Abstract

Introduction; Exposure to traffic air pollutants can pose a significant health effect on respiratory health among traffic policemen. Objective: The main objective of this study is to determine the relationships between personal exposure levels to PM10 and respiratory health among traffic policemen working at Traffic Police Station in Petaling Jaya, Selangor and general duty policemen attached to Police Headquarters, Putrajaya as a comparative group. Methodology; A cross sectional comparative study was conducted among 60 traffic policemen working at Traffic Police Station Petaling Jaya, Selangor and 57 general duty policemen from Police Headquarters Putrajaya as comparative group. A random sampling method been used to select on the respondents based on inclusive criteria such as age between 23 to 55 years and not less than 3 years working as traffic policemen. Questionnaire based on ATS (1978) was used to collect information on socio-demographic and respiratory symptoms. Spirometer (Spirolab 11 Model) was used to perform lung function tests. Personal Air Sampling Pump (Gillian Air Pump) was used to measure personal exposure level to PM10. Result; The median personal exposure level of PM10 among the traffic policemen was 208.33 ± 49.02llg/m3 'compared to only 49.02 ± 49.01 ug/rrr'among the comparative group. Result from Mann Whitney U test showed that there was a significant difference (p<O.OOI) between the two study groups. There was significant different in FVC (liter) with z = -5.754, P < 0.05, FEVI (liter) with z = -5.484, P < 0.05, FVC% predicted with z = -3.716, P < 0.05, and FEVI% predicted with z = -2.593, P < 0.05 between exposed group and comparative group. Discussion; Findings from this study indicated that exposure to elevated concentration level to respirable dust (PM10) is the risk factors in the development of respiratory diseases as shown by the higher prevalence of reported respiratory symptoms and the reduction in lung function among traffic policemen. Conclusion; Results from this research showed that the traffic policemen were at risk of respiratory disease, as reflected by an increase in the reported of respiratory symptoms and a reduction in lung function. Keywords: traffic air pollutants; respirable particles (PM10); respiratory symptoms; lung function
