Investigation of the Pulmonary Function Level in Municipal Solid Waste Collectors: A Case of Bandar Abbas City During 2015 - 2017

Abstract

Background: In Iran, most of the cleaning processes are performed manually in urban areas. Sweepers are exposed to respiratory pollutants, infectious substances, and other hazardous substances such as chemicals, animal feces, and sharp objects during improper disposal of waste. Respiratory pollutants in these occupations can cause inflammation and damage to the respiratory system. Moreover, prolonged exposure to respiratory pollutants in the workplace can reduce lung function and cause numerous health problems. Objectives: This study aimed to examine the effect of workplace exposures of municipal solid waste collectors on the reduction of the pulmonary function level. Methods: This retrospective cohort study was performed on 198 municipal solid waste collectors aged 18 to 55 years who were employed in this profession for at least two years. The sampling method was census, and demographic data were extracted from occupational examination records. Results: Examining the relationship between pulmonary function decline and the studied variables showed a significant relationship between smoking and reduction of FVC, FEV1, and FEF25 -75. However, no significant relationship was observed between dust exposure and pulmonary function decline. Conclusions: No significant relationship was observed between pulmonary function loss and occupational dust exposure in municipal solid waste collectors. This means that the occupational exposure of these individuals was not severe enough to cause pulmonary function loss.
