Air pollution is made up by complex mixture exhausted from cars, industries and incinerators etc. Those pollutants come from everywhere without border and contain phototoxic and photogenotoxic chemicals including PAHs exhausted in the air. We have published that the chemicals which show phototoxicity and photogenotoxicity are closely related in mechanistic and the PAHs react as a strong photocatalyzer by radical productions under UV exposure.(omitted)

As conservation of global environment has becoming a major outstanding issue of the world, the International Maritime Organization(IMO) has been legislation a convention for prevention of air pollution from ships. By the new convention, use of air pollutants such SOx, NOx, Freon and Halin Gas shall be restricted. In this regards, analysing these requirements of the convention is required as the cinvention will also be applied in restriction of descharging exhaust gases from ships by estsblishing a requirement of Sox and NOx discharged. The purpose of this study is as follows; 1) Introdcuing of the backgrounds of legislating the convention for prevention of air pollution from ships and major contents of the convention and a countermeasuures in the convention by Korea 2) Reviewing by analyzing the influence in domestic industries concernd by restriction of SOx, NOx in exhaust gases and sulpher content of fuel oil 3) Preparing a countermeasure in the convention properly.

In this study, we try to find out the effect of private companies' environmental protection activities on the labor demand of companies in Korea manufacturing industries with empirical practice from 1992 to 2002. One of the main difficulties in this empirical work is to identify the effect of environmental protection activities on the labor demand, because the effect can be mixed with the effect of traditional production technologies on the labor demand. We follow the suggestion of Morgenstern et al. (2002) to identify the effect but which is not enough because of endogeneity between the production technology improvement and pollution reduction. So we propose a Fixed-effect Instrumental Variable estimation method as an estimation strategy. The estimation results support the positive relationship between the labor demand increase and the increase in pollution abatement costs. Therefore, we can conclude that the environmental protection activites of Korea manufacturing industries from 1992 to 2002 can help job creation without making a big burden for business activities when we consider the share of pollution abatement costs among total production costs is around 1% during that time.

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.

The temporal trends of the prioritized toxic water pollutants generated and discharged from the industrial facilities in the Geum-River basin, Korea were analyzed with the results of the nationwide Water Pollution Source Survey conducted in 2001 - 2012. The statistical results indicated rapid increase in the volume of raw toxic wastewaters whereas the amount of each toxic pollutant kept fluctuating for 12 years. Serious discrepancies in the survey data of the same type of industries demonstrated a low reliability of the survey result, which stemmed from several error factors. A unit-load for each type of industrial facility was devised to estimate the amount of prioritized toxic water pollutant based on the total volume of industrial wastewater generated from the same type of industrial facilities. The supplementary measures with an effective permit issuance policy and adding survey parameters of terminal wastewater treatment plants to use them as references to the Water Pollution Source Survey were suggested as means to minimize the errors associated with the false reports from the industries.

Recently, the deterioration of water quality in Wonju stream has been reported due to the increase in diverse pollution sources along with community development and urbanization. Various types of attempts with a huge budget were made for better water quality so far, but its effectiveness is still doubted. In order to establish site-oriented measures for water quality improvement, the topographic and hydrologic factors were evaluated based on site inspection and survey. As the major streams merged into the Wonju stream, the Hwa and Heungyang streams were found to have higher pollution loads and contributions compared to other streams due to the scattered livestock farms and industries, and vulnerable land use. Notably, the discharge water from the Wonju Public Sewage Treatment Plant had the highest level of pollution load, impacting on the water quality of Wonju Stream. According to the SWAT model as water quality measures, the improvement effect of water quality in this treatment plant can be reached to the reductions in BOD 11.06%, T-N 23.56%, T-P 10.60% when the proper managements applied, whereas the improvement of water quality would be 3.89%, 1.23%, and 3.32% for BOD, T-N, T-P, respectively, for the industries. The reduction of the livestock industry was generally very high as a pollution source, but it was not much higher at the end of Wonju Stream than other measures. These results recommended that the water q uality improvement measures should be designated for each upper-middle-lower section in Wonju stream.

As the public interest in environmental issues increased, the "Act On The Integrated Control Of Pollutant-Discharging Facility" was enacted. Through the integrated environmental pollution prevention act in which 19 industries with large environmental impacts are sequentially applied, pollutants can be managed in a medium-integrated manner and integrated permission of the business unit is possible and BAT can be applied to enable a scientific and proactive environmental management system. In addition, if the facility with BAT works normally, the pollutant emission is offered with the range of lower limit to upper limit. This study analyzed the overview of Best Available Techniques-Associated Emission Levels (BAT-AEL), and its setting procedure and method, and then suggested the BAT-AEL of a waste incineration facility. In comparative analysis on Emission Limit Values (ELVs) of EU, this study tries to propose improvement matters and development directions if the relevant standard is revised.
