摘要

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.
