In this study, we looked into the levels and distribution characteristics of harmful substances found in imported coal ash to identify their possible impacts on the environment and human body in the process of recycling and to develop plans for their proper management. To this end, organic pollutants including heavy metals were analyzed from 19 samples of imported coal ash, and their potential impact on the environment was evaluated. To investigate the characteristics of the heavy metal content in the coal ash, a leaching test was conducted, and the result showed that the heavy metal concentrations in the coal ash were far lower than the permitted levels of hazardous substances in designated waste in Korea. In addition, a content analysis showed that the heavy metal content was lower than the level prescribed in the standards for area II levels of soil contamination. Since coal ash is recycled in cement kilns, levels of Pb, Cu, and Cd in the cement kilns were reviewed and compared against permitted levels of those heavy metals in other alternative fuels. Levels of Pb, Cu, and Cd in the coal ash were comfortably within the acceptable limits by Korean standards, but the level of arsenic was close to the limit. Given the fact that arsenic leached from the coal ash recycling process could have an adverse impact on both the environment and the human body, it is therefore necessary to monitor arsenic leaching from coal ash continuously . Levels of other substances that could be contained in coal ash, such as dioxin, PCBs , and PAHs, were also measured. The measurements showed that the levels of these substances were generally low or undetectable; therefore, the environmental impact of organic pollutants from coal ash recycling was considered insignificant.

세계 각국은 기후변화에 대응하기 위한 노력의 일환으로 재난관리시스템의 고도화를 활발히 전개하고 있다. 이러한 관점에서 특히, 문화재는 상대적으로 희소적 가치를 가지고 있고 재난에 대한 취약성이 높은 자산으로서, 효과적인 재난관리를 위한 시스템 구축의 필요성이 더욱 절실하다. 효과적인 문화재 재난관리시스템 구축을 위해서는 문화재 재난관리 관련 기초정보가 요구되는데, 이에 대한 체계화가 미흡하고 정보가 매우 빈약한 실정이다. 이에 본 연구에서는 효율적이고 체계적인 문화재 재난관리시스템 구축을 궁극적 목표로 설정하고, 이를 위해 관련 연구 및 정책동향을 종합적으로 분석하고, 주요 사례를 중심으로 시사점을 고찰하여 시스템 구축의 당위성을 검토하는 한편, 현황진단을 통해 시스템 구축의 기본방향을 설정함으로써 효과적인 시스템 구축을 위한 기반을 마련하고자 하였다.
