One of the critical environmental issue ofa local pottery production industry is an airpollution emissionfrom burning process without control systems. Thismay seriously cause health and environmental impacts. This study analyzedparticulate matter (PM) concentration and its metalcompositionreleased from the wood-fueled burning process of the pottery production.Prediction of the pollutants dispersion was also performedusing AERMOD model.A potteryfactory in Muang district, Ratchaburi province was selected as a case study. PM samplingwas performed at stack’s furnace throughout the burning process in two production cycles.PM were quantified by means of gravimetric method. A number of 15 metalelementsin PMwere then analyzed by using the ICP-OESinstrument. The results found that averaged PM emission was 131mg/m3. There were totally 8 metalspeciesfound as follow:Fe, Al, Zn, Mg, Ni, Cr, Mn and Cu.The model’s dispersion estimationsshowedPM alignments agreed with wind rosesof the study area.The 24-hours-highest PM concentration(averaged both of the two production cycles)and the hazardous metals–Cr,MnandNi –were found below the national ambient PM10standardand health related guidelines,respectively.
