Particulate matter was captured from five different sites using SKC Air Check gravimetric sampler Model 21-5000 serial no 20537 and a glass fibre filter between the months of December 2008 and April 2009. The glass fibre filters were analysed for nine trace metals – Fe, Cu, Zn, Cd, Mn, Pd, Ni, Cr and Co (by Atomic Absorption spectrophotometric (AAS). The data obtained were subjected to factor analysis. Enrichment factors of various elements relative to crustal abundance for the air filters indicate that input of the majority of elements is due to crustal resuspended soil induced by wind and traffic. The element Cd was moderately enriched. The mean ambient temperature was in the range of 26.400C, the relative humidity was in the range of 70.00-72.60% and the mean wind speed was in the range of 0.13-0.34m/s.
Key words: Trace metals, Enrichment Factor, Atomic Absorption Spectroscopy, Total Suspended Particulate Matter, Rural area.
