Abstract

Directly inhaled pollutants may cause people to have highest exposure to air pollution. This situation occurred among people who commute by active traveling. Exposed to high levels of pollution could cause disruption of the normal functioning of respiratory system by affecting not only the lungs, but also include larynx, trachea, pharynx and respiratory muscles. Objective: To determine the association of traffic related air pollution (TRAP) exposure and respiratory symptoms among pedestrian around campus area. Method: A cross-sectional study was conducted by measuring three main traffic-related air pollutants (TRAP); PM2.5, PM10 and ozone during walking along designated sampling routes around Universiti Putra Malaysia (UPM) at different rush periods (morning, afternoon and evening) (n 32). A set of questionnaires was distributed among students who were actively commute around the campus. Measurements of PM2.5, PM10 and ozone (O3) were taken using SidePak, DustTrak and Aeroqual Series 500 and carried by the researcher. Motor vehicles traffic count were conducted simultaneously with the measurement. A set of standardized questionnaires adopted from International Union Against Tuberculosis and Lung Disease) were distributed among pedestrian (n=45) to obtain respondents' background information and their respiratory symptoms. Result: There was significant association of TRAP exposure and some of the respiratory symptoms among pedestrian in UPM campus. PM2.5 and PM10 were statistically significant with symptoms of wheezing with p-value 0.017 and 0.019 while shortness of breath with p-value of 0.040 and 0.039. While O3 concentration did not showed significant difference with any of the respiratory symptoms studied. Traffic count result showed the highest number of vehicles using Road 1 and 2 were during morning rush hour. Conclusion: In conclusion, pedestrian were exposed to high levels of TRAP and it was associated with symptoms of respiratory problems. Keywords: Traffic-Related Air Pollution (TRAP), Respiratory Symptoms, Pedestrian
