This study dealt with the concentration of heavy metals in mussels, Mylitus edulis and oysters, Crassostrea gigas, in different habitats around the Korean coastal waters during 1985-1989. The high levels of heavy metal concentration in two bivalves were found at Station 1, 2, 5, 23 and 25, while the low levels were found at stations in Chinhae Bay. Oysters were more effective bioaccumulators of Cu, Zn and Hg than mussels showing the ratios of 16:1 for Cu, 1.63:1 for Cd, 1.36:1 for Pb, 7.61:1 for Zn and 2.08:1 for Hg. The larger mussels were, the higher the concentrations of five metals.

영산강 수계의 습지생태계 모니터링의 일환으로 4개 지역을 선정하여 황소개구리 205개체를 채집하여 이들의 외부기형 출현율 및 양상을 조사하고 그들의 체내 조직에 축적된 중금속 농도를 분석하였다. 황소개구리의 기형 출현율은 6.8%로 다른 척추동물에서의 자연발생률 3%보다 높았으며, 기형은 모두 앞 또는 뒷발갉에서 나타났다. 유형별로 보면 결손(Ectrodactyly)이 64.3%로 가장 많았고 다음으로 확장(Dilation)이 28.6%, 절단(Truncation) 7.1%의 순이었다. 정상과 기형 개체간에 중금속의 농도를 조직별로 비교해 본 결과 기형개체의 신장에서 Mn은 4배, Zn 은 1.5배, Cu은 7배, Pb는 8배, Cd는 7배 정도 높았다. 또한 기형 개체에서는 이들 원소의 조직분포 패턴도 변화한 것으로 나타났다. 이러한 결과들로부터 황소개구리는 습지생태계의 모니터링 시료로서 유용하게 이용될 수 있음을 알 수 있었다.

The objectives of this study were to evaluate the extent of heavy metals(As, Pb, Cd, Hg)accumulated in sediments of the Kwangyang Bay, and to investigate bioaccumulation of heavy metals(As, Pb, Cd, Hg) in shellfish(Ruditapes philippinarum) commonly found in the intertidal zone of the Kwangyang Bay. The data was also compared with that of Namhae and Kohung intertidal zones, which were regarded as control stations in this study. Substantial geographical variations in heavy metal concentrations in the sediment samples were found. However, heavy metal concentrations in the sediment collected from the intertidal zones of Yochon(stations I, J) and Myodo(stations G, H) close to Yochon Industrial Area exhibited relatively higher heavy metal concentrations, compared to those from other intertidal zones(stations A, B, C) adjacent to POSCO at Kwangyang Bay. In addition, stations A, B, C showed lower heavy metal concentrations in the sediments than controls(K, L). The annual mean concentrations of the heavy metals in the shellfish from the stations(G, H, I, J) were significantly higher than those from other stations(A, B, C, D, E, F). Nevertheless, heavy metal accumulation in sediments was not reflected in bioaccumulation of heavy metals in shellfish, probably indicating that interactions between the heavy metals in sediment and shellfish might be poor in the current study area, Kwangyang Bay.

A ditch is a facility for managing washed-off runoff from parking lot area. Washed-off runoff inflows into ditches where it is retained for a short period of time. At this point, it is assumed that a ditch is a preliminary unit for runoff treatment. This research carries out the distribution of particle size and chemical compound for sediment in parking lot ditch. This work is important to understand the amount of generated sediment from this area to be able to determine different particle size ranges for treatment. Metal concentrations for sediment according to particle size are analyzed. From the distribution of particle size, the weight ratio with the range of $425-850{\mu}m$ is the highest. Considering its weight ratio, the metal concentration of coarser particles is high, otherwise metal concentration increases as particle size decreases. Metal load of the range is higher and the ratio of total metal load in the case of Cu, Pb, Zn is nearly 30%. Moreover metal concentration associated with particle size depends on particle ratio. To manage non-point source pollution for parking lot area, these results can be used with this ditch unit.

Two hundred seventy-four microorganisms were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains and their microbial diversity was analyzed. The specimens of macrofungi were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains. Eunseong and Dogok in Gyeongsangbuk-do, for selecting the heavy metal-degrading strains. Soil was also collected from same location. Contents of heavy metals (Cd, Cu, Pb, Zn, Ni, Cr, and As) were determined spectrometically in fruiting bodies of forty eight wild macrofungi specimens with soils. When the analysed their transfer factor from soil to fruiting body, Amanita volvata have the highest transfer factor of cadmium and arsenic. And Mycena pura showed the highest in mercury, Marasmius pulcherripes in zinc, Laccaria laccata in nickel, and Collybia confluens in chrome. When compare the population of mushrooms between the contaminated mines and Mt. Chiak as the healthy area, Genus Russula and Collybia were collected both area, but Leucocoprinus, Coprinus, Suillus, Lepiost, Gyroporus, Lepista, Microstoma, Stropharia, and Agrocybe were only in the contaminated mine area.
