【 摘 要 】

Problem statement: Air Quality Monitoring (AQM) station at Kasetsart University, Si Racha Campus, Thailand, wasroutinely monitor the annual concentrations and analysis the emission sources of the air pollutants in the areasince 2007. The level of concentration CO, SO₂, NO_x and O₃ were measured. PM₁₀ concentration was measured by mean of TOEM method. The PM₁₀ and TSP (manifold) filters were collected for the measurement of heavymetals adsorbed in the particulate by ICP-AES techniques. Scanning Electron Microscopic (SEM) and EnergyDispersive Spectrometric (EDS) techniques were used to identify the morphologies and elemental compositionsof particulate matters from the PM₁₀ and TSP filters. Approach:The annual concentrations of all pollutants were almostreal-time reported from July 2007-2008. The O₃ concentrations are higher than the standard level (100 ppb) in July 2007 and April 2008 with the value of 109 and 114 ppb, respectively. Average PM10 concentrations arehigher than the standard level (120
