국내에서는 국토개발 목적으로 토양을 반입하고 잔토 및 사토 처리를 위해 토양을 반출하고 있으나, 토양오염에 대한 고려 없이 특정 부지로 토양이 반입되고 있는 실정이다. 이에 본 연구는 토양의 이동으로 인한 오염 확산을 방지하고 오염발생 부지에서의 정화책임을 명확하게 하기 위한 목적으로, 국내 반입토양 관리 현황을 살펴보고 국외 관련 제도를 분석하여 국내에서 토양 반입 부지의 관리체계를 효율적으로 운영하기 위한 방안을 고찰하였다. 본 연구에서는 반입되는 토양의 합리적인 이동 관리체계를 마련하기 위한 방안으로 자율적 규제, 의무적 규제, 단계적 규제를 제안하였다. 향후 국내에서 토양 반입부지에 대한 명확하고 합리적인 관리체계를 성립하기 위해서는 본 연구에서 제안한 것과 같이 현재 토양환경 보전법이 가지고 있는 법 제도적 한계점을 개선하여 토양 반입 부지에 대한 규제 및 지침을 빠른 시일 내에 보완해야 할 필요성이 있다.

The purpose of this study was to analyze their status of underground storage tank(UST) facilities and level of soil contamination, and to establish its management criteria. DB program was developed to analyze the correlation between specific characteristic of UST and level of soil contamination. For a suitable management of UST, leakage monitoring and inspection method of UST was investigated. Inspection period was established based on the leakage rate. The most dominant factor for leakage seemed to be caused by the corrosion. Therefore, main factor, construction method and installation year of UST, and corrosion protection system were suggested for optimal protection of UST. Considering the present management status of UST in Korea, inspection and management criteria of UST should be accomplished in term of contamination protection of leakage, and flexible regulation act should be introduced for each specific site.

Environmental pollution is continuously increasing with the economic growth and industrial development. With this trend, soil and groundwater pollution problem has been surfaced as important social issues. Recently, Korean government promulgated the Soil Environment Conservation Act. But there are many problems to control sound soil quality management. Anthropogenic source of pollution such as waste landfill, pesticides, fertilizer, underground storage oil tanks is important as well as natural source such as acid rain and forest fire. The regulation should be expanded to include groundwater preservation as well as soil quality, because soil pollution is closely related to groundwater pollution. Therefore, legal regulations must be expanded to these facilities and take into account technical feasibility and finance.

국내 사면안정성 설계기준은 우기 건기시로 제안되어 사용되고 있지만, 한계평형해석의 결과로 산출되는 안전율이 외부조건에 의해 변화되며, 특정한 변곡점이 없기 때문에 사전에 안전을 확보하기 어렵다는 점에 착안하여 경보발령, 서행 및 열차정지 등과 같은 안전규정의 설정이 가능한 대안을 검토하였다. 이를 위하여 본 연구에서는 불포화토질역학과 신뢰성해석에 기초하여 현행 안전율을 보조할 수 있는 부가적인 지표를 도입하였다. 강우침투에 따라 안전율과 신뢰지수는 지수함수형태로 감소하는 특징을 보이며, 파괴확률은 누적확률분포함수 형태로 증가함을 확인할 수 있었다. 본 연구에서 검토한 부가지표인 파괴확률 변화속도는 현재의 기준 안전율 부근에서 명백한 변곡점을 갖는 특징이 있다. 이를 이용하면 사면의 안전관리와 모니터링 시스템에 대한 적정 규정으로 적용이 가능할 것으로 판단된다.

This study was conducted to identify transition characteristics of mercury in several selected medicinal plants and to find the appropriate management for production of safety food. Cultivated soils and medicinal plants were collected at 29 sites for Angelica gigas (Korean angelica root), 68 sites for Platycodon grandiflorum (Balloon flower), 35 sites for codonopsis lanceolata (Deoduck), 36 sites for Dioscorea batatas (Chinese yam), 32 sites for Rehmannia glutinosa (Foxglove), 16 sites for Cnidium officinale makino (cnidium), and 26 sites for Astragalus membranaceus (milk vetch root) during the harvest season of 2013. Mercury in the soils and medicinal roots were analyzed with a Direct Mercury Analyzer. Average content of mercury in soils cultivated medicinal plants was $0.023mg\;kg^{-1}$ (range: from 0.003 to $0.074mg\;kg^{-1}$) and average content of mercury in medicinal plants was $0.003mg\;kg^{-1}$ (range: from 0.001 to $0.011mg\;kg^{-1}$), indicating that mercury in the surveyed soils and medicinal plants were not exceeded the Korean regulation.

Total extraction method and environmental standards for heavy metals in soils were revised in regulation recently. In case of Area 3, as the law amended, the soil pollution level has gone up to 4 to 13 times higher depending on the type of heavy metal. In this study, it compares the properties of heavy metals of soil by sequential extraction and total extraction methods depending on the analysis method, using the soil around mine. In case of arsenic, the soil pollution level has gone up to 4 times higher, but 6 to 10 times in the sample soil. Also, according to the results of portability evaluation depending on the type of existence form of heavy metal it exists as residual form in mine waste rock, which is less likely to move, while it exists as migrated form in tailing. Therefore, it should be considered to evaluate the soil pollution and decide the contaminated bounds depending on the existence form of heavy metals on soil to restore the polluted soil.

In recent years, the sales of bottled spring water (BSW) have been drastically increasing in Korea and other countries, which accompanied great interests in conservation and reclamation of natural mineral water (NMW). In this study, management and research activities on NMW in Europe, USA, and Codex Alimentarius were reviewed. In each region, NMW is regulated with its own quality standards that differ from ordinary drinking water, and management actions are strictly implemented to protect water resources and to secure quality of NMW. Many studies on NMW were carried out for monitoring inorganic constituents including major and trace elements in national levels for bottled NMW, groundwater, and tap water in other countries. In Korea, NMW became commercialized in 1995 when BSW was legally approved as a drinking water. To further promote utilization of various types of NMW in Korea, regulations and policies for NMW need to be revised in accordance with international NMW management trends. Further, studies of NMW that compile a comprehensive set of physical and chemical parameters of NMW are also needed to properly understand occurrences, hydrogeological and geochemical processes of NMW, as well as to evaluate its potential use as a natural resource.

BACKGROUND: Increase of heavy metals in agricultural ecosystem has become a social issue nationwide as it is related to public health. This review was performed to find out more systematic and integrated future researches on heavy metals using up to date articles published in the Korean journals related to agricultural environment. METHODS AND RESULTS: Researches on heavy metals in agricultural soils and plant uptake were categorized by the establishment of criteria, analytical methods, monitoring, management of source, characteristics and behavior in soil, plant uptake, bioavailability affecting physico -chemical properties in soil, risk assessment and soil remediation. In the early 1990s, the monitoring for heavy metals in soil has been widely performed. Accumulation of heavy metals in contaminated soil and availability to plants has also attracted interests to study the soil remediation using various physico-chemical methods. The phytoavailability and phytotoxicity of heavy metals have been mainly studied to assess the safety of agro-products using risk assessment techniques in the 2000s. CONCLUSION: Future direction of research on heavy metal in agricultural environment must be carried out by ensuring food safety and sustainability. A steady survey and proper management for polluted regions should be continued. Law and regulation must be modified systematically. Furthermore, studies should expand on mitigation of heavy metal uptake by crops and remediation of polluted fields.
