Laboratory experiments were peformed to understand physical properties of soil-cement column under the influence of acidic flow including metal contaminants and its retaining capacity against metal migration. The contaminant used in this study was nitric acid with Cu and Cd. The Permeability of soil-cement column decreased when pH of the column began to drop below 12. Decreases in pH led to significant reduction of compressive strength of clayey soil-cement specimen, while relatively marginal reduction for sandy soil-cement specimen. The metal contaminants did not leachate from soil-cement column until pH of soil-cement dropped below 7∼8 for Cu and 9∼10 for Cd. Metal contaminants were precipitated and trapped inside the soil-cement column at pHs higher than those mentioned as verified with metal analysis and visual inspection. This indicated that soil-cement column not only performs well as a cut-off wall, but also helps alleviating the level of contamination of the surrounding environment.

Dust samples were collected from 17 middle and high schools in the Jeonju-city. heavy metal concentrations were determined for the dry-deposited dusts from indoor and outdoor of classroom and playground of each sampling site. Concentrations of Cd, Cr, Cu, Ni, Pb and Zn in indoor\`s dusts were highly concentrated. Also heavy metal concentrations in outdoor\`s dusts were similar to that of indoor\`s dusts. Concentrations of Cd, Cu, and Zn in the dusts were much higher than the world average contents in soil and environmental orientation value. These levels are similar to those of the dust samples at middle schools located at Kangseo-gu and Yangchon-gu , Seoul. Playground dusts in 6 schools exhibited the enhanced heavy metal pollution with a pollution index (by Kloke) greater than 1.0. Most indoor and outdoor dusts exhibited the enhanced heavy metal pollution with a pollution index(by Cullbard et al.) greater than 1.0.

마산만과 진해만 해저에서 각각 31개와 65개 표층퇴적물을 채취하여 중금속(Al, Fe, Mn, Cr, Cu, Ni, Zn, Pb, As, Cd)을 분석하였다. 중금속 함량은 우리나라 주변의 만 및 하구 퇴적물에 비해 마산만에서 Fe, Cr, Cu, Zn, Pb, Cd, As 등이 높았고 진해만에서 Mn이 높았다. Cu, Zn, Pb, Cd, As는 항구 및 산업시설이 위치한 마산만 해안에서 매우 뚜렷한 증가를 보였으며 공간분포를 통한 오염물질의 근원지 추정이 가능하였다. 오염에 의한 중금속 농축은 지각의 함량을 배경농도로 한 농축비에 근거할 때 진해만은 국지적으로, 반면에 마산만은 넓은 지역에 걸쳐 활발히 진행된 것으로 확인되었으며 특히 Cu, Zn, Pb 및 Cd의 농축비가 대비되었다. As, Cd, Cr, Cu, Pb, Ni, Zn 함량을 중금속 환경기준에 적용한 결과 진해만 시료의 일부와 마산만 시료의 거의 대부분이 주의기준(NOAA ERL, EC TEL, ANZECC ISQG-low, Hong Kong ISQV-low)을 초과하였으며, Cu 및 Zn 함량은 일부 마산만 시료에서 관리기준(NOAA ERM, EC PEL, ANZECC ISQG-high, Hong Kong ISQV-high)을 초과하였다. $I_{geo}$ 값에 근거한 마산만의 중금속 오염은 Fe, Mn, Cr, Ni는 우려할 만한 수준이 아닌 반면 Cu, Zn, Pb는 강한 오염단계에 직면해 있거나 진입해 있으며, Cd는 시료의 87.1%가 강한 오염단계 이상의 심화된 오염상태로 파악되었다.

Four types of land use were selected for sampling and study with different characteristics of heavy metal contamination during the period from August 1998 to June 2000. A series of studies have been carried out concerning the physicochemical characteristics of the sediments settling down in a gully pot to evaluate the contamination of Pb, Zn, Cd, Co, Cr and Cu. An examination of six elements indicated that Zn, Cu and Pb were the heavy metals severely impacted by anthropogenic input in Seoul. An assessment of 60 volatile organic compounds (VOCs) in urban runoff and ground water was conducted based on samples collected from 31 sites and 12 wells, respectively, in Seoul City. The higher levels of alkyl benzenes in urban runoff indicated that Seoul areas were mainly contaminated through traffic sources.

Metal problems in herbal medicine are not regulate properly by law and public management around world country until this time. General people belief as safety about herbal since natural material. And almost all persons can also purchase by their-self and use by self-prescription in reality. As this result herbal medicines can always occur acute and chronic toxicity by not proper use problems, side-effect and overdose. Heavy metal toxic diseases in historical view point was big accidents that didnot forget including minamata and itai-itai in Japan. These accident's teach to us must not use toxic metal level and not include or at least Pb Hg As Cd in all kind material use and intake by people, especially herbal. Herbal contamination research is beginner state that had not many papers until nowadays. Even if this pan had some papers, it had negative result and bigger and larger than problems level because of one way research trend of not many sample case-report and screening test of dried herbal form in chiefly. Many persons have afraid and risk thinking about herbal, animal and minerals since these cause. Further research related this subject will be needed at fact of epidemiology including case-control and cohort study for more precision research affecting in short and long term intake of oriental medicines

Concentrations of Al, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn were determined in four arctic brown algae (Laminaria saccharina, L. digitata, Alaria esculenta, Desmarestia aculeata) in an attempt to examine for their metal accumulation capacity and also to assess their contamination levels. Macroalgae were collected from shallow subtidal waters (<20m) of Kongsfjorden (Kings Bay) on Spitsbergen during the period of the late July to early August 2003. Metal concentrations highly varied between sampling sites, species and tissue parts. Input of melt-water laden with terrigenous sediment particles seemed to have a large influence on baseline accumulations of some metals (Al, Fe, Mn, Pb etc.) in the macroalgae, causing a significant spatial variation. There were also significant concentration differences between the young and old tissue parts in L. saccharina, L. digitata and A. esculenta. While Al, Fe, Mn, Pb were higher in the perennial parts (stipes and holdfast below meristematic region), Cd and As concentrations were significantly higher in the young blades above the meristematic region. Zn and Cr, on the other hand, showed little differences between the tissue parts. The highest metal concentrations were found in D. aculeata, which seems to be due to its filamentous fine branches leading to high surface/volume ratios. The lowest concentrations were found in the two Laminaria spp., the blades of which are thicker than D. aculeata and A. esculenta. No distinct signs of contamination were detected in the brown algal species analyzed. Added to this, the results of the present studies suggest the potential utility of L. saccharina, L. digitata and A. esculenta as biomonitors for metal pollution monitoring in this area.

Current methods of evaluating soil contamination by heavy metals rely on analyzing samples for total contents of metals or quantities recovered in various chemical extracting solutions. Results from these approaches provide only an index for evaluation because these methodologies yield values not directly related to bioavailability of soil-borne metals. In addition, even though concentrations of metals may be less than those required to cause toxic effects to biota, they may cause substantial effects on soil chemical parameters that determine soil quality and sustainable productivity. The objective of this research was to characterize effects of Cu or Cd additions on soil solution chemistry of soil quality indices, such as pH, EC, nutrient cation distribution and quantity/intensity relations (buffer capacity). Metals were added at rates ranging from 0 to 400 mg/kg of soil. Soil solution was sequentially extracted from saturated pastes using vacuum. Concentrations of Cu or Cd remaining in soil solutions were very low as compared to those added to the soils, warranting that most of the added metals were recovered as nonavailable (strongly adsorbed) fractions. Adsorption of the added metals released cations into soil solution causing increases of soluble cation contents and thus ionic strength of soil solution. At metal additions of 200~400 mg/kg, EC of soil solution increased to as much as 2~4 dS/m; salinity levels considered high enough to cause detrimental effects on plant production. More divalent cations (Ca+Mg) than monovalent cations (K+Na) were exchanged by Cu or Cd adsorption. The loss of exchangeable nutrient cations decreased long-term nutrient supplying capacity or each soil. At 100 mg/kg or metal loading, the buffering capacity was decreased by 60%. pH of soil solution decreased linearly with increasing metal loading rates, with a decrement of up to 1.3 units at 400 mg Cu/kg addition. Influences of Cu on each of these soil quality parameters were consistently greater than those of Cd. These effects were of a detrimental nature and large enough in most cases to significantly impact soil productivity. It is clear that new protocols are needed for evaluating potential effects of heavy metal loading of soils.
