  • When evaluating the extent of the impact of water pollutants on the surrounding area, we would like to present the target level (proposal) of the quality of the environment, which is the standard for evaluation. We propose the environmental quality target level for substances that need to be applied domestically by investigating overseas cases operating the integrated environmental management system and the implications of domestic environmental pollutant management. The appropriateness of the environmental quality target level reviewed in this study was determined using data from the water quality measuring network, and future improvement measures were proposed. We review the available methodologies for setting quality objectives for the environment. It proposed the environmental quality target level for 21 substances that have domestic water pollutant emission standards and do not have environmental standards, and proposed future improvement measures. If it is necessary to add quality target-level items of the environment in the future, it is believed that expansion will be possible based on the methodology presented in this study.

  • 본 연구에서는 최근 신종플루가 유행하여 수용성이 큰 항바이러스제인 타미플루(Oseltamivir ethylester phosphate, OEP)가 다량 사용됨에 따라 환경 중 잔류농도를 파악하고, 수생태 영향을 평가하고자 하천수를 채취하여 분석하였다. 타미플루의 주성분인 오설태미비르 에틸에스터(Oseltamivir ethylester, OE) 및 활성대사체 오설태미비르산(Oseltamivir carboxylate, OA)이 모든 지점에서 각각 $0.008\sim0.087\;{\mu}g/L$, $0.029\sim0.287\;{\mu}g/L$의 범위로 검출되었으며, OE보다 활성대사체(OA)가 상대적으로 높게 검출되었다. 이는 신종플루 대유행 이전인 일본 수질조사 결과에 비해 OA는 2배 높게 나타났으나, 시료채취 시기가 달라 직접적인 비교는 어려운 것으로 판단되었다.

  • Objectives: This study was conducted to assess environmental health status on a local scale using environmental health-related indicators. It demonstrated the possibility of using a structural equation model, a methodological approach to provide synthesized information. Methods: Eighteen indicators were selected from official statistical data published by local governments. Each environmental health-related indicator was classified according to the PSR (pressure-state-response) model. Aggregation methods were performed using principal component analysis and fuzzy sets. Results: The five principal components were classified through principal component analysis (PCA) and obtained eigenvalues >1.0 from the initial 18 indicators. The aggregated index was obtained by condensing the original information into two broad and simple categories through fuzzy sets. Conclusion: This could be useful in that the aggregation procedure may provide a basis for establishing environmental health policies and a decision-making process. However, the availability and quality of indicators, assessment of aggregation method bias, choice of weighted scores for indicators, and other factors should be examined in future studies.

  • K leather industry wastewater treatment plant(advanced treatment process) was selected to evaluate effluent quality and pollutants removal efficiencies. $BOD_5$ concentration of effluent was $3.95mg/{\ell}$ and its removal efficiency was 99.8%. Also, most of other pollutants removal efficiencies were over 90% as well. And 95% reliability of effluent concentration were $106.8mg/{\ell}$ of CODmn, $86mg/{\ell}$ of SS, $72.04mg/{\ell}$ of TN that is greater than the effluent limitation, $0.98mg/{\ell}$ of ABS, $1.8mg/{\ell}$ of n-Hexane, $9.7mg/{\ell}$ of $BOD_5$ and $0.11mg/{\ell}$ of Cr.

  • BACKGROUND: Water quality is of concern to water utility operators, public health officials, and populations using the water. If any contaminant is released from a point of entry, it could be spread rapidly throughout the water stream. So the identification of the location of the points of entry and its release history are critical informations to establish the management strategy.METHODS AND RESULTS: Aniline, nonylphenol, pentachlorophenol and formaldehyde in 39 surface water samples were analysed using Gas chromatography-mass spectrometry (GC-MS) methods. Formaldehyde, aniline and nonylphenol were mainly detected in the near sites where industrial waste water and domestic sewage were discharged into stream. But pentachlorophenol was detected in the downstream samples where pulp manufacturing plants were operated.CONCLUSION: Results indicate that pentachlorophenol found in main stream of Guem river was mainly introduced from pulp manufacture industries. Otherwise, formaldehyde, aniline and nonylphenol were mainly contaminated from the industrial waste water and domestic sewage.
