The present study explores the ability of different plant species in Rourkela to capture PM of varying size fractions from air. The amount of PM<sub>10</sub> and PM<sub>2.5</sub> deposited on the foliar surfaces and trapped in epicuticular waxes of plant species were segregated and quantified by separate gravimetric analyses, from three different sites in Rourkela, and over three different seasons. Plants of all species were found to accumulate PM of large and coarse fraction sizes efficiently. Depending on the location and season, it was found that the quantities of foliar and in-wax PM varied among the studied plant species. Among the three seasons, the highest amount of PM accumulated by the plant species was recorded in the winter season measuring 90.102 × 10<sup>- 4</sup> g/cm<sup>2</sup>.
