  • Environmental pollution is common problem of the present world that is intimately related to the future survival of human beings. The problems of environmental pollution originate from the pursuit of benefit by enterprises, insufficient countermeasure of government and ignorant life style of the people. Health hazards due to environmental pollution have characteristics of irreversibility, difficulty in measurement and ineffectiveness of personal prevention. Objects of this article are to review the various aspects of environmental pollution, to outline the present status of environmental pollution and strategy to control environmental pollution in Korea. In the first part of this article, causes of environmental pollution are presented. International relationships, world-wide status of environmental pollution and health hazards due to environmental pollution are briefly reviewed. In the second part, present status of air, water, soil and ocean pollution in Korea is presented. Pollution by radioactive materials, noise, vibrations, odor, wastes and chemicals is reviewed.

  • To investigate the risk perception of environmental issues, two consequtive surveys were conducted to environmental professionals using a standardized questionnaire from September to October in 1999. The number of subjects were 72 for the first survey and 68 for the second one. The questionnaire was consisted of items such as the degree of environmental pollution in Korea, risk perception of some issues on human health and ecosystem, and seriousness of the problems in the real situation in Korea. For the degree of environmental pollution in Korea, the average risk rating in the second test (7.4 point) was significantly higher than that in the first test (7.2 point). The risk perception on the general human health and ecosystem, and the seriousness in Korea situation were analyzed in the order of ′air pollution′, ′water pollution′,′soil contamination′,′waste′,′toxic chemical pollutants′,′food contamination′,′ocean contamination′, ′odor pollution′, and ′noise pollution′. Also ′toxic chemical pollutants′ problem was perceived to be the highest risk on general human health or ecosystem, and on present situation in Korea. ′Automotive vehicle exhaust′ problem was perceived to be the most severe environmental problems among specific 30 items. ′Industrial source air pollution′,′toxic air pollutants′, and ′domestic and industrial source pollutants to surface water′ were relatively severe environmental problems comparing to other problems. The pollution issues were classified into four categories by two aspects of perception; risk in general setting and seriousness in Korea situation. If the issues were highly serious in Korea and low risk perception in general setting then it is named "the Korea-specific group". Those that were all high score in two aspects, named "the Common group". Those that were all low in two aspects, named "the Nonsignificant group". And the issues were high risk perception in general setting and low seriousness in Korean situation, named "the Latent group".

  • As a result of accepting the '71 FUND Convention and enforcing the Oil Pollution Compensation Act 1992, we observed some benefits and costa. This paper analyses those benefits and costs and suggests se-veral key policy recommendations for the estasblishment of an effective oil pollution compensation regime in Korea. This paper identifies the said benefits and costs as follows : First, by establishing the oil pollu-tion compensation system as same as the international level, most of small and medium size of oil pollution damage which are caused by coastal tankers will be compensated by FUND. Second, most of oil pollution damage which are not covered by '69 CLC will be compensated by FUND. Third, some parts of FUND Contribution Fee and CRISTAL Contribution Fee to be charged by major oil companies will be doubled. However the limit of international oil pollution compensation system and the loophole outside the Oil Pol-lution Compensation Act 1992 suggest followings : 1) Radical risk management and insurance manage-ment of ocean going tanker owners, 2) Establishment of oil pollution claim settlement system, 3) Enforce-ment of crew and ship management for coastal tanker and 4) Establishment of Korean P & I Club.

  • We try to distribute air pollution sources at target area. The complex method is used to distribute air pollution sources. Most of people, However, want to simple indicator as standard for express air pollution source. In many area, air pollution is caused by different types of sources. The general type is point source, such as tall stack of power plants and oil refineries stacks. A second type is areal source, such as local industry and transportation. In this aspect, the ratio of sulfur dioxide to nitrogen oxides (RSN =SO$_2$/NOx)is an indicator of air pollution source. the role of this ratio is to show the characteristics at target area of the relationship the point and the areal source.

  • The factor of air pollution in a large industrial city is not only manufactories but also, activities related to trucks. Sihwa National Industrial Complex is located in Siheung City; due to the industries, more diverse activities related to trucks occur in Siheung City than other cities. In particular, the new residential area in Siheung City is close to the industrial complex; so, the damage of this residential area is expected that it would be more serious and vulnerable than other areas. The aim of this study is to analyze influence of the air pollution by a truck in Siheung City. ISCST3 Model and Arc View program were used for this study and Siheung City was divided into 1,000 meter by 1,000 meter grid to analyze. Furthermore, this study suggested two reduction controls of air pollution in Siheung City, and analyzed the results from these reduction managements. The results of the present condition showed that residences located in north of Sihwa Industrial Complex are influenced by air pollution material. Furthermore, air pollution by trucks has affected on the residents which is near the road in Siheung City. Therefore, this study suggested two reduction controls by the Traffic System Management. The first alternative plan is setting the truck traffic limitation zone in the road that is located in south of resident areas and many trucks traffic. Next, the second alternative plan is setting freight truck way on the most traffic road to enter the industrial complex. The reduction effect of the first alternative is good on the residential area. And, the second alternate about freight truck way is divided passenger cars into trucks. Therefore, there are increase of average speed and decrease of average concentration, and spatial reduction effects found in wide areas.

  • 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 purpose of this study is to evaluate representativeness of fuel-based emission factors. Twelve light-duty diesel vehicles which meet Euro-3 to 5 legislative emission limits were selected for emission tests. Second-by-second modal emission rates of vehicles were measured on a standard laboratory chassis dynamometer system. An off-cycle driving cycle was developed as a representative Korean real-world on-road driving cycle. Fuel-based emission factors were developed for short trip segments that involved in the selected driving cycle. Each segment was defined to have unit travel distance, which is 1 km, and characterized by its average speed and Relative Positive Acceleration (RPA). Fuel-based $NO_x$ emission factors demonstrate relatively good representativeness in terms of vehicle operation conditions. $NO_x$ emission factors are estimated to be within ${\pm}20%$ of area-wide emission factor under more than 40% of total driving situations. This result implies that the fuel-based $NO_x$ emission factor could be practically implemented into the on-road emission management strategies, such as a remote sensing device (RSD). High emitting vehicles as well as high emitting operating conditions heavily affect on the mean values and distributions of CO and THC emission factors. Few high emitting conditions are pulling up the mean value and biasing the distributions, which weaken representativeness of fuel-based CO and THC emission factors.
