Because of the rapid progress of urbanization in recent decades, the proportion of impervious areas in cities has increased. As a result, hydrological properties of urban streams have changed and non-point pollution sources have increased, that have had considerable influence on human life and ecosystems. To manage these situations, application of non-point pollution reduction facilities and LID facilities are expanding recently. In this study, it is investigated if rainfall interception rate used in design of non-point pollution reduction facilities can be applied to design of LID facilities. For this purpose, EPA SWMM is constructed for part of Noksan National Industrial Complex area wherein long-term observed storm water data can be obtained and storm water interception rates for various design capacities of a bio-retention LID facility reservoirs are estimated. While sensitivity of storm water interception rate according to design specifications of bio-retention facility is not large, sensitivity of storm water interception rate according to regional rainfall characteristics is relatively large. As a result of comparing present rainfall interception rate estimation method with the one proposed in this study, the present method is highly likely to overestimate performance of the bio-retention facility. Finally, a new storm water interception rate formula for bio-retention LID facility is proposed.

폐기물처리시설의 지속적인 설치·정기검사에도 불구하고 현장 처리시설에서는 과다소각, 불법투기 악취 등에 대한 민원이 지속적으로 발생하는 것으로 보아 현재의 폐기물처리시설 설치정기 검사방법의 개선이 필요하다고 판단되었다 이에 현재 운영중인 폐기물처리시설(6개분야)을 대상으로 현장조사를 실시하여 각 분야별 폐기물처리공정을 파악하고 검사에 적용된 주요한 운영인자를 파악하고, 주요공정별 물질·에너지수지를 산정하여 폐기물처리시설의 적정 운영 여부를 확인하였다. 주요 운영인자 조사 결과 소각 및 시멘트 소성로, 소각열회수시설 등의 경우 소각에 필요한 소각로의 온도 유지 및 발생되는 대기오염물질의 처리가 가장 주요한 인자였으며, 매립시설의 경우 옹벽의 안정성, 매립 후 발생되는 침출수 및 배출가스 관리가 주요한 인자로 나타났다. 멸균·분쇄시설의 경우 멸균여부(아포균검사)가 가장 중요한 주요인자 이었으며, 음식물류폐기물처리시설의 경우 발효(소화, 부숙) 시 체류시간 및 악취관리가 주요한 인자로 나타났다. 또한 물질에너지수지 산정 결과 소각시설의 경우 폐기물 투입량 대비 바닥재 발생량은 약 14%, 비산재 발생량은 약 3%로 적정 운영되고 있을을 확인하였다. 또한 음식물류폐기물시설 중 혐기성분해시설의 경우 유입량 대비 바이오가스 발생량은 약 17%, 바이오가스 전환효율은 약 81%로 나타났고, 퇴비화시설의 경우 유입폐기물 대비 약 11%의 퇴비가 생산되어 모두 적정운영 되고있음을 확인하였다. 이에 따라 폐기물처리시설 검사방법의 고도화를 이루기 위해 세부검사방법의 정량적 기준 적립 뿐만 아니라 각 시설의 정기검사 시 1년간의 운영자료 등을 수집하여 폐기물의 흐름을 파악하고 처리시설의 적정운영 여부를 판단한다면, 처리시설의 운영 및 관리효율이 상승할 것으로 판단된다.

In the study, pollution levels of indoor polycyclic aromatic hydrocarbons (PAHs) in public facilities (vapor phase or particulate phase) were evaluated, and a health risk assessment (HRA) was carried out based on exposure scenarios. Public facilities in Korea covered by the law, including underground subway stations, funeral halls, child care facilities, internet cafes (PC-rooms), and exhibition facilities (6 locations for each type of facility, for a total of 48 locations), were investigated for indoor assessment. For the HRA, individual excess cancer risk (ECR) was estimated by applying main toxic equivalency factor (TEF) values suggested in previous studies. Among the eight public facilities, internet cafes showed the highest average $PM_{2.5}$ concentration at $110.0{\mu}g/m^3$ (range: $83.5-138.5{\mu}g/m^3$). When assuming a risk of facility exposure time based upon the results of the surveys for each public facility, the excess cancer risk using the benzo(a)pyrene indicator assessment method was estimated to be $10^{-7}-10^{-6}$ levels for each facility. Based on the risk associated with various TEF values, the excess cancer risk based upon the seven types cancer EPA (1993) and Malcolm & Dobson's (1994) assessment method was estimated to be $10^{-7}-10^{-5}$ for each facility. The excess cancer risk estimated from the TEF EPA (2010) assessment was the highest: $10^{-7}-10^{-4}$ for each facility. This is due to the 10-fold difference between the TEF of dibenzo(a,e)fluoranthene in 2010 and in 1994. The internet cafes where smoking was the clear pollutant showed the highest risk level of $10^{-4}$, which exceeded the World Health Organization's recommended risk of $1{\times}10^{-6}$. All facilities, with the exception of internet cafes, showed a $10^{-6}$ risk level. However, when the TEFs values of the US EPA (2010) were applied, the risk of most facilities in this study exceeded $1{\times}10^{-6}$.
