Abstract: An evaluation of the seasonal variations of ambient Particulate matter was carried out in Warri and Port Harcourt Metropolis (Nigeria). The sampling was performed with well calibrated equipment (A MultiRAE PLUS (PGM – 50) a programmable Multi Gas monitor with an electrochemical sensor). Parameters assessed were particulate matter with 1µm, 2.5µm (PM2.5), 7µm ( PM7), 10µm (PM10) and Total suspended particulate (TSP). At Warri TSP ranged from 586.8 – 672.8 µg/m3 while Port Harcourt had TSP value that ranged from 611- 725.0 µg/m3 for the dry season (October- March). The wet season (April – September) data were generally low for both study locations. Pollutants, typically TSP and others showed remarkable and more often significant seasonal variation with months of the year. The concentration of TSP in dry season being statistically higher than those of wet season, as [tstat (48.82782516).05 > tcritical one tail (1.734063592)0.05]; and P(T t-critical one tail (1.734063592)0.05 and P(T t critical one tail (1.734063592)0.05 and P(T t critical one tail (1.734063592)0.05 and P (T t – critical one tail (1.734063592)0.05 and P(T t-critical one tail (1.734063592)0.05 and P(T
