Risk based pollution level of Pb and Cd in metal contaminated soils depending on physicochemical properties of soil in a target site was assessed using biotic ligand model. Heavy metal activity in soil solution defined as exposure activity (EA) was assumed to be toxic to Vibrio fischeri and soil organisms. Predicted effective activity (PEA) determined by biotic ligand model was compared to EA value to calculate risk quotient. Field contaminated soils (n = 10) were collected from a formes area and their risk based pollution levels were assessed in the present study using the calculated risk quotient. Concentrations of Pb determined by aqua regia were 295, 258, and 268 mg/kg in B, H and J points and concentrations of Cd were 4.73 and 6.36 mg/kg in G and I points, respectively. These points exceeded the current soil conservation standards. However, risk based pollution levels of the ten points were not able to be calculated because concentrations of Pb and Cd in soil solution were smaller than detection limits or one (i.e., non toxic). It was because heavy metal activity in soil solution was dominant toxicological form to organisms, not a total heavy metal concentration in soil. In addition, heavy metal toxicity was decreased by competition effect of major cations and formation of complex with dissolved organic carbon in soil solution. Therefore, it is essential to consider site-specific factors affecting bioavailability and toxicity for estimating reliable risk of Pb and Cd.

안진성(Jin-Sung Ahn),권순우(Soon-Woo Kwon),윤재홍(Jae-Hong Yoon),박봉규(Bong-Gyu Park) 한국표면공학회 2006 한국표면공학회지 Vol.39 No.4

Incoloy alloy 909 is an Fe-Ni-Co based superalloy that is attractive for gas turbine engine applications. The absence of chromium, however, makes the alloy more susceptible to oxidation in high temperature. To improve the oxidation resistance aluminizing was performed by high activity low temperature pack cementation process. Aluminizing condition was examined with different times and temperatures. Optimum aluminizing conditions were at the temperature of 552℃ for 20 hrs. In the optimized condition, the thickness of the aluminized layer was about 20 ㎛. Also, the aluminized layer made the alloy to increase the resistance to the corrosion

Potential risk of heavy metals to various receptors including humans depends on the bioavailability of the heavy metals in soil. In this study, the heavy metal extraction methods using 0.1N HCl and aqua regia were compared with the Tessier's sequential extraction method to assess whether these two methods can be used to determine the plant-available heavy metal concentrations. The contamination characteristics of copper (Cu), cadmium (Cd), lead (Pb), and arsenic (As) found in soils collected from 75 sites around the closed Janghang smelter were analyzed by extracting heavy metals using 0.1 N HCl, aqua regia, and the Tessier's sequential extraction method. The portion of metals bioavailable to plants is considered as the sum of the fraction 1 (exchangeable) and the fraction 2 (carbonates binding) of the Tessier's 5-step sequential extraction method, which were determined to be 3.1 ${\pm}$ 3.82, 0.6 ${\pm}$ 0.15, 20.6 ${\pm}$ 18.78, and 7.0 ${\pm}$ 6.48 mg/kg for Cu, Cd, Pb, and As, respectively, in this study. When the extraction using aqua regia and the Tessier's extraction method were compared, the extracted Cu and Pb concentrations did not show significant differences, whereas the extracted Cd and As concentrations showed significant differences. These results indicate that the portion of Cd and As in the fraction 5 of the Tessier's sequential extraction can not be extracted using aqua regia. Using aqua regia, which is the official test method, higher concentrations of Cu, Cd, Pb and As were extracted than the sum of the fraction 1 and 2. The results show that only 9, 40, 39 and 10% of Cu, Cd, Pb and As using aqua regia can be uptaken by plants (i.e., plant-available). Using 0.1N HCl, the portion of Cd equivalent to about 66% the fraction 1 could be extracted, while, with Pb, the portion of the fraction 1 and about 90% of the fraction 2 could be extracted. With As, the portion equivalent to the fraction 1, 2 and 79% of the fraction 3 was extracted, while with Cu, the portion equivalent to the fraction 1, 2, 3 and 20% of the fraction 4 was extracted using 0.1N HCl.

본 연구의 목적은 도시공원과 녹지공간의 이용과 미적 측면에서 도시민들이 중요하게 가치를 두고 있는 요인들을 평가하고, 다양한 공원녹지 요소에 대해 이용자 만족도 변화를 다루는 방법을 찾는 것이다. 이를 위해서 본 연구에서는 안양시의 1999년과 2007년의 환경의 질을 평가하기 위해 교류적 접근방법을 이용한 동적모형과 공원녹지만족도 개념모형을 발전시킨다. 그리고 실증적 연구방법으로 1999년과 2007년의 공원녹지 환경 조사와 1999년의 573개, 2007년의 982개의 설문을 포함한다. 분석결과, 첫째, 공원녹지만족도의 가장 중요한 요인은 '도시공원'이고, 그 다음으로 '도시경관'이었다. 둘째, 모형에서 공원녹지만족도는 도시거주성과 경관의 질을 포함한 도시환경의 질적 만족도의 원인이 된다. 셋째, 요인분석결과, 평가인자는 도시경관, 도시녹지, 선형시설, 도시공원, 하천녹지, 산림녹지의 6개 요인이었으며 2007년에는 시민들이 참여한 '안양천 되살리기 운동'으로 인해 하천녹지 요인이 새로이 나타났다. 넷째, 교류적 관점에서 환경변화 결과는 시민들의 태도변화 측면, 안정성 측면의 양면을 보여주고 있다. 만족도는 향상되었지만 대부분의 요인에서 만족-불만족 항목의 패턴은 변화되지 않았다. 녹도를 포함한 하천녹지와 선형시설(보행자전용도로, 자전거도로, 조깅로 등)은 긍정적으로 변화되었다. 2007년에 공원녹지만족도는 안양시의 노력과 시민운동으로 조성된 도시공원 및 하천과 녹도로 인해 두드러지게 향상되었다. This study aims to examine what factors citizens value in urban parks and green spaces in terms of usage and aesthetic value and to find ways to deal with the changing patterns of user satisfaction for these various green elements. To achieve this, the study developed a dynamic model employing a transactional approach to evaluate environmental quality for 1999 and 2007 in Anyang City as well as a conceptual model of parks and greens satisfaction. This study relied on an empirical study method including the 1999 and 2007 green conditional survey and citizen questionnaires totaling 573 in the year 1999 and 982 in the year 2007. As a result, first, the factor 'urban parks' is the most important factor and 'cityscape' is the second most important factor in parks and greens satisfaction(PGS). Second, PGS in turn causes environmental quality satisfaction(EQS), which is related to two items--'urban livability' and 'aesthetic quality'--in the model. This means that PGS is the intervening variable of urban livability. Third, the factor analysis resulted in six factors: cityscape, urban green, linear facilities, urban parks, riverside green, and urban forest. 'Riverside green' emerged as a factor in 2007 as a result of public participation in the 'Anyang River Revitalization Project'. Fourth, through a transactional view, the environmental changes result in either a change in or stability of public attitude. The levels of satisfaction were elevated but patterns of satisfied-unsatisfied items remained unchanged for most factors. The perception of riverside a greenway and linear surface facilities(pedestrian walkways, biking and jogging trails, etc.) have changed positively. PGS changed significantly in 2007, as a result of urban events and development, including parks, rivers and greenways which were built through the joint effort of the local government and civic participation.
