<![CDATA[The dense volume of traffic on the Pitameh Tanjung Saba highway has the potential to increase air pollution. The purpose of this study was to analyze the risk of respiratory tract disorders for traders due to exposure to total suspended particulate dust in ambient air on Highway Pitameh Tanjung Saba, Lubuk Begalung District, Padang City in 2023. This type of research uses a descriptive analytic design with an environmental health risk analysis approach. Which was carried out from January to May 2023. The sample for this study was dust measuring ≤100 µm taken at 3 measurement points and a sample of 43 traders. The research data were obtained by measuring dust levels and interviews using a questionnaire. The results of the study stated that the TSP dust content at point 1 which was located at the Indarung by-pass traffic light intersection was 242.42 µg/m3, at point 2 which was located in front of the Muhammadiyah Great Mosque of 211.44 µg/m3 and at point 3 which was located at Intersection Pitameh of 232.39 µg/m3 . Based on the calculation of the TSP exposure risk analysis performed, it can be seen that as many as 8 respondents to real time exposure and 1 respondent to life time exposure with an exposure duration of 30 years had a risk characterization value of > 1 and as many as 74.4% experienced symptoms of respiratory tract disorders while trading in Highway Pitameh Tanjung Saba, Lubuk Begalung District, Padang City.]]>
