  • 연안개발에 따른 유기물 오염은 유기물 오염지표종의 분포를 증가시키고, 증가된 유기물 오염지표종이 대상해역에 장기간 우점하여 저서생태계를 교란시킨다. 하지만 아직까지 우리나라 전 해역을 대상으로 조하대 저서생태계 유기물 오염정도를 확인한 연구가 미미한 실정이다. 이에 본 연구는 연안개발 환경영향평가 대상사업의 조하대 저서동물 조사결과를 분석하여 유기물 오염지표종의 분포를 확인하고, 우리나라 전 해역 조하대 유기물 오염정도를 간접적으로 확인하였다. 유기물 오염지표종별 분포 현황을 이미지 프로그램을 통해 지도로 작성하고, 전체 출현분포 현황을 통해 전 연안의 저서건강도지수(BHI, Benthic Health Index)를 도식화하였다. 유기물 오염정도는 사업구분 및 유기물 오염지표종별 분포가 다양하였으며, 유기물 오염지표종 중 Lumbrineris sp.가 전 해역에 가장 우점한 것으로 확인되었고, 전체 조하대 유기물 오염정도와 상관관계가 있는 것으로 확인되었다. 앞으로의 조하대 저서생태계 유기물 오염정도는 유기물 오염지표종 분포를 통해 확인하고, 향후 연안개발 계획 수립 시 참고자료로 활용할 수 있을 것으로 기대한다. 또한, 유기물 오염지표종 중 Lumbrineris sp.의 분포는 간접적으로 개발 대상지의 유기물 오염정도를 평가할 수 있는 지표로 사용 가능할 것으로 판단된다.

  • Korea has experienced dramatic development and has become highly industrialized and urbanized during the past 40 years, which has resulted in rapid economic growth. Due to the industrialization and urbanization, however, air pollutant emission sources have increased substantially. Rapid increases in emission sources have caused Korea to suffer from serious air pollution. An air pollutant emissions inventory is one set of essential data to help policymakers understand the current status of air pollution levels, to establish air pollution control policies and to analyze the impacts of implementation of policies, as well as for air quality studies. To accurately and realistically estimate administrative district level air pollutant emissions of Korea, we developed a Korean Emissions Inventory System named the Clean Air Policy Support System (CAPSS). In CAPSS, emissions sources are classified into four levels. Emission factors for each classification category are collected from various domestic and international research reports, and the CAPSS utilizes various national, regional and local level statistical data, compiled by approximately 150 Korean organizations. In this paper, we introduced for the first time, a Korean national emissions inventory system and release Korea's official 2007 air pollutant emissions for five regulated air pollutants.

  • This research is based on self-filling survey which 656 dental hygienists who work in, seoul, the metropolitan area, jeon-buk area participated on July 2006 through August 2006. This survey was analyzed the relationship between the subjective symptoms(6 types) and outdoor air quality($O_3,\;NO_2,\;CO,\;SO_2,\;PM_{10}$) As follows analyzed results. The health condition of dental hygienists were "Feel Good" more than 50% in last month. The experience the symptoms level is higher then non-experience level in "Dry eye, itch, smarting", "Headaches", "Fatigue and sleepiness", "Red eye", "Hypersensitivity", "Dorsalgia, omarthralgia, cervicodynia". We anticipated that the more experience the subjective symptom the more likely it is that outdoor air quality will be high rate level. But we could not find the uniformity in metropolitan-area and seoul-area. In the case of jeonbuk area, the group's pollution density levels which experienced the subjective symptom were appeared high rate than inexperienced group except $SO_2$. It probably comes from sensibility for an air pollution in this area. Dental hygienists who work in jeonbuk area have an unusual sensibility for an air pollution because outdoor air quality of jeonbuk area was rule good rather than others area. especially $SO_2$ was revealed out even though low rate level in inexperienced group it is that the number of cars in jeonbuk area is increasing rapidly.

  • Air pollution in urban areas of Korea is considered in significantly serious level because of population exceeding the capacity and diversified facilities for the activities in socioeconomic field, education, politics and even cultural society in confined areas. Korea is one of the most populated countries and the largest five cities occupy 2.4% of total area but 45% of total population. Patterns of urban air pollution are also changing due to the change of emission sources and fuel usage. Essential recovery of urban environment in Korea has become extremely difficult and necessitates enormous investment. Accurate understanding of problems should be pursued for the efficient and effective improvement of the environment. In this article, air pollution phenomena in urban areas are analyzed mainly with respect to recent urban air pollution trend and pollution sources and possible control strategies are discussed : 1) source control-stationary and mobile, 2) air quality management strategies, 3) research and development.

  • Variations in species diversity and abundance of polychaete taxocenes that occurred in 1980-1989 under different contamination levels of bottom sediments were studied in three areas of Peter the Great Bay. The most polluted area was shown to be the Golden Horn Inlet where contaminant contents in the bottom sediments exceed the threshold values of negative biota alterations. Amursky Bay is characterized by a moderate level of contamination, while Ussuriysky Bay has the lowest level of contamination. Pollutant contents vary considerably within the same areas and their separate patches are polluted differently. An integral index characterizing the contamination of bottom sediments is proposed. This index is an average grade of the rank value of contaminant contents in sediments. The index was used to compare the contamination level and data on polychaete species diversity and abundance. The highest species diversity of polychaetes is found in the least affected zones. Monotonous decrease of the species number, as well as decrease in the indices of diversity and evenness, is correlated with pollution level increases. Significant growth of the average polychaete biomass and polychaete density is observed in the case of an increase of contamination from low to moderate levels. Conversely, the biomass and abundance of polychaetes decline following an increase in contamination.

  • Public awareness of air pollution problem has increased the need for real time air pollution information system about changes in air pollution level. The purpose of this study is to construct e-AIR, a user-friendly air pollution information system for urban air quality using GIS(geographic information system) technology for windows. GIS was ideally suited featuring a geographical characteristics(e.g., road, traffics, buildings) and very effectively used in mapping and symbolization for the distribution of the spatial/periodic pollution status(e.g., pie or column chart, graduated symbols) which can be effectively applied to a information system on the web-site. And a user interface, GUI(graphic user interface) was designed very diversely and simply enabled the users connect with e-AIR and obtain a useful information of air quality. A interpretive technique, air pollution health index(e.g., PSI, AEI) was used also which transforms complex data on measured atmospheric pollutant concentrations into a single number or set of numbers in order to make the data more understandable. Eventually the final-step of this study was to construct e-AIR based on Web GIS could be assessed anywhere if internet is available and offer a very useful information services of the air pollution to the public like a weather news.
