The primary purpose of the study was to assess the quality of air, in terms of dust density, in Davao City and also to determine whether traffic vehicle density could be its significant correlate. Descriptive correlation was used in the study. The traffic vehicle influx measured in several selected streets of Davao City was paired to the dust density of the surrounding air in the sites to explore the linear relationships of these two variables. The research sites included 20 selected busy streets. Findings revealed that the traffic vehicle influx describe a growing city with busy streets due to the number of establishments and commercial centers. The dust density has gone beyond the limit for what is considered acceptable. Moreover, the investigation established a significant correlation between traffic vehicle influx and dust density.
