Abstract

This study analyzed the level and temporal variations of the air pollutants with the prevailing meteorological variables using four months dataset (April 4-July, 2022) in Osogbo, Nigeria. Multiple Linear Regression was employed to assess the relationships while Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) was adopted to identify pollutants transport path. The results revealed that PM_2.5 levels exceeded the national and international standards of and, respectively due to strong anthropogenic influences, while Ozone, CO and CH₄ showed two distinct diurnal peaks linked to traffic emissions. Also, air pollutants had weak correlations ranging from − 0.34 to 0.39 with meteorological variables and evidence from trajectory analysis highlighted both local and transboundary pollution sources, underscoring the need for seasonally tailored mitigation strategies.
