Abstract
The purpose of this study was to evaluate the total suspended particulate matter (TSP) levels and inhalable paniculate (IP) (<10μ) levels at four sites in Riyadh, Saudi Arabia. The TSP was evaluated by using standard high volume air samplers and the IP by using circular jet cascade impactors. The average outdoors TSP for 56 samples taken at the four sites was 580 μ.g/m3. The average outdoor back‐ground TSP outside the city of Riyadh was found to be 103 μg/m3. The average TSP for the 56 indoor samples at the same four sites was 194 μ.g/m3. The I/O ratios for TSP ranged from 0.09 to 0.71. The average outdoor IP for the 59 samples taken at the four sites was 240 μg/m3. The average indoor IP for the 59 samples at the four sites was 106 μg/m3. The I/O ratios for IP ranged from 0.21 to 0.59. The average geometric size for IP outdoors was 1.44 μm, while that indoor was 1.14 μm.
