Ozone Exposure Intake in the Ambient and the Impairment of Pulmonary Function to among Street Sweeper Workers in Jagakarsa District, South Jakarta, Indonesia

This study aimed to analyze the association between ozone (OSUB>3) exposure and the impairment pulmonary function of the highway sweeper workers

This research applied a cross-sectional study design. The respondents of this study were 78 respondents and total samples of pulmonary function measurement were 30 people who have been working for more than 5 years which derived from 6 Villages in Jagakarsa. The measurement of O₃ using an ultraviolet ray absorption method. The respondent data collection and impairment pulmonary functions were conducted through questionnaire distribution, body height and weight, also spirometry measurement. The data analysis was conducted with univariate, bivariate and multivariate analysis.

The average of measurement within 3 days of O₃ concentration was 193.96 ug/m 3 . The respondents intake average value is 0.000296 mg/kg/day; respondents age of ≤ 43 years old are 42 people (53.8%); mostly wearing mask when working, there are 68 people (87.2%); respondents who have smoking habit are higher which are 51 respondents (65.4%); most of the respondents who are not doing physical activity are 42 people (53.8%). From 30 respondents, 17 respondents (56.7%) have impaired pulmonary function. The bivariate analysis result shows that smoking habits (p=0.011) and physical activities (p=0.049) have a relation to the impaired pulmonary function. According to the multivariable analysis, the smoking habit has the most influence on the impaired pulmonary function with the Odds Ratio OR =7.779 (95%CI= 1.099-55.054).

The study result shows that there is no significant relationship intake of ozone exposure in the ambient and impaired pulmonary function. There are other factors that may reduce pulmonary function which are ages, smoking habits, and physical activity.
