ASSESSMENT OF THE CURRENT STATUS OF CO EMISSIONS FROM TRANSPORTATION ACTIVITIES IN PHU HOA WARD, THU DAU MOT CITY

Abstract

This study was conducted to evaluate the level of carbon monoxide (CO) pollution generated by transportation activities in Phu Hoa Ward, Thu Dau Mot City, focusing on major roads and urban areas. The research team applied Geographic Information System (GIS) technology using QGIS version 3.34.2 to construct an interpolated CO pollution map at 39 monitoring locations. The interpolation was performed using the Inverse Distance Weighting (IDW) method to visualize CO-affected areas across three time frames (morning rush hour, midday off-peak, and evening rush hour) during the beginning, middle, and end of the week. The results indicate that most arterial roads exhibit CO concentrations exceeding the national standards during the morning and evening rush hours. Several urban areas, however, maintained CO levels within the permissible limits as defined by QCVN 05:2023/BTNMT – National Technical Regulation on Ambient Air Quality. Furthermore, the generated CO pollution maps revealed that the Tan Van –My Phuoc intersection (Phu Loi Street intersecting with Tan Van – My Phuoc Road) consistently recorded the highest CO concentrations across all three time periods (morning peak, midday off-peak, evening peak). The Phu Hoa Hang Bong Market area, characterized by high population density, also exhibited elevated CO levels, while the Moi Ba Relic Site area, with sparse population, recorded the lowest CO concentrations.
