  Method : This retrospective case-control study was performed on 95 carpet weaver City Khomein. The total exposure inhaled carpet dust using air sampled was determined by gravimetric method. Spirometry parameters including FVC, FEV1, PEF and FEF25-75weaving of pulmonary function and related parameters such as temperature and humidity in the working environment were collected. The total dust exposure associated with lung function parameters were studied.

  Result : Results showed that the total dust concentration in the study group vs. 2.47 ± 4.69 mg per cubic meter, compared with the control group (1.33 ± 2.89 mg per cubic meter) were significantly higher. Comparison of total dust concentration in lung function observed a significant relationship between these two parameters (P-value = 0.321). Environmental parameters such as humidity, temperature and ventilation of the workshops showed that the workshops were in need of reform to reduce dust. Studies showed an inverse relationship between the experience and FVC, FEV1 and PEF, and FEF25-75 criteria exist indices decreased with increasing years of work provided.

  Conclusion : These results indicate that the survival of the project study area, contact Kelly carpet dust as an occupational risk factor, there is still a high rate.
