  • With the rapid development of China's industrialization and urbanization, air pollution has become a growing concern. The emergence of air pollution not only affects people's health, but also restricts the development of China's social economy. This paper puts forward specific measures for air pollution control by examining the causes of air pollution and by comparing air pollution status and management policies between Korea and China. Methods of control involve improving the urban environmental management mechanism, spreading awareness of urban environmental management and air pollution management laws and regulations system, strengthening clean energy utilization and urban environmental greening, increasing investment and management funds and more. Through these measures, urban environmental management in China can be accelerated and level of environmental management improved.

  • The characteristics of non-point source pollutant loads in middle-stream of Nakdong River Were studied through analysis of pollutant loads of 8 sub-watersheds divided based on administrative district. The pollutant concentration of each sub-watershed was collected from Nakdong-River Water Research Institute and Daegu Regional Environmental Office, respectively. Pollution items analysed in this study were BOD, SS, T-N and T-P. High degree of non-point pollution was observed from Gumi, Goryeong, Gyeongsan, Daegu and Sungju, and pollution was usually increased during rainy season. This result indicates that a given pollution condition within the watershed can be more sensitive than location factor to the level of water quality. The main sources of non-point pollution were population and livestock, as well as landuse factor, and were found to significantly contribute to the water pollution. Alternative solutions for controlling pollution sources, therefore, should be provided to meet target levels of water quality in this region.

  • While overall input of oil into the sea has actually declined over the years 1975-92, major spills have regularly occurred in certain locations which have had serious effects upon local environments and hence caused public outcry. The purpose of this paper is to suggest the scheme for maximizing the compensation for oil pollution, which can be adopted in Korea, by analysing the mandatory 1969 Civil Liability Convention(CLC), the 1971 Fund Convention and two voluntary schemes (TOVALOP andCRISTAL). The paper examines the major subjects which are as follows : major pollution incidents and international response, the present situation of oil pollution in Korea, the role of flag of convenience tankers in oil pollution, the mode of oil pollution damages and tanker owner's liability, international compensation system fer oil pollution, Korean compensation system for oil pollution damage, and its problems to be tackled.

  • The main purpose of this research project is to monitor the present state of agricultural environment and to develope the countermeasures for the protection of the environment from the pollution by animal wastes. The results of this research were described largely 3 parts, 1) Monitoring of present state of environmental pollution by animal wastes, 2) Monitoring of animal wastes treatment technology, 3) Strategies for the protection of environmental pollution from animal wastes in future. The current most important problems from animal wastes are water pollution and air pollution commonly regardless of domestic or foreign country. Especially, intensive livestocks breeding pattern in restricted area is actually a real reason of eutrophication, soil acidification, ground water contamination, irrigation water pollution. As a result from this research project, authors recommend the 3 type of strategies for the protection of environmental pollution by animal wastes, 1 . Development of non-discharge type of wastes treatment technology 2. Manufacturing local structure for animal waste recycling system 3. Development of new international environmental program for transfer bioresource and soil environment prevention.

  • The application of artificial intelligence (AI) is becoming increasingly important to coping with air pollution. AI is effective in coping with it in various ways including air pollution forecasting, monitoring, and control, which is attracting a lot of attention. This attention has created high need for analyzing studies on AI and air pollution. To contribute for satisfying it, this study performed bibliometric analyses on the studies on AI and air pollution from 2012 to 2022 using the Web of Science database. This study analyzed them in various aspects such as the trend in the number of articles, the trend in the number of citations, the top 10 countries of origin, the top 10 research organizations, the top 10 research funding agencies, the top 10 journals, the top 10 articles in terms of total citations, and the distribution by languages. This study not only reports the bibliometric analysis results but also reveals the eight distinct features in the research steam in studies on AI and air pollution, identified from the bibliometric analysis results. They are expected to make a useful contribution for understanding the research stream in AI and air pollution.

  • 환경재해방지와 대기오염관리를 목적으로 GIS기반의 대기 오염관리시스템 즉 높은 시 공간적 해상도의 오염물질배출량 산정과 영향예측, 자료관리 및 분석 등이 가능한 지리정보시스템을 구성하였다. 사례연구는 다양한 오염원의 존재하여 대기오염물질 배출량 증가로 인하여 환경재해의 가능성이 상존하는 광양만지역을 선정하고, 대기오염관리시스템에 오염원의 속성 공간자료체계를 구축과 배출모형, 대기오염모델, 분석도구 등을 이용하여 배출량 산정과 영향예측, 분석 등을 수행하였다. 분석결과, 산정된 배출량이 대상지역 오염원의 위치와 오염물질의 배출특성, 공간분포와 일치하는 정확한 예측결과를 나타내었다. 또한, 대기 오염모델의 TSP 예측결과는 실측값과 상관계수가 0.75로서 다소 높은 상관도와 오염원 영향농도와 범위 등의 파악에서 명확한 분석기능이 제공되는 것으로 나타났다, 본 연구에서 개발된 대기 오염관리시스템은 신속한 공간 속성 자료체계(database)의 구축과 높은 시 공간적 해상도의 배출량 산정, 대기오염모델의 입력자료 생성, 영향예측, 다양한 결과분석 등이 가능하여 합리적인 대기오염관리의 분석도구로서 사용될 수 있을 것으로 사료된다.

  • 환경 문제에 대한 사회적 관심이 높아지고 정부의 환경 규제도 강화되면서 환경 오염물질을 줄이기 위한 공정개선의 필요성이 대두되고 있다. 공정 개선을 위해서는 각 공정이 환경에 미치는 영향을 나타내는 정량적인 기준이 필요하다. 본 연구에서는 물질수지식으로부터 정의되는 오염 지수(Pollution Index)를 폐기물의 질량(mass), BOD, toxicity에 따라 세 가지로 구분하여 정의하였으며, 각 Pollution Index는 최적의 대안을 결정할 때 환경영향평가에 대한 정량적인 척도를 제시할 수 있으므로 비용평가와 더불어 공정 선택의 객관적인 기준이 될 수 있다. 정의된 Pollution Index를 문헌에 보고된 세제 제조 공정에 적용하여 기존의 공정과 개선된 공정에 대하여 Pollution Index를 계산하여 각 공정이 환경에 미치는 영향을 정량적인 수치로 비교하였다.

  • The objective of this study is to evaluate a criteria of intercepting capacity and a reduction goal of overflow pollution load in combined sewer system. In the current criteria of intercepting capacity in the domestic sewage facility standard, it is known that three times of peak sewage (Q) in dry period or runoff flow by 2mm/hr is not appropriate since the intercepted flow is estimated by runoff and show different result even in the same watershed. Though a reduction goal of overflow pollution load can be determined from 1) same level of storm-water runoff pollution load in separated storm sewer, 2) less than 5% sewage load in dry weather period, by the domestic sewage facility standard, the simulated results from storm-water model show large differences between two criteria. While it is predicted that sewage pollution load standard three time larger than separated storm sewer standard in high population density and urbanized area, it is shown that separate storm sewer standard larger than sewage pollution load standard in middle population density and developing area. Accordingly, it is proposed that more reasonable intercepting flow and reduction goal of overflows pollution load should be established to minimize discharging pollution load in combined sewer systems. For the purpose, a resonable standard has to be amended by pollution load balance considering the characteristics of a watershed for generation, collection, treatment, and discharging flow.

  • 최근 수확불변 하에서의 오염처리비용회피활동(pollution haven activities)에 대한 연구는 많이 진행되어 왔으나 수확체증 하에서의 연구는 미미한 실정이다. 1990년대 이후 수확체증 하에서의 교역이론이 산업 재배치에 대한 문제를 다루면서 수확체증과 오염처리비용회피활동 간의 관계를 살피는 것은 의미 있는 일이다. Davis (1998)가 발표한 수확체증 하에서의 자국시장효과(home market effect)에 대한 모형을 응용하여 환경정책이 산업 재배치에 주는 효과를 분석한 결과 시장규모가 적은 지역에서 오염물처리에 대한 책임을 생산자가 담당하는 지역과 시장규모가 크면서 오염물로 인한 비효용을 거주자가 감내하는 지역과의 교역상황에서 교역장벽이 높을 때 일부 공해산업에 대해 오염처리비용회피효과가 존재하나 교역장벽이 낮아지면서 공해산업뿐만 아니라 저공해산업에서도 산업의 지역이탈이 관찰되어 오염처리비용회피활동에 대한 식별이 힘들어지며 오염처리비용회피효과(pollution haven effect)뿐만 아니라 오염처리비용회피가설(pollution haven hypothesis)이 동시에 성립됨을 보일 수 있었다. 따라서 시장규모가 작으나 환경보전가치가 높아 환경규제가 강한 지역에서 환경보전과 지역경제발전을 동시에 도모하기 위해서는 오염처리기술의 생산성을 높이기 위한 활동이 필수적이다.
