  • The purpose of this study is to compare the contents of heavy metals of boiled ssangwhatang with those of herbal ingredients which are composed of ssangwhatang. Ssangwhatang is used for antifatigue, tonic and so on. With industrial development, our environment has been very polluted. Herbal medicines also are seriously contaminated by heavy metals and pesticides. The herbal medicines of ssangwhatang were bought at 10 defferent markets. The contents of 14 heavy metals(Ag, As, Ba, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Sb, Sn, Zn) were analysed using ICP. It was found out that 7 heavy metals(Pb, As, Ba, Cd, Hg, Sb, Sn) were not detected at all in boiled ssangwhatangs. But they were detectable in all ssangwhatangingredients before boiling. For example, the content of Pb in one pack of ssangwhatang before boiling was $0.039^{\circ}{\pm}0.005mg$ and Pb in boiled one was not detected. Herbal medicine itself is seriously contaminated by heavy metals. These results suggest that boiled ssangwhatang which we take is safe from the contamination of heavy metals.

  • The contents of heavy metals in boiled Sibjeonaebotang with those in its herbal ingredients are compared. The herbal medicines of Sibjeonaebotang were bought at 10 defferent markets. The contents of 14 heavy metals (Ag, As, Ba, Cd, Cr Cu, Fe, Hg, Mn, Ni, Pb, Sb, Sn, Zn) were analysed using ICP It was found out that 5 heavy metals (Pb, As, Ba, Fe, Sb) were detected in only one boiled Sibjeonaebotang But they were detectable in all Sibjeonaebotang and its herbal before boiling. For example the content of Hg in one pack of Sibjeonaebotang before boiling was 0.064$\pm$0.016 me and Hg in boiled one was 0.002$\pm$0.005mg. These results suggest that boiled Sibjeonaebotang which we take is less harmful than herbal medicine itself by heavy metals.

  • Objectives: This study was conducted to evaluate the total heavy metals contents and chemical forms in the animal manure compost. Materials and methods: A total of 109 compost samples were collected throughout the country and classified into three groups in accordance with the raw materials; pig manure, poultry manure and mixed(pig+poultry+cattle) manure. The compost samples were analyzed for total metal content and sequential chemical extraction to estimate the quantities of metals. Results: Concentrations of Zn and Cu in several compost samples were higher than the maximum acceptable limits by the Korea Compost Quality Standards. Concentrations of Zn, Cu, and Cd in compost samples were 257~5,102, 68~1,243, and 0.02~2.54 mg/kg respectively, while Cr, Ni, As, and Pb were < 20 mg/kg. The concentrations of heavy metals in pig manure compost were higher than those of both the poultry and the mixed manure compost. The predominant forms for extracted metals were Cr, Ni, Zn, As, and Pb, residual; Cu, organic; and Cd, carbonate. Conclusions: Results indicate that the Zn and Cu contents in compost were higher than other heavy metals and the heavy metal contents were greater in pig manure compost followed by mixed and poultry manure compost. To prevent the accumulation of heavy metals in soil where animal manure compost is applied, strategy for reducing heavy metal concentrations in animal manure and compost must be considered.

  • The study was conducted to measure the heavy metal pollution of soils at the playground for children and to investigate the characteristics of heavy metals distribution I city. The studied area was divided into two: the residential area and the industrial area. The samples of the sands and soils were collected from both areas. The results were obtained as follows. All average concentration of 6 different heavy metals was found to be lower than the standard of soil pollution. Zn, Pb and cu concentrations were higher than other species of heavy metals. The contents of heavy metals in the soil were higher than the sands. The average contents of Zn, Pb, Cu, As, Hg and Cd in soil were 38.36, 9.53, 7.31, 0.03, 0.18 and 0.09 mg/kg respectively. Comparing with the residential area, heavy metal concentrations of the industrial area were 4.60, 1.49, 2.60 and 4.29 times for Zn, Pb, Hg and Cd in soils, respectively.

  • determine the distribution of heavy metals in estuarine sediments, forty surface sediment samples were collected from the Youngsan estuary, and analysed for their contents of Fe, Mn, Co, Cr, Cu, Ni, Zn and Pb. Contents of most analysed metals were comparable to those in the near shore environment around Korean peninsula, and little anthropogenic effect was identified. However, there was a contrasting behavior among the metals with respect to their relationship with the grain-size of sediments. Contents of Fe, Co, Cr and Ni demonstrated a fairly linear relationship with the grain-size of sediments whereas those of Mn, Cu, Zn and Pb did not. This different behavior In these metals was Interpreted as being the result of the additional inputs. The R-mode factor analysis also confirmed the different behavior of Cu, Zn, Pb and Mn from that of Fe, Co, Cr and Ni.

  • 전라북도 군산시 연안에 위치한 공업단지의 여러 제조업체에서 배출되는 매연, 분진의 영향으로 토양오염이 우려되는 지점을 선정하여 논 토양과 현미 중 중금속함량 및 오염원들과 현미 중 중금속함량간의 상관관계를 조사하였다. 공업단지 인근 지역 논 토양 중 전중금속 평균함량은 Pb 34.33, Cd 0.50, Cu 35.49, Zn 71.67 mg/kg이었으며 제조업체별, 거리별 논 토양 중금속의 분포상태를 조사한 결과 제조업체별, 거리별로 중금속함량이 일정한 경향을 보이지 않았다. 현미 중 중금속 함량은 Pb 1.74, Cd 0.07, Cu 3.54, Zn 16.53 mg/kg이었다. 군산 공업단지 인근 논 토양중 0.1N-HCl 가용성 중금속함량과 현미 중 중금속함량과의 상관관계를 보면 Pb가 1% 유의수준에서 정의 상관율$(r=0.6853^{**})$, Zn이 5% 유의수준에서 정의 상관$(r=0.5420^*)$을 보였으며, 토양 중 전 중금속함량과 수도체 현미 중 중금속함량과의 상관관계를 보면 Pb만이 1% 유의수준에서 정의 상관$(r=0.7131^{**})$을 보였다. 군산 공업단지 인근 논토양과 현미 중 중금속 함량은 공업단지에서 배출되는 매연이나 분진 중에 함유되어 있는 중금속 오염물질의 영향을 받아 부분적으로 오염이 진행되고 있으나 아직 오염을 우려할 수준에까지 이르지는 않았다.

  • This study was performed to investigated the contamination levels of harmful heavy metals were sampled from Aug. 1 to Aug. 31, 1997, at 9 areas in Cheonbuk area. The heavy metal contents were determinated by ICPS(Inductively Coupled Plasma Spectrometer) method. The levels of total lead, cadmium, aluminum, iron and copper were determined and the results were summarized as follows: The minimum and maximum values(ppm) of 9 areas of Carassius auratus were Pb: 2.03~6.19, Cd: 0.06~ 0.76, Al: 8.84~23.5, Zn: 10.68~48.71, Cu: 0.60~1.51ppm. Among the five heavy metals contents, the highest was zinc and the lowest was cadmium. The results showed that the contents of Pb, Cd, Al, Zn and Cu in Carassius auratus were lower than the FAO/WHO maximum allowance.

  • 서울시내에 유통 중인 대형어류 17종 89건에 대하여 원자흡광광도계(AAS) 및 수은분석기 등을 이용하여 납, 카드뮴, 수은, 크롬, 구리, 비소 함량을 근육, 간 및 아가미 등의 부위별로 분석하였다. 그 결과를 요약하면 다음과 같다($Mean{\pm}SD$, mg/kg). 어종별 평균 중금속 함량은 Hg $0.08{\pm}0.01mg/kg$, Pb $0.17{\pm}0.32mg/kg$, Cd $0.34{\pm}0.07mg/kg$, Cr $0.05{\pm}0.05mg/kg$, Cu $1.14{\pm}0.13mg/kg$, As $0.24{\pm}0.22mg/kg$ 이었다. 부위별 유해 중금속의 전체적인 측정치를 살펴보면 중금속과 어종에 상관없이 간의 측정치가 가장 높게 나타났다. 나라별 중금속을 비교한 결과 Hg, Pb, Cu는 뉴질랜드산, Cd, As는 노르웨이산, Cr은 국내산 어류의 평균함유량이 다른 나라 어류보다 다소 높은 측정치를 보였으나, 자연함량수준으로 오염의 가능성은 없다고 생각된다. 기준초과로 검출된 어종은 일본에서 수입된 황돔으로 두 건이었다. 어류의 간과 근육 부위 중금속 함량 간의 상관관계는 Hg (r=0.989, p<0.01), Pb (r=0.978, p<0.01), Cd (r=0.991, p<0.01), Cu (r=0.998, p<0.01), As (r=0.198, p<0.05)에서 상관관계를 나타냈으며, Cr (r=0.082)은 유의적 상관관계가 인정되지 않았다.

  • Atmospheric particulate matter (A.P.M.) was collected on quartz fiber filters from March 1985 to May 1986 according to particle size using Andersen high-volume air sampler, and 6 heavy metals (Fe, Mn, Cu, Ni, Zn, Pb) in these particulates were analyzed by atomic absorption spectrophotometry. The arithmetic mean concentration of A.P.M. was 195.57$\mug/m^3$. The arithmetic mean concentrations of 6 metals (Fe, Mn, Cu, Ni, Zn and Pb) were 3385.04, 1451.67, 897.94, 159.68, 127.14 and 59.49 $ng/m^3$ respectively. The order of heavy metals contributing to A.P.M. was as follows: Fe > Zn > Pb > Cu > Mn > Ni. These heavy metals were devided into 3 groups according to their particle size distribution. The contents of heavy metals belonging to the 1st group (Fe, Mn) were increased with the particle size. On the contrary, the content of Pb belonging to the 2nd group (Pb) was increased with the decrease in the particle size. The heavy metal contents in the 3rd group (Ni, Cu, Zn) were lowest in the particle size range of 2.0-3.3 $\mum$ compared with particles larger or smaller tha this range. The seasonal variation of heavy metal concentration were as follows: Fe and Mn contents were highest in spring, but Ni and Pb contents were highest in winter. Statistical analysis showed that there was a significant correlation between A.P.M. and Fe in coarse particles, meanwhile between A.P.M. and Pb in the case of fine particles.
