The major objective of this study is to evaluate two different sampling techniques used for collecting atmospheric samples of 17 target organic compounds. These target organic compounds include methyl acetone, methyl butyl ketone, methyl isobutyl ketone, acetone, methyl ethyl ketone (2-butanone), methyl methacrylate (MMA), ethyl acetate, methyl acetoacetate, methyl acrylate, methyl butyrate, methyl amyl acetate, methanol, ethanol, ethylene glycol, glycerin, isopropyl alcohol and n-butyl alcohol. Two types of commonly used sampling media, SUMMA canister and sorbent trap have been tested for their collection efficiencies. The test will include sample recovery, medium breakthrough (sorbent trap), method detection limit, analytical precision, and accuracy. The samples will be analyzed by gas chromatography/mass spectrometry (GC/MSD). Furthermore, this study has investigated the existing levels of these 17 target organics in the proximity of four major petrochemical industrial parks. Thirty atmospheric samples have been collected from these four industrial parks. The results will be used as a reference for government to establish regulatory emission limits for these 17 target organics.
