농산 폐기물인 Allium속 뿌리를 이용한 Ni와 Pb 이온 제거

김성조,백승화,김운성,문광현 한국식품영양학회 1998 韓國食品營養學會誌 Vol.11 No.6

농산물의 갈무리시 발생되는 건조한 마늘, 쪽파 및 대파 뿌리 분말을 흡착제로 이용하여 수용액 중 이온 상태로 존재하는 Ni과 Pb의 흡착력을 시료의 입자별, 중금속의 농도별, 용액의 온도별, pH별로 분석하였다. 중금속 이온들은 흡착제의 입자크기가 작을수록 흡착률이 높았고, 그중 마늘뿌리가 Pb에 대해 높은 흡착력을 나타냈다. 수용액중 중금속 농도가 높을수록 중금속들이 흡착되는 양이 증가하였고, 흡착률은 흡착제와 중금속의 종류에 따라 차이가 있었다. 온도의 증가는 쪽파와 대파에서 Ni과 Pb가 감소되었다. 알칼리 조건에서 비교적 흡착이 잘 되는 중금속은 Ni이며, 중성과 산성조건에서는 Pb의 흡착량이 높았다. A batch experiment was conducted to evaluate the removal capacity of welsh onion(Allium fistulosum L.), shallot(Allium ascalonicum L.), garlic(Allium sativum L.) roots as an adsorbent for Ni and Pb in aqueous solution. One gram of the dried Allium root powder was reacted in 100ml of solution containing 10㎎ of each heavy metal and effects of metal concentration, pH, temperature, and size of adsorbent on the removal efficiency were evaluated. The results were as follows : The amount of adsorption of heavy metal ions were higher with the smaller particles size of adsorbent. Garlic root was high adsorption capacity of Pb, especially. The higher concentration of heavy metal solution was, the more amount of adsorption of heavy metals was. The adsorption ratio was differed from a kind of heavy metal. As the temperature increased, the amount of adsorption of Ni and Pb by shallot and welsh onion were decreased. The amount of adsorption of Ni was high under alkali conditions but the amount of adsorption of Pb was high under neutral and acidity condition.

金成朝,李甲湘,李基炫,白承和 圓光大學校 1993 論文集 Vol.27 No.2

靈芝載培에 있어서 一般的인 栽培法을 改善하여 靈芝의 收穫量을 높이고 品質向上을 시킬 目的으로 菌絲의 活着條件, 種菌接種 時期 및 方法, 버섯培養地의 土養種類 등을 달리하고, 栽培舍 構造設備을 改良하여 靈芝를 栽培한 結果는 다음과 같다. 種菌接種短木에 菌接種時期가 1月, 12月, 2月, 3月, 4月, 順으로 氣溫이 올라 갈수록 菌絲活着 期間이 빨라져 버섯培養할 때 까지의 菌絲培養 期間을 10日 以上 短縮할 수 있었다. 菌絲培養床의 크기 中 菌絲培養床 幅을 各各 0.8m,1.2m로 하였을 때 같은 菌絲培養期間 동안의 菌絲活着率은 89.6%, 96.4%, 91.2%가 되어 菌絲培養床 幅이 1.0m에서 菌絲活着率이 가장 높았다. 接種短木에 種菌을 接種 後 密封方法은 스치로폴을 막은 後 파라핀으로 密封한 것이 菌絲培養條件에 關係없이 푸른곰팡이 發生率이 가장 낮았고, 스치로폴만 막은것도 新聞紙를 材料로 菌絲培養 條件을 改善하여 푸른곰팡이의 發生率을 파라핀으로 完全히 密封 것과 거의 같은 水準으로 抑制 시킬 수 있었다. 二重 비닐하우스 栽培舍內의 內部 하우스에 遮光幕을 設置함으로서 一般 裁培舍 하우스의 6個月 水準의 靈芝生育 適溫期間을 8個月 以上 까지 延長할 수 있었고, 收穫回數를 年 2回에서 4回로 늘릴 수 있었다. 內部 하우스에 遮光幕을 設置하여 改善한 栽培舍에서는 버섯培養 後 2年次에 目標水準 收穫量의 96.9% 까지 收穫할 수 있었는데 一般 栽培舍에서는 目標 收量의 89.1%만 收穫할 수 있었다. 收穫量에서도 改良 栽培舍의 上品靈芝收量이 一般 載培舍에 比하여 1.5倍의 增收를 보였다. 粘土含量이 가장 많고 모래 含量이 적은 E 土壤에서 雜菌發生이 가장 甚하여 靈芝의 收穫量 및 品質이 가장 低調하였다. To increase the yield and to obtain much better the quality on grown Ganoderma lucidum cultured, these experiments were conducted under carefully controlled in greenhouse with the following conditions on spawn spread related with tentative planting time of short timber inoculated, sealing methods with styrofoam only used and with sealing wax after styrofoam used, soil textures of planting sites, temperatures and growing time as the outside shield was commonly culture method and the inside shield was one of the methods improved itself in these experiments with double vivyl greenhouse. The results were as follow: Speeds of spawn spreading on inoculating Ganoderma lucidum to the short timber were faster when the temperatures were increasing as Jan.<Dec.<Feb.<Mar.<Apr., and it could be short more than 10 days for tentative planting time with inoculation. During the same time of tentative planting the rate of spawn was the highest at the width of 1.0m when the widths of tentative planting hotbets were 0.8, 1.0, and 1.2m, and the rates were 89.6, 96.4, 91.2%, respectively. Occurrences of green mold on inoculated timbers were the lowest as the sealing wax after styrofoam used without the conditions of tentative planting, and when there were surrounding the pile of timbers with styrofoam only used to seal inoculating holes with the second hand newspapers, those were almost the same level as the sealing wax after styrofoam used. When the shield over the roof of the inside greenhouse in the double greenhouse was set, the time on growing could be prolonged until more than 8 months and the yield could be increased 2 times more from 2 to 4 times as compared with the outside shielding over the vinyl that was the common culture method to be known. The culture with inside shielding could improve to be possible that the 96.9% of objective yield was done during two years only and that the amount of the best qualities was 1.5 times than in the common culture, the outside shielding, there was 89.1% of yield only at the same time. In sandy caly that was the least sand and was the most clay of the soils experimented there was the least of yield, there were the plenty of various germs occurred and there was not good in the quality.

The purpose of this study is to investigate the effect of raw Cassia tora L. powder added-diets on reducing cadmium accumulation in rats. The experimental animals were Sprague-Dawley family(♂ , 4 weeks) which was classified into normal group CN, compared group CS, Cd-added group C1 and groups C2, C3. C4 in which 0.5, 1.0 and 1.5% of the Cassia tora L. powder are added, respectively. The growth rate and food efficiency ratio, and the amounts of accumulated cadmium in rats for 8 weeks were measured and analyzed. The results are as follows; 1. The rates of weight gain decreased in the order of C3>C2>C4>Cn>Cs>C1 groups, and C1 group to which only cadmium water had been fed was the lowest among them. The correlation between groups C1 and C3 was significantly different at the 1% level. 2. Food efficiency ratio(FER) decreased in the order of C3>C2>Cs>Cn>C4>C1, and the FERs of C3, C2, CS, CN and C4 are greater than that of C1 by 22.87, 19.89, 18.54, 14.20 and 13.17%, respectively. 3. As fix the Cassia tora L. powder-added groups, the amounts of cadmium accumulated in organs and tissues that is, the brain, heart, spleen, liver, lungs, testicles, kidney, femoral muscle and leg bones were 0.45±0.04 to 0.83±.04, 1.68±0.02 to 2.16±0.02, 3.26±0.05 to 4.62±0.27, 37.82±0.09 to 47.71±0.73, 1.07±0.10 to 1.66±0.04, 1.04±0.06 to 1.24±0.08, 36.79±0.20 to 39.61±0.53, 0.87±0.02 to 1.00±0.02 and 0.65±0.17 to 1.27±0.06 ㎍/g respectively. 4. The accumulated Cd content for C4 was the lowest among Cassia tora L. powder-added groups. When the results for C4 are compared with those for C1, it is observed that each cadmium content accumulated in the brain, heart, spleen, liver, lungs, testicles, kidney, femoral muscle and leg bones is dropped by 49.03, 22.56, 36.02, 35.75, 41.75, 36.20, 37.00, 22.77 and 56.67%, respectively. On the other hand, the accumulated Cd content increased in the order of brain <leg bones <femoral muscle <testicles <lungs <heart <spleen <kidney <liver. 5. The average Cd accumulation rate in organs and tissues relative to the total Cd intake was 7.14% for C1, while they are 4.91, 4.81 and 4.509a for Cassia tora L. powder-added groups C2, C3 and C4, respectively. 6. The Cd content accumulated in the hair for C1 was the highest, and those for Cassia tora L. powder-added groups gradually increased until 6 weeks and decreased after that. 7. The Cd content accumulated in the feces for C4 was the highest, and those for the groups other than C3 and C4 gradually decreased until 6 weeks and increased after that.

백승화,김성조 한국환경농학회 1994 한국환경농학회지 Vol.13 No.2

대기오염에 따른 토양 및 식물체중의 Cd 및 Zn의 함량변화 차이를 구명하기 위하여 대기형 오염물질 방출지역으로 장항제련소 인근지역의 영향을 받는 논토양을 중심으로 1982년도, 1990년도에 표토와 심토로 구분 채취한 토양시료를 그리고 1990년도의 토양 채취지역에서 재배된 수도체 시료 중 Cd 및 Zn 함량을 분석하여 그 변화를 분석하였다. 제련소 인근지역의 토양 중 이들 중금속의 분포는 Cd이 0.09-4.42, Zn이 16.0-959.5㎎ ㎏^(-1)이었으며 평균함량이 1982년도 보다 1990년도에 더 많아지고 있었고 Cd의 경우 년도간에 유의한 상관성이 나타나고 있었다. 배연중심으로부터 동쪽방향이 거리가 멀어짐에 따라 Cd 및 Zn의 함량이 감소하는 변화가 뚜렷하였고, 방향별 토양 중 Cd 및 Zn의 함량은 배연으로부터 동쪽>북북동쪽>북동쪽>북쪽 순으로 작아지고 있었다. 오염반경은 동쪽이 4㎞, 북북동, 북동쪽의 경우는 3㎞로 볼 수 있었고, 표토중 Cd 및 Zn의 함량이 심토보다 많았다, 또한 이 지역의 1982년 토양 중의 Cd 및 Zn의 함량은 이들 금속의 상호간에, 이들 금속과 토양 중 Cu및 Pb함량과 그리고 토양의 유기물함량, 유효인산, CEC, 치환성 Ca^(++) Na^+ 함량과 유의성 있는 상관관계를 나타내었다. 수도체의 경우 부위별 Cd 함량은 현미중의 함량이 가장 낮았으며, 이 양은 엽신 및 엽초중 Cd 함량의 7분의 1의 수준이었고, 엽신, 줄기 및 화서축 중 Cd함량은 토양 중 Zn, Cu, Pb 함량과 유의성 있는 상관관계를 나타내었다. 또한 엽신 중 Zn 함량은 토양 중 Cd, Cu 및 Pb 함량과 유의성 있는 상관관계를 나타내었고, 줄기 중의 Zn 함량은 토양 중 Cu와 Pb 함량과 유의성 있는 상관 관계를 나타냈다. 장항제련소 지역의 현미 중 Cd의 함량은 0.05-0.25㎎ ㎏^(-1), Zn의 함량은 10.5-30.9㎎ ㎏^(-1) 범위였다. To investigate differences in Cd and Zn contents in paddy soils and rice plants polluted by aerial emissions from the Janghang smelter, soil samples in the different directions and at the surface (0-15㎝) and subsurface (15-30㎝) in 1982 and 1990, and rice plants at the corresponding sampling sites in 1990 were collected from the Janghang Smelter Area. Soil samples were extracted with 4M-HNO₃ and plant samples were digested with a mixture of HNO₃ and HClO₄for analyzing by atomic absorption spectrophotometry. The Cd and Zn contents in soils ranged from 0.09 to 4.42 and from 16.0 to 959.5㎎ ㎏^(-1), respectively. The average contents of Cd and Zn in 1990 were higher than those in 1982. The Cd and Zn contents of soils near the center of the smelter were higher than those of soils farther from the center and also decreased in the order of east > north-north east > north east > north. The Cd and Zn levels in surface soils were higher than those in subsurface soils. The contaminated areas of Cd and Zn were within 4㎞ in the east, and within 3㎞ in the north-north east and the north east. Metal contents in brawn rice were the lowest in rice plants. The Cd content of brown rice was one sixth of that in leaf blade and in leaf sheath. The Cd content of leaf blade, stem and panicle axis were significantly correlated with the levels of Zn, Cu and Pb in soils, and Zn content of stem was significantly correlated with the levels of Cu and Pb. The Cd and Zn content in brown rice ranged from 0.05 to 0.25㎎ ㎏^(-1) and from 10.5 to 30.9㎎ ㎏^(-1) in the smelter area, respectively.

백승화,류택규,이만상,김성조,양창휴,문광현 한국환경농학회 1994 한국환경농학회지 Vol.13 No.1

대기오염에 따른 Cu의 함량변화 차이를 구명하기 위하여 대기형 오염물질 방출지역으로 장항제련소 인근지역의 논 토양을 중심으로 1982년도에 표·심토로 구분 채취한 것과 1990년도에 채취한 토양시료, 그리고 1990년에 토양시료 채취지역에서 재배된 수도체 중의 Cu 함량을 분석하여 그 변화 요인을 추적 분석하였다. 제련소 인근지역의 토양 중 Cu함량은 5.1-391.0 ㎎ ㎏^(-1)였고, 평균함량이 1990년 토양이 1982년도 토양 보다 높았으며, 1982년도 표토 중 Cu함량은 1990년도 표·심토 간 Cu함량과 유의성 있는 상관을 나타냈다. 배연의 중심으로부터 동쪽방향에서 거리별 Cu함량변화가 뚜렷하였고, 그 정도는 동쪽>북북동=북동>북쪽 순으로 작아졌다. 배연에 의한 오염반경은 동쪽 5㎞, 북북동과 북동이 3㎞였으며, 1982년도 토양 중 Cu함량은 유효인산, 유효규산, 치환성 Ca^(++)과 Na^(+) 양과 유의한 상관성을 나타내었다. 이 지역 수도체의 엽초, 줄기, 현미중 Cu함량은 토양 중 Cd, Zn, Cu 및 Pb함량과 유의성 있는 상관관계를 나타내었고, 현미 중의 Cu 함량은 0.4-3.6 ㎎ ㎏^(-1) 이었으며 수도체의 부위에 따라서는 현미 중 Cu 함량의 13.75배까지 축적되는 경우도 있었다. 대기오염에 의한 토양 중 Cu 함량은 토양 중 Zn 및 Pb함량과도 유의한 상관관계를 나타내고 있어서 이들 금속들이 오염물질로서 함께 유입되고 있음을 나타냈다. To investigate differences in Cu contents in paddy soils and rices, being affected by air pollutants from the Janghang Smelter, soil samples at the different directions and surface (0-15㎝) and subsurface (15-30㎝) were collected in 1982 and 1990, and rice plants at the soil corresponding sampling sites in 1990 were also at separately collected from the Janghang Smelter area. Soil samples were extracted with 4M-HNO₃and plant samples were digested with a mixture of HNO₃and HClO₃for analyzing Cu, Zn, Cd and Pb by atomic absorption spectrophotometry. The Cu contents in soils ranged from 5.1 to 391.0 ㎎ ㎏^(-1). The average content of Cu in 1990 was higher than that in 1982. The Cu content in soils nearer to the center of the smelter was higher than that farther from the center. The Cu content was highest at the east direction, and was in order of east > north-north east = north east > north. The variation of Cu levels in soil at east sites was more considerable than other directions. The Cu level in surface soils was higher than that in subsurface soils. The Cu contaminated area was within 5 ㎞ at east, and 3 ㎞ at north-north east and north east. A significant correlation was found between Cu content in surface soils of 1982 and that in surface and subsurface soils of 1990, and between Cu content in soils and soil properties such as organic matter(OM), available phosphate, available silicate, exchangeable Ca^(++) and Na^(+) in 1982. The Cu content in brown rice ranged from 0.4 to 3.6 ㎎ ㎏^(-1), and was the lowest in parts of rice plant, and Cu content in a part of plant was 13.75 times higher than that in brown rice. The Cu content of leaf sheath, stem and brown rice was correlated with the levels of Cd, Zn, Cu and Pb in soils. The Cu content in soil regardless of years and soil depths was correlated with Zn and Pb in soil in the area affected by waste gas.
