Quarterly concentrations of ambient particulate matter mass ranges PM1, PM2.5, PM7, PM10, and Total Suspended Particles (TSP) were measured in a major cigarette manufacturing company in Ibadan, southwestern Nigeria. The samplings were carried out in both the indoor and outdoor environment of the study location. During the study, the ambient measured microclimatic parameters agreed with the weather historical data of the area. Measured and extrapolated 24-hr concentration of the PM2.5,PM10, and TSP were compared with  the World Health Organization, Federal Ministry of Environment (FMENV), and the World Bank Standards. Particulate matter (PM) was measured with GT-331 Particle Mass Monitor while weather tracker Kestrel 4500 was used for the measurements of microclimatic parameters.  It was found that some of the PM ranges measured fall within standard while some exceeded the set standards. The highest measured concentrations of the particulates were noticed in the first quarter which could be attributable to the prevailing microclimatic conditions during the quarter. PM10 and TSP gave the highest measured and 24-hr extrapolated concentrations for all the quarters in the indoor and outdoor environments. Seasonal/quarterly variation and compliance with cleaner practice were found to be associated with PM10 and TSP concentration.
