In Korea, odor emission control is carried out at the boundary between the discharge port and the site based on the height of the discharge port, but in Japan and the U.K. a range of characteristics are considered in odor management, including the height, size, and amount of exhaust gas, when managing the acceptance criteria of the discharge port that conforms to the odor concentration standards based on the site boundary. In this study, the permitted concentration of odor in the outlet was studied considering the design conditions of the outlet, in order to manage it based on the distance between the outlet and the residential area. To improve the effectiveness of odor management, Korean odor management measures were reviewed by applying the methods used to calculate odor concentration in Japan and the U.K. Guidelines on effective odor reduction were provided by calculating the permissible odor concentration for each condition based on the flow rate and height of the final outlet to comply with the permissible concentration at regular intervals at the outlet of the factory.

This paper presents the results of a human health effect for H2S emission standard of incinerators in Seoul, Korea. The four selected incinerators of Gangnam, Mapo, Nowon and Yangcheon were chosen as the domains of study. Air dispersion modelling (AERMOD) was used to predict the ground level concentration within 3 km distance of the emission source. The emissions at the incinerators studied ranged from 0.0721 (Yangcheon) to 0.3007 g/s (Gangnam). These values were about three orders of magnitude smaller than that of Canadian geothermal power plants. Based on the health risk assessment, different health risks were identified for short-term and long-term dispersion of the studied areas. The short-term hazard quotient (HQ) for H2S of Gangnam and Nowon incinerators were greater than the acceptable limit (i.e., 1.0) in some locations. However the long-term HQ for H2S of all incinerators were lower than the acceptable limit.

Establishment of emission standard of dioxins from crematories has been needed for their efficient management in korea. In this study, we investigate related regulation, guideline and management of crematory at home and abroad. Either dioxin legal basis or management of countries are compared and analyzed respectively. Crematories were distributed 51 place all over the country and total 265 crematories have been operated in 2000. Korea crematories have been operated 3 steps; incineration, cooling in furnace and collection of bone. This process is similar with Japanese process. But European process is different steps; incineration, keeping the temperature of furnace and collection of bone. In case of Korea, the resynthesis of dioxins in the cooling process due to the dioxin emissions higher than European process. This study has suggested three emission standards of dioxins from crematories based on survey of foreign standards and korean measurement data. The 1st suggested standard is 10 ng-TEQ/Sm3 in present facility, 5 ng-TEQ/Sm3 in new facility, the 2nd suggestion is 5 ng-TEQ/Sm3 in present facility, 1 ng-TEQ/Sm3 in new facility and the 3nd suggestion is 0.5 ng-TEQ/Sm3 in present facility, 0.1 ng-TEQ/Sm3 in new facility. When 2nd suggestion apply, at 2020 dioxin emissions(0.779 g-TEQ/yr) is expected to be approximately 71% reduction compared to 2010 year.
