摘要	The objective of this project was to develop the sampling and analytical methods for hazardous air pollutants, including bromoform, 1,1,2-trichloroethane, 1,4- dichlorobenzene, benzyl chloride, 1,2-dibromoethane, 1,4-dioxane, and 1,1,2,2- tetrachloroethane in flue pipe, and bromoform in ambient air. The sampling and analytical methods of 1,1,2-trichloroethane, 1,4-dichlorobenzene, benzyl chloride, 1,2- dibromoethane, and 1,4-dioxane, which were studied in EPA’s project in 2018, and the Method NIEA A721, which was published for 1,1,2,2-tetrachloroethane in flue pipe by Environmental Analysis Laboratory, were optimized in this study Based on the experiments, the storage results in 24 hours of six target compounds (bromoform, 1,1,2-trichloroethane, 1,4-dichlorobenzene, benzyl chloride, 1,2- dibromoethane, and 1,1,2,2-tetrachloroethane) in Tedlar sampling bags, which has better storage performance than others, were not acceptable, which indicated that the sampling method using Tedlar bags for this six compounds in flue pipe was not suitable. Afterwards, the sampling method using absorption solvent (hexane) with constant flow was evaluated. Based on the test results, the capture capacities, storages, and method detection limits were all qualified for the detection requirements of the emission standards of flue pipe. As for 1,4-dioxane, due to its solubility (miscible with water), the sampling method for flue pipe was absorption solvent (methanol) with isokinetic sampling. When three impingers were connected in series, the capture capacity was acceptable, the method detection limit was 0.035 ppmv, and the method was qualified for the detection requirement of the emission standard of flue pipe. As for bromoform in ambient air, the canister method was evaluated. The storage results in 14 days was acceptable, and the method detection limit was 0.039 ppbv. The sampling and analytical methods developed in this project were proven to be practical by surveying at least 4 field samplings (flue pipe or ambient air). Besides, two technical communication seminars were taken place in September and October. All the study results were reported in the technical drafts for EPA’s reference.
