  • 현재 환경영향평가가 이루어지고 있는 전체사업 가운데 도로사업을 통한 환경영향평가의 비율은 60%이상으로 다른 영향평가에 비해 상당한 부분이며, 또한 대기 중에 배출되는 총 오염물질 중에서 도로상의 차량에서 배출되는 오염물질이 최대로 70%까지 차지한다. 위와 같이 도로상에서 배출되는 오염물질의 영향을 파악하기위해서는 도로 주변에서의 현지측정을 통한 정량적 평가가 필요하나 이를 위해서는 많은 시간과 비용이 소요되어 현실적으로 불가능하다. 그러므로 이에 대한 대안으로 대기확산모델을 이용하여 도로상의 오염물질의 영향을 예측한다.

  • The important changes in water environment management in Korea can be summarized as the enactment of Act on the Integrated Control of Pollutant-Discharging Facilities. Therefore water quality impact assessment should be reexamined and be revised. This study examines the present water quality impact assessment items (permissible discharge limits, standards for effluent water quality including Total Pollutant Load Management System) and considers the land use regulation for water quality conservation and NVZs(Nitrate Vulnerable Zones of EU and England). It also considers lately adopted standards(maximum discharge standards, permissible discharge standards, and marginal discharge standards etc) based on Act on the Integrated Control of Pollutant-Discharging Facilities and then compares Korean BAT and its counterpart control technology of U.S.A. And it also compares the items of water quality impact assessment with those of Integrated Control of Pollutant-Discharging Facilities, based on EIS reporting items. This study suggests five improvement measures for water quality impact assessment. First reflection of discharge impact analysis on impact prediction and assessment, second reflection of permissible discharge standards on agreed standards in the EIA procedure, third, reflection of diversified BAT on mitigation measures in the EIA procedure, forth introduction of land use regulation such as NVZs, finally strengthening linkage between water quality items and land use items etc.

  • In this work, soil environment policy which should be taken into account at brownfield redevelopment projects was deduced from investigation on their environmental impact assessment statements. Soil contamination sources such as small-scale factories were found at a few large-scale brownfield projects, so contaminated soils did often exist at these sites. Especially, military facilities within the sites caused severe soil contamination problems. Therefore, soil environment policy was presented in detail to solve soil contamination problem at brownfield redevelopment projects. Furthermore, land-use planning focusing on greening (soil and vegetation) should be pursued at brownfield redevelopment projects in order to maximize environmental benefits of greenspace.

  • There are generally two types of groundwater vulnerability assessments. Intrinsic vulnerability is based on the assessment of natural climatic, geological and hydrogeological attributes and specific vulnerability relates to a specific contaminant, contaminant class, or human activity. Several methods to assess groundwater vulnerability, which are based on hydrogeologic setting and socio-economical environment, have been developed in USA and Europe. A Modified-DRASTIC model including a lineament factor has been developed in South Korea, but it still has some limitations. To develop a solid and applicable method in this country, many data of quality, hydraulic features, GIS data, and pollution source, produced from a Basic Survey based on Article 5 of the Groundwater Act and other research projects, need to be collected, analyzed and verified introducing the previous methods.

  • Chemical analyses are generally used to assess contaminated soils and to monitor the efficiency of soil remediation. In this study, the ecotoxicological methods was suggested to evaluate soil pollution by using a battery of bioassay. Plant assay and earthworm assay were conducted to evaluate ecotoxicity o soils contaminated by heavy metals (cadmium and copper) and oil (BTEX compounds, toluene). Test plants were Zea may, Triticum aestivum, Cucumis sativus, and Sorghum bicolor. The presence of heavy metals decreased the seedling growth. Cucumis sativus and Sorghum bicolor seemed to be good indicator plants which are sensitive to heavy metal pollution as well as BTEX contamination. An earthworm bioassay was performed to predict the ecotoxicity in toluene-contaminated soils, based on a simple contact method. Perionyx excavatus was adopted as a test earthworm species, and the severity of response increased with increasing toluene concentration. The present study demonstrated that ecotoxicological methods could be a quantitative approach to evaluate contaminated soils.

  • 경제성장과 더불어 환경에 대한 일반인들의 관심이 증가되어 기존의 환경기준 대상 오염물질 위주의 대기질 평가 외에 소음이나 악취 등의 감각공해에 대한 체계적인 연구가 필요하게 되었다. 악취에 의한 오염은 인간이 오감을 통해서 느끼는 정신적 피해의 하나로 청각을 통한 소음문제, 미각을 통한 음용수문제, 시각을 통한 경관의 문제 등과 같은 감각공해 중 대표적인 오염현상으로 생활환경의 쾌적성과 밀접한 관계를 갖고 있다. (중략)

  • 오염부지 관리 기조가 매체 중심에서 수용체 중심으로 변화하면서 우리나라에 위해성평가 제도가 도입되었으나, 이를 오염현장에 충분히 활용하기 위한 체계와 관련 기술들은 아직 제대로 확립되어 있지 않다. 특히, 여러 가지 이유로 정화곤란부지로 분류가 되는 오염부지의 정화 및 관리와 그러한 부지에 적용될 수 있는 위해저감기술들에 대한 기술적, 사회적 논의와 합의도 부족한 실정이다. 본 연구에서는 그동안 오염토양의 정화에만 초점이 맞추어진 우리나라의 토양환경정책이 오염부지의 관점에서 그와 연결된 수용체를 보호하는 방향으로 나아가기 위해 필요한 위해성기반 오염 부지관리 의사결정체계를 제안하고, 그러한 관리체계가 현장에서 적절히 적용되도록 하기 위해 필요한 위해저감기술들을 조사, 분류하여 위해저감 방식에 따른 위해저감기술의 활용성 및 적용성을 평가하는 방안을 제안하였다.
