Abstract
In the past few decades, the level of air pollutants enhancing ambient air pollution rose due to enhanced industrial production and human activities. However, there is limited number of research on the spatio-temporal variation, interpolation, overlay analysis for vulnerable areas, and formulation of technical findings and policy implications for ambient air pollution. The main objective of the study was to geospatially map the ambient air pollution and susceptibility of urban centers in Davao City. Data were analyzed using the Geographic Information System (GIS). The four parameters; particulate matter 10 (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), and ground level ozone (O3) from the five air quality monitoring stations (DC Stations 2, 7, 11, 14, 15) in the city were interpolated and mapped using the Inverse Distance Weighting method. Based on the results, most of the monitoring stations have not exceeded the National Ambient Air Quality Guideline Value (NAAQGV) but greatly exceeded the Global Ambient Air Quality Guideline Value (GAQGV) of WHO. Majority of the city is highly vulnerable to ambient air pollution. Structures around Station 14 or Toril Open Park Area Station are among the most exposed to ambient air pollution, has the highest number of affected structures, and is classified as highly vulnerable to ambient air pollution. With this, the results suggest that policies that guarantee clean ambient air must be strongly enforced in the community due to the problem of ambient air pollution.
