    • The air particulate matter was measured at two heavily congested roads in Bangkok during the dry season in 2006. Air samples of both coarse particulate matter (PM10) and fine particulate matter (PM2.5) were collected by individual, low-flow personal air samplers. These data are compared with the observations made by the Pollution Control Department (PCD) at the Ladphrao and Dindaeng roadside stations and found to be highly correlated with R2 = 0.86 and 0.90 for PM10 and PM2.5, respectively. The PCD observations were measured by Beta-ray attenuation and TEOM (R & P single channel. Next, numerical simulations of the PM10 concentration were made by the The Air Pollution Model (TAPM, version 3.0). An emissions inventory for PM10 was developed based on the local traffic records near the two stations. A background urban concentration was estimated from an average of PCD sites across Bangkok during the early hour mornings of 02:00-04:00 AM. These simulated concentrations with this rather simple emissions inventory, show enough skill to allow for TAPM to be used as viable tool for the planning of future urban development.
