    Abstract: Sawdust particulate matter collected from different parts of Akure metropolis, Nigeria were analyzed for heavy metals using flame atomic absorption spectrophotometry. Particulate samples were collected between May and December 2004 gravimetrically. Total suspended particulate (TSP) concentrations were between 2.28-11.74g/m<SUP>3</SUP> (dry season) and 1.66-9.10g/m<SUP>3</SUP> (wet season). During both seasons, Pb, Mn and Zn were enriched in the samples. Pb/Zn ratio was generally highest in the highways it varied thus: 1.92-2.48 (wet season) and 1.96-2.27 (dry season). There were significant variations and correlations for interaction of seasons and distance for all the locations. From the results there is a great need to discourage the citing of residential areas near sawmills, this is just to minimize the hazardous effects on public health.
