This study investigated the change of metal contamination levels according to amendment of enforcement regulation of the Soil Environmental Conservation Act in Korea. As an analytical result of 87 samples in abandoned metallic mine area, the extracted amount of As, Pb and Cu with aqua regia was 4.3~29.6 times higher than that with hydrochloric acid extraction and the number of samples, which contamination levels were found to exceed soil contamination standards, was also increased. On the other hand, in case of Cd, Zn, and Ni, the number of samples, which contamination levels were found to exceed soil contamination standards, was decreased or similar. These results can be used as a preliminary material in comparison between the soil pollution data accumulated previously and the data obtained by the revised standard method for the examination of soil pollution.

This study was conducted to grasp the effect of afforestation of cut slope using coir blocks on the improvement of scenery and the management of non point pollution source. Total four experimental tanks such as general soil slope, coir blocks, installation slope, slope refilling the inside of coir blocks slope with pebble, slope refilling the inside of coir blocks with soil and plant were installed, pollution source water was supplied and the possibility of reduction management of non point pollution source was analyzed at four items of COD, SS, T-N, T-P and main results drawn from this study are as follows. In conclusion, biodegradable materials like coir blocks and soil and plant layers are judged to be helpful in reduction management of non point pollution source inflowing to water space from land area. Thus, the reduction of non point pollution source occurring at land area is thought to be fully controlled at the cut slope, the space prior to inflowing to water ecological space like a stream or a swamp area.

The aims of this study were to determine concentrations of selected metals in Asian and non-Asian dust collected in Daejeon, Korea between February 2008 and December 2008 and to estimate the pollution level. The geochemical analyses of Asian dust (AD) and Non Asian dust (NAD) show that the mean concentrations of As, Cd, Cu, Pb, Zn, Zr, Sb, Mo and S reached levels up to 16, 209, 31, 43, 81, 28, 31, 122 and 302 times higher, respectively, than those in uncontaminated Chinese desert soils. These results indicate that both AD and NAD serve as an atmospheric repository for trace and heavymetal accumulation. The the enrichment factor (EF) and pollution index (PI) show that AD and NAD were severely contaminated by S, Mo, Zr, Cd, Pb, Zn, Sb, Cu, and As. All indices for these metals showed either strong or notably high level of pollution relative to Chinese desert soil, principally due to the severe atmospheric pollution derived from anthropogenic activities in heavily industrial Chinese cities. Therefore, Mo, Cd, Zr, As, Cu, Sb, Pb, and Zn are the ones most strongly affected by anthropogenic inputs such as airborne pollutants.

중금속으로 오염된 토양질을 평가할 수 있는 토양오염지표(SPI, Soil Pollution Indices)를 고안하였다. 토양오염지표는 토양을 농경지, 주거지, 공원 여가지, 공장 산업지역으로 분류하고, 토양의 이용 용도별 토양오염기준을 이용하여 토양의 다기능성을 고려하였다. 토양의 이용 용도별로 토양중 5종류의 중금속 및 비소의 농도가 생태계에 미치는 영향을 나타내는 수리적 수치를 가산한 토양오염 점수(SPS, Soil Pollution Score)를 산출하였다. 토양의 이용 용도별로 산출된 토양오염점수에 따라 토양을 4등급의 토양오염등급(SPC, Soil Pouution Class)으로 구분하였다. 1등급은 점수 <100, 2등급은 점수 100-200, 3등급은 점수 >200-300, 4등급은 점수 >300으로 설정하였다. 토양오염점수와 토양등급의 실용화 가능성을 타진하기 위하여 1994년 토양측정망의 운영결과로 도출된 5종류의 중금속 및 비소 농도를 이용하여 토양중의 중금속 농도를 토양오염점수, 토양등급으로 환산하였다. 토양 측정망 측정지역의 비소 및 중금속 농도를 토양오염기준과 비교할 때, 대상지역의 토양환경은 대부분이 건전한 상태로 판단되나, 토양측정 망 측정지 점 의 약 3.0∼4.0%는 토양오염이 우려되거나 오염된 지역으로 판단된다. 토양측정망 측정 지역의 평균 토양오염 점수는 66.2로 토양측정망 대부분이 지역이 건전한 상태를 유지하는 것으로 나타났다. 토양오염점수를 4등급으로 분류하였을 때, 전체 측정지역에서 1등급(토양질 건전지역) 87.0%, 2등급(토양질 검증지역 1) 9.4%, 3등급(토양질 검증지역2) 2.4%, 4등급(토양질의 오염우려지역) 1.2%로 산출되었다. 토양오염지표로 고안된 토양오염점수와 토양오염등급은 오염물질에 의한 토양의 오염상태를 종합적으로 판단할 수 있는 방법으로 평가되며, 토양오염지표를 개발한 방법은 5종류의 중금속 및 비소를 포함하여 유 무기 오염물질에 의한 토양오염의 판단에 적용할 수 있을 것으로 사료된다.

The Ministry of Environment has been working to reduce the impact on biodiversity, ecosystems, and social costs caused by soil runoff from highland Agricultural fields by setting up non-point pollution source management districts. To reduce soil loss, runoff path reduction technology has been applied, but it has been less cost effective. In addition, non-point pollution sources cause environmental conflicts in downstream areas, and recently highland Agricultural fields are becoming vulnerable to climate change. The Ministry of Environment is promoting the optimal management plan in earnest to convert arable land into forests and grasslands, but since non-point pollution is not a simple environmental problem, it is necessary to approach it from the aspect of NbS(Nature-Based Solution). In this study, a scenario for applying the nature-based solution was established for three subwatersheds west of Haean-myeon, Yanggu-gun, Gangwon-do. The soil loss distribution was spatialized through GeoWEPP and the amount of soil loss was compared for the non-point pollution reduction effect of mixed forests and grasslands. When cultivated land with a slope of 20% or more and ginseng fields were restored to perennial grasslands and mixed forests, non-point pollution reduction effects of about 32% and 29.000 tons compared to the current land use were shown. Also, it was confirmed that mixed forest rather than perennial grassland is an effective nature-based solution to reduce non-point pollution.

The concerned party of purification liability in a soil pollution is an owner or occupant of a contaminated site. But when we don't appoint the polluter or he can't do a cleanup, municipal put in effect the purification. In such a case, another parties who are related to the contamination ought to the liability. The province of responsible parties, therefore, is required to extend to an owner or operator of a facility, a carrier and lender

여천공단의 대기오염이 산림생태계에 미치는 영향을 파악하기 위하여 공단의 남단에 위치한 남해화학주변과 그 지역에서 2km, 4km, 6km, 8km 및 10km 떨어진 지점을 선정하여 산림토양의 화학적 특성, 탈질균 및 황산환원균 동태와 지의류 출현도를 비교하였다. 여천공단 주변지역의 토양은 적황색 산림토양군(R Y)에 속하는 토양이었으나 같은 산림토양군에 속하는 토양에 비해 pH가 매우 낮았다. 산림토양의 pH가 낮음으로 인해 C/N비가 15~25의 범주에 있음에도 불구하고 유기물의 분해 등 무기화에 관여하는 미생물의 활력이 낮아서 유기물함량이나 전질소함량은 상대적으로 높았다. 공단 인접지역에서 4km 지점에 이르는 곳까지의 토양 화학특성이 6km 이후 지역에 비해 대기오염 피해도가 심하게 나타났으나 탈질균 및 황산환원균의 분포량 차이에 따른 피해도 구분은 어려웠다. 한편, 지의류는 산림토양에 반영된 대기오염도의 차이에 비해 확연한 결과를 나타냈으며, 특히 엽상지의류는 바위에 붙어 사는 지의류에 비해서 더 민감한 반응을 나타냄을 확인할 수 있었다.

본 연구에서는 강원도내 4개의 폐금속광산에서 발생되는 광미와 주변 토양의 중금속 오염현황 및 오염도를 평가하였다. 광미와 주변 토양의 오염정도는 총 중금속농도 기준으로 원동>제2연화>신예미${\fallingdotseq}$상동 순이었으며, 이들 광미는 배경토양 및 Kloke 값보다 각각 $1.2{\sim}78.2$와 $1.1{\sim}80.6$배가 높은 농도로서 주변 토양을 오염시키고 있었다. 광미내 대다수 중금속의 화합물형태는 잔류성이 대부분이었다. 비잔류형태 화합물에서는 상당부분이 환원성과 산화성이어서 장기간에 걸쳐 산화환경조건에 따라 중금속이 유출될 것으로 보이며 특히, 제2연화의 Cd은 교환성과 탄산염 화합물이 쉽게 유출되어 단기간에 주변 환경을 오염시킬 가능성이 클 것으로 판단된다. 우리나라 토양오염기준치의 초과여부 검토결과 많은 시료에서 토양환경보전법의 우려기준 및 대책기준 이상인 것으로 나타나 이에 대한 처리대책이 필요하였다. PI에 의한 오염도평가에서는 4개의 광산지역 모두 1.0 이상보다 훨씬 높아 오염정도가 심각하였으며 복원시 최우선 광산은 원동이었다. 또한, DI에 의한 복원수준정도 평가결과에서 원동광산은 단기간에 유출 가능한 교환성부터, 나머지 광산은 중 장기간에 걸쳐 유출되는 환원성부터 우선적으로 제거해야 할 것으로 나타났다.

The escalating growth of industrial sectors has led to a pervasive global problem—oil pollution, particularly in industrial areas. The release of substantial volumes of oil and its by-products into the environment has resulted in extensive contamination. Multiple factors contribute to the entry of these substances into water bodies and soils, thereby inflicting irreparable consequences on ecosystems, natural resources, and human health. Consequently, it becomes imperative to comprehend the characteristics and behavior of oil pollution, anticipate its impacts, and develop effective mitigation strategies. Understanding this intricate issue requires considering the physicochemical properties of the environment, the interactions between oil and sediments, and biological factors such as evaporation and dissolution. Although the oil industry has brought about remarkable advancements, its activities have raised significant concerns regarding pollution from extraction and production processes. Oil-rich nations face a particularly challenging predicament of soil pollution caused by petroleum compounds. The areas surrounding oil exploration mines and refineries often endure contamination due to oil leakages from storage tanks and transmission lines resulting from deterioration and damage. Investigating the dispersion of such pollutants and devising methods to remediate petroleum-contaminated soil represent crucial and intricate issues within the realm of environmental geotechnics.
