The physical and chemical properties of cover soils of 10 waste landfill sites in Kyonggi-Do area, where social circumstances at present forces to consider the reuse of landfill, were investigated to provide the informations of soil environment which are necessary to establish the appropriate ecological restoration plan of waste landfills. The pH and electrical conductivity of soils were higher in landfills sites than in reference sites (area around landfill sites), indicating the salt accumulation in surface soil. However, total-N and organic matter contents were lower in landfills sites than in reference sites. In landfill sites, the total-N and plant available-P contents were less than 0.15% and 20mg/kg, respectively. Exchangeable cations (K, Ca, Mg and Na) and heavy metal (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) contents varied between the landfill sites, but were higher in landfills sites than in reference sites. The major exchangeable cation of soil was Ca. Heavy metal contents were much lower than the critical concentration which phytotoxicity is considered to be possible and the standard for agricultural land of Korean Soil Environmental Preservation Act. Therefore, the proper soil management plan to increase the soil fertility is recommended for the ecological restoration of landfill using natural or artificial vegetation.

토양오염기준은 토지이용별 또는 오염노출경로별 오염토양의 조사, 평가 및 복구를 위한 유용한 지침으로 이용될 수 있다. 이 연구에서는 한국을 포함한 몇몇 국가의 토양오염기준을 특히 중금속에 주안점을 두고 검토하였다. 또한 국내 일부 폐광산 지역의 환경오염 조사결과를 토양오염기준과 비교하며 평가하였다. 영국, 네덜란드, 독일, 캐나다, 일본 등의 국가에서는 복구우선순위 선정과 인체건강 및 생태계 보전을 위한 오염토양의 선별수단으로 토양오염기준을 개발하여 왔다. 국내에서는 1996년 토양환경보전법(시행규칙)의 시행에 따라 토양 오염기준 설정과 특정토양오염유발시설의 관리, 정기적 토양오염도 조사를 실시하고 있으며 이후 2001년 보완 개정되어 토양오염물질의 확대적용과 토양오염 조사, 관리 및 복원 방법의 보완이 이루어진 바 있다. 그럼에도 불구하고 현 중금속(Cd, Cu 및 Pb)의 오염기준을 적용할때 폐광산 지역의 폐기물과 이에 오염된 토양의 경우 다량의 중금속을 함유하고 있지만 오염지역으로 규정되지 않을 수도 있다. 이 연구 결과, 0.1N 염산용출법은 중금속의 토양 내 화학적 형태 중 일부 교환성 및 환원성 형태만을 추출하며 황화물 형태를 충분히 용출하지 못하고 있는 것으로 나타났다. 또한 장기적인 환경조건 변화에 따른 토양 내 중금속의 용출성 변화를 평가하기 위해서는 강산추출법이 요구되어진다. 따라서 폐광산지 역의 중금속에 의한 토양오염의 타당한 환경평가 결정을 위해 현 분석기법 외에 총함량 분석방법의 병행적용과 이에 따른 새로운 오염기준 설정 등이 필요한 것으로 제시되었다.

This study performed from 2002 October to 2003 April. The samples were taken at 66 sites, divided into the 6 sections functionally in the southern part of Seoul such as Yangchon-gu, Kangseo-gu, Kuro-gu, Yeongdengpo-gu, Kwanak-gu, Dongjak-gu, Seocho-gu, Kangnam-gu, Songpa-gu, and Kangdong-gu. The result of research showed that each property soil was pH 4.7∼9.5, Cd; 0.391 mg/kg (0.011∼l.081 mg/kg). Cu; 12.35 mg/kg (0.061∼73.62 mg/kg), Pb; 13.04 mg/kg (N.D.∼61.85 mg/kg), Hg; 0.0866 mg/kg (N.D.∼1.353 mg/kg), F; 206.8 mg/kg(47.1∼561.1mg/kg). The minimum and maximum of the concentration with functional soils were Cd; 0.632 mg/kg for multi-purposed soil,0.079 mg/kg for schools, Cu; 21.35 mg/kg for roadside, 2.159 mg/kg for schools, Pb; 24.70 mg/kg for roadside, 1.030 mg/kg for schools, Hg; 0.1780 mg/kg for multi purposed, 0.0087 mg/kg for schools. Especially F was the high concentration at the hills. Also the concentration of Cd, Cu, Pb, Hg and F at school Zone was detected such as low. area of schools area was detected the low concentrations as the items of Cd, Cu, Pb, Hg, and F. The average concentrations of metals and fluorine in the survey area were below the Preliminary Standard of the Soil Preservation Acts in Korea. To evaluate the soil quality of these area showed as a good qualified results. The results of SQPI (Soil Quality Pollution Index the qualified results as much as 86.4%.

With the enactment and enforcement of the 「Public Records and Archives Act」, the Tottori Prefectural Archives newly enacted the "Records Management Ordinance" through a comprehensive review of the previous archive function. In accordance with this ordinance, which came into effect in April 2012, Tottori Prefecture expanded the records management institutions (Public Security Committee and Police Headquarters, etc.) A series of archive systems were improved, such as the expansion and reinforcement of the authority to appraisal and select. In addition, the Tottori Prefectural Archives went further and implemented the "Ordinance on the Preservation of Historical Documents, etc." from April 2017. Through this, the municipalities unit basic local government's record management support work was set as a unique function of the local archive, and a linkage and cooperation system was established for the preservation of private records of the prefecture area as well as the basic local area together with cultural heritage institutions such as museums and libraries. As a reference case that continuously guarantees the performance of various activities based on the mission and vision of the local archives in Korea that aim for 'autonomy of records' on the poor archival culture soil, it is worth paying attention to the case of continuous record management reform of the Tottori Prefectural Archives through the enactment of the original role and function of the archive.
