Abstract

Urban workers are susceptible to traffic-related air pollution (TRAP) exposure that can increase the prevalence of respiratory health symptoms among them. PM2.5 was the main pollutants emitted from vehicle emission during fossil fuel combustion. This will influence TRAP level in an urban environment. This study was a cross-sectional comparative study that conducted among traffic policemen (n = 160) and office workers (n = 149) in Klang Valley. The respondents' information and respiratory health symptoms were gathered using a set of questionnaire that adapted from American Thoracic Society (ATS). The air samples for personal exposure and workplace exposure were collected during working hours. The average PM2.5 levels for traffic policemen was 87μg/m3 (personal) and 86μg/m3 (workplace). The average PM2.5 levels for office workers was 28μg/m3 (personal) and 26μg/m3 (workplace). The statistical results of PM2.5 levels between both groups are significant difference for personal exposure (z = -15.685, p < 0.001) and workplace exposure (z = -14.519, p <0.001). The Chi-Square test result indicates that there is a significant difference in cough episode between both groups. This study concludes that exposure to high levels of PM2.5 from TRAP would increase the prevalence of respiratory health symptoms among urban workers.
