Differences in risk perception on major environmental issues between general public and environmental experts were investigated in this study. Questionnaire surveys were conducted to samples from general public and environmental experts during March and April, 2000. Total number of responses was 1,126 including 773 persons from general public and 353 experts. Risk perceptions on 26 environmental issues were related with the need to regulate each issue, controllability, experience, political views, interest in environmental problem, satisfaction of environment, severity of environmental pollution. There was statistically significant difference in risk perceptions between general public and experts. Overall, general public was likely to perceive risks associated with environmental problem, as well as social need to regulate these problems more than experts. The issues with high risk perception and need to regulate were 'automobile exhaust', 'industrial air pollution', ocean pollution by industrial waste and oil exhaust', 'air pollution by chemicals', 'surface water pollution by waste from household', 'industrial and hospital waste', 'surface water pollution by pesticide'and'sewage and food waste'. Consequently, it seems necessary to manage these issues, prior to others.

It is necessary to predict future water pollution sources in the establishment of Total Maximum Daily Load (TMDL) plan for watershed management. There are some difficulties and limits in estimating the pollution sources accurately since the prediction method is not firmly established. This study reviewed the existing methods of prediction and developed a technique characteristics. The characteristics were obtained by analyzing the change pattern of pollution sources by region and incorporated in the technique. A distinctive feature of the technique is to eliminate the influences of land use change included in the pollution source data of a region. The technique has been applied and tested. The test result showed the improvement on the prediction accuracy. A computer program was also developed for the easy application of the technique.

In this study, interviews were administered to 160 children (80 boys and 80 girls) of 8 kindergartens in urban and rural areas to investigate their awareness of the effects of environmental pollution. Instruments were picture cards and a questionnaire on environmental issues, based on the revised Korean version of Cohen and Horm-Wingerd's measurement. Children's responses were classified into either awareness or non-awareness of the effect of environmental pollution. Frequencies and percentages were calculated by sub-category and tested by sex and residence, using ${\chi}^2$. Major findings were that (1) 66.0% of the children were. aware of the effects of environmental pollution. (2) 78.1% were aware of the effects of water pollution while more than half the subjects were also aware of the effects of air pollution and soil pollution. (3) Children thought that natural conditions (52.0%), human bodies (30.9%), and the daily life of people (11.7%), would be affected by environmental pollution.

Since 1962, Korea has made a remarkable progress with continuous success of Five-Year Economic Development Plans. Over the last 30 years, Korea has achieved a fast growth in various industries including heavy industry and chemical industry with rapid urbanization at the same time. The fast industrialization and urbanization brought about huge amount of hazardous/toxic substances and wastes. The environmental pollution problems have now emerged from regional concerns to overall social issues accordingly. The situation has come to a point where pollution control and environment preservation have become one of the nation's major policies. Following the recent Earth Summit of UNCED Conference held in Riode Janeiro in June 1992, where the topic was environmentally sound and sustainable development, awareness upon the importance of environmental preservation has been heightened globally, The environmental issues will gradually influence the international society more and more, politically as well as economically, The environmental pollution control industry in Korea started in the early 70's with the development of the nation's industrialization, As the people's awareness on pollution increases and environmental laws and enforcing regulations were established, demand for pollution control began to increase. The environmental pollution control business came to be recognized as an independent industry in the mid'70's. It should be evaluated properly that over the last 30 years, the Korean pollution control industry has supplied locally manufactured pollution control facilities to the increasing local demand. Concerning the quality and customer satisfaction, however, there are still many aspects which need to be improved compared with those of advanced countries. Although the start of the pollution control industry in Korea is just 10 to 15 years behind the advanced countries such as Japan and European countries, current gap in the environmental technology is rather considerable. And, studies should be made to find out the reasons for the current technology gap, and therefore, to implement solutions to improve the technology and competitiveness of the environmental pollution control industry in Korea.

Air pollution and traffic noise from roads distributed near residential area has been a major social problem. In this study, an environmental pollution map for a residential area of Shihung-city was made by an expectation model based on hourly traffic volume change. Using the result from the model, a plan to reduce population in the residential area was established. The result of the modelling is summarized as follows: 1. At peak traffic hours (18 o'clock), 301-500 degree in hazardous and $d_{25}$ degree (25% of the residents are suffering extremely from the noise) in noise pollution were predicted in Jeongwang Main Road in Shihung city. 2. The calculated critical pollutant standard index, PSI showed the air pollution level, especially PM-10 high enough to require re-entrainment. 3. It was expected air pollution would extensively extend over the area distribution of each degree. However, noise pollution problem was limited to the area near roads.

The purpose of this study was. to develop a valid and reliable Likert-type scale to assess middle school students' attitude toward environmental pollution. The evaluation categories of this instrument were cognition and conaction levels. Initially, 42 statements (29 statements for cognition level and 13 statements for conaction level) were framed. This pilot instrument was administered to 1015 middle school students. To select valid and reliable statements, the 42 initial statements were analyzed by item mean, standard deviation, and response distribution. In addition, the emotional intensity: of each statement was judged. As a result, 22 final statements (14 statements for cognition level and 8 statements for conaction level) were developed. Cronbach alpha coefficient of the instrument was 0.76 with a range of item-total correlation from 0.229 to 0.488. Factor analysis was done to explore the potential constructs of this instrument. As a result, six factors were extracted. Those factors were identified as "Conaction to prevent environmental pollution", "Confrontation with the enterprise which causes environmental pollution", "Voluntary inclination to participate in the group which prevents environmental pollution", "Discussion on environmental pollution", "Environmental pollution and interests", and "Everyday sources of environmental pollution".

This study analyzes the problems of environmental laws, development planning laws, Metropolitan Area Development Planning(MADP), and the level of environmental pollution at Pusan and Asan-Bay Metropolitan Area where MADP will be realized in the near future. In order to prevent the environmental pollution by realization of MADP, Environmental Impact Assessment Act and environmental impact assessment systems in Korea should be revised so as to reflect the followings. First, the impact of national landuse planning change on the environment should be considered at the beginning of environmental impact assessment procedures. Second, the overlapping and greater impact of many projects, whose part is the subject of environmental impact assessment, upon surrounding metropolitan area should be simultaneously evaluated and the environmental pollution protection and abatement alternatives must be made according to the above impact of the projects. Thirdly, total effluent regulation of water pollution, air pollution and solid wastes should be enforced based on the self-purification of the metropolitan area environment.

The aim of this study is to provide the basic data on misconception correction through the investigation of perception extent for 'environmental pollution' concepts in the elementary school students. For this, 18 investigation questions for concepts were created. And then a questionnaire was inputted for 446 elementary school students. The rate of average wrong answer for total questions was 34.9%. The eight questions were appeared as rate of wrong answers over average, suggesting that the misconception extent for 'environmental pollution' was still high. The extent of concepts for total questions between living environments of the study subjects did not show any significant differences. However, the urban students had significantly higher rate of wrong answers than rural students in the three questions, indicating that it is necessary to develop various teaching-learning materials on 'environmental pollution'. Therefore, the teachers have to study the various ways to induce the cognition conflicts through the application of proper teaching-learning for correction of 'environmental pollution' concepts.

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.
