The main objective of this study is to determine the relationships between personal exposure levels to PM2.5 and respiratory health among traffic policeman working at Traffic Police Station in Kuala Lumpur and general duty policeman attached to Police Headquarters, Bukit Aman as comparative group. Methadology: A cross sectional comparative study was conducted among 50 traffic policeman working at Traffic Police Station Kuala Lumpur and general duty policemen from Police Headquarters Bukit Aman as comparative group. A purposive sampling method was used to select on the respondents based on inclusive criteria such as age between 25 to 60 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 systems. Spirometer (Spirolab II Model) was used to perform lung function tests. Personal Air Sampling Pump (AirCheck 52) was used to perform lung function tests. Personal Air Sampling Pump (Aircheck 52) was used to measure personal exposure level PM2.5. Result: The mean exposure level of PM2.5 among the traffic policemen was 22.33±8.54 µg/m3 compared to only 5.60±4.29 µg/m3 among the comparative group. There was significant different in FVC (liter) with t =-2.272, p <0.05, FEV1 (liter) with t=-2.469, p< 0.05, FVC% predicted with t= -2.046, p< 0.05, FEV1% predicted with t =-2.213, p<0.05 and FEV1/FVC% predicted with t = -2.365, p< 0.05 between the exposed group and comparative group. Discussion: Finding shows that there were significant relationships between the working duration (years) and the lung function parameters among both exposed and comparative group. Finding from this study indicated that exposure to elevated concentration level to traffic related air pollutant is the risk factors in development of respiratory disease as shown by the higher prevalence of respiratory systems and the reduction in lung function among traffic policemen. Conclusion: The result from this research showed that the traffic policemen at risk of respiratory disease, as reflected by an increase in the incidence of respiratory systems and lower lung function. | ||
