【 摘 要 】

Previously, the capture of suspended particulate matter focused on the totalsuspended particulate matter, until recent research into the health impacts of suspendedparticulate matter suggests that minute particles that have toxic substances adsorbed ontotheir surface are insidious and deleterious for human health and vegetation. The Inhalablefraction and respirable fraction were captured between the month of May 2009 to October2009 using SKC Air Check Gravimetric Sampler- Model 210-5000 serial No. 20537 andrespirable foam for I.O.M sampler. The elemental composition (Co, Ni, Zn, Cu, Fe, Pb,Cr, Mn and Cd) were analyzed by using Atomic Absorption Spectrophotometric (AAS).The data generated were subjected to descriptive analysis. In inhalable fraction,theenrichment factor ranged from 1-73.3 while in respirable ,it was 1- 72.9.Lead had thehighest mean concentration in both inhalable and respirable fraction. From the enrichmentfactor Cd was highly enriched while Pb was moderately enriched. Co and Ni were belowdetection limit in both inhalable and respirable suspended particulate matter.
