This study investigated the air quality index patterns for PM 2.5 and PM 10 in the airshed of a haulage vehicle park located around a major highway connecting Lagos, the commercial centre of Nigeria to its other parts. Measurements of PM 2.5 and PM 10 were done at five different sub-parks using the aerosol mass monitor GT-331 by Met one instrument. The measured concentrations ranged between16.07-29.95 μg m −3 and 125.95-433.08 μg m −3 for PM 2.5 and PM 10 , respectively. The air quality index (AQI) within the park with respect to PM 2.5 could be described as moderate but unhealthy within at least two sub parks when PM 10 is considered; hence, the health of vulnerable people could be at risk. This study establishes that vehicular activities at the park could have significant impact on the park's ambient air quality, thus calls for appropriate regulatory measure to protect commuters plying the major highway around the park.
