—This study is aimed to identify source of VOCs in Maptaphut sub-district, Rayong province, Thailand. VOCs ambient concentrations data from Pollution Control Department (PCD) were analyzed by receptor model using principal component analysis (PCA) and BTEX ratios. BTEX ratios of monitoring data in Maptaphut area were similar to ratios of roadside (Dindaeng) monitoring station which indicated that major emission source of VOCs in Maptaphut area was mobile source. Principal component analysis of the data from Health Promotion Hospital Maptaphut (HMTP) monitoring station was divided in 12 principal components (PCs) as same as PCA for roadside (Dindaeng) station. Some PC of HMTP monitoring station was contained VOCs profile similar to roadside station.
