| Abstract | Dioxin is a common term used for a group of toxic chemical compounds which are highlypersistentin the environment. It is formed as an unintentional by-product of many industrial processes involving chlorine, and it is one of the most dangerous compound that effect human health, wildlife and environment. In this study, emission inventory of the polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzo furans (PCDFs) from the potential point sources in Thailand was developed by using theactivity data during 2015-2017, and thirteen point sources were included. Dioxin released to the air, water and residues were included in this study. The 2015 UNEP toolkit for dioxin emission inventory development was used to estimate dioxin emission from six point source categories in Thailand, including waste incineration, metal production, power plants, mineral productions, useof chemical andconsumer goods, and crematoria. For emission factors, the emission factors developed in Thailand were used instead of the emission factors provided by the toolkit, except for the sources that have no measurement in Thailand. The results show that the total amounts of PCDDs/PCDFs emission in 2017 were 95.15 g-TEQ to the air, 282.14 g-TEQ in the residues, and 2.56 g-TEQ to the water. The three major emission sources of dioxin to the air were crematories, biomass power plants, and iron and steel plants which emitted 45.10 g-TEQ (47.4%), 16.63 g-TEQ (17.48%), and 15.10 g-TEQ (15.87%), respectively. The highest amounts of dioxin (2.56 g-TEQ) discharged to the water were from the pulp and paper and EDC/VCM/PVC industries. Significant sources of dioxin released in the residues were from the municipal solid waste incineration (119.63 g-TEQ or 42.4%), iron and steel plants (75.51 g-TEQ or 26.76%), medical waste incineration (43.65 g-TEQ or 15.47%), crematories (19.17 g-TEQ or 6.79%), and biomass powerplant (11.87 g-TEQ or 4.2%). |
