Bioaccumulation of Trace Metals by Mussel (Mytilus edulis) from Korean Coast
이인숙,송준임,박경숙,최병래,노분조,Lee, I.S.,Song, J.I.,Park, K.S.,Choe, B.L.,Rho, B.J. The Ecological Society of Korea 1995 Journal of Ecology and Environment Vol.18 No.3
This study was carried out to investigate the concentrations of Cu, Pb, Zn and in seawater, sediments and Mytilus edulis at Masan Bay, Onsan Bay, Daesan industrial complex and unpolluted area for the degree of contamination on the coast of Korea. The concentrations of dissolved Cu, Pb, Zn and Cd in seawater the ranges of 0.29~0.79 ${\mu}g/l$, 0.03~0.08 ${\mu}g/l$, 0.19~2.01 ${\mu}g/l$ and 0.01~0.05 ${\mu}g/l$, respectively. The concentrations of Pb(p<0.001) and Zn(p<0.01) showed the significant differences between the contaminated and unpolluted area. There were the ranges of 13~55 ${\mu}g/l$, 26~101 ${\mu}g/l$, 51~263 ${\mu}g/l$ and 0.8~2.2 ${\mu}g/l$ in the concentration of Cu, Pb, Zn and contaminated and unpolluted area. The concentration of Cu, Pb, Zn and Cd in the Mytilus edulis showed the ranges of 0.69~2.77 ${\mu}g/l$, 0.29~1.50 ${\mu}g/l$, 13.57~52.90 ${\mu}g/l$ and 0.09~0.85 ${\mu}g/l$ respectively. These concentrations of four trace metal in Mytilus edulis were not significantly different with sites. Trace metal contents of Mytilus edulis in the contaminated site were similar to those in the unpolluted area. This is thought that metal concentration in coastal seawater were not relatively serious.

Yellow loess, Tidal plat sediment, and mud are known to be high in adsorption though they have great distinction according to the ratio of clay minerals content and their kinds. Thus one of the samples for this study can be obtained by drying of Yellow loess, Tidal plat sediment, and the mud which is semifinished products that are from the progress of heat treatment and making homogeneity which can be found everywhere in our country. Another sample can be prepared by reducing pollutants with the adsorbent and by burning heavy metals of their own. With the samples, noxious heavy metals such as Pb, Cd, and essential trace elements such as Cu, Fe, Mn by each concentration is tested for adsorption according to pH, the kinds of adsorbents and the amount of injection. With the help of these steps, this study shows that the adsorbents, which are green, reducing the additional pollution and low in price, can be found. It also shows that the optimal condition for removing pollutants can be found and the basic materials for treating water can be offered. The results were as follows;<br/> Yellow loess shows the rates of adsorption by more than 50% and Tidal plat sediment and Mud show it by more than 90%. Thus Tidal plat sediment and Mud are higher than Yellow loess the rates of adsorption.<br/> The pH should be treated in natural condition because the rates of adsorption of Pb, Cd, Cu, Mn excepting Fe in mud is higher in pH 7 than in pH 3 of Yellow loess, Tidal plat sediment, and Mud.<br/> The drying adsorbents are good to use because the rates of adsorption of heavy metals has tendency to be higher in the drying method than in the burning method.<br/> It is considered that the more the amount of the injection of the adsorbent is , the higher the rates of adsorption is, and one gram is reasonable for the amount of the injection of Tidal plat sediment and mud.<br/> Yellow loess is suitable for the treatment of the water that includes low concentration of heavy metals because it has the lower rate of adsorption as the concentration of noxious heavy metals is higher.<br/> It is thought that Tidal plat sediment and Mud is proper for the treatment of the water that includes high concentration of heavy metals because the rates of adsorption has not been changed as the concentration of heavy metals increases.

한국 연안에서 Mussel(Mytilus edulis)의 중금속의 생물 농축
이인숙,송준임,박경숙,최병래,노분조 이화여자대학교 생명과학연구소 1995 생명과학연구논문집 Vol.6 No.-
본 연구는 남한 연안의 오염도를 파악하기 위해 마산만, 온산만, 대산공업 단지 및 비오염구에서 해수, 퇴적물 및 진주담치의 구리, 납, 아연 및 카드뮴의 농도를 조사하였다. 해수의 용존성 구리, 납, 아연 및 카드뮴의 농두는 각각 0.29~0.79 ㎍/l, 0.03~0.08 ㎍/l, 0.19~2.01 ㎍/l, 0.01~0.05 ㎍/l 범위를 나타냈으며, 납(p<0.001)과 아연 농도(p<0.01)는 오염구와 비오염구 간에 유의적인 차이가 있었다, 퇴적물의 구리, 납, 아연 및 카드뮴의 농도는 13~55 ㎍/g, 26~101 ㎍/g, 51~263 ㎍/g, 0.8~2.2 ㎍/g 범위를 모였으며, 오염구와 비오염구 사이에 카드뮴 농도는 유의적인 차이를 나타냈다(p<0.05). 진주담치의 구리, 납, 아연 및 카드뮴 농도는 0.69~2.27 ㎍/g, 0.29~1.50 ㎍/g, 13.57~52.90 ㎍/g, 0.09~0.85 ㎍/g 범위로 나타났고, 각 중금속 농도가 오염구와 비오염구 사이에 유의적인 차이를 보이지 않았다. 본 연구에서 오염구에 있는 진주담치의 중금속 농도는 자연 상태인 비오염구에서의 농도와 유사한 값으로 이는 연안 해수가 중금속에 의해 크게 오염되지 않은 것으로 사료된다.

The concentrations of dissolved Cu, Pb, Zn and Cd in seawater showed the ranges of 0.29~0.79 ㎍/l, 0.03~0.08 ㎍/l, 0.19~2.01 ㎍/l, 0.01~0.05 ㎍/l, respectively. The concentrations of Pb(p<0.001) and Zn(p<0.01) showed the significant difference between the concentrations of unpolluted area. There were the ranges of 13~55 ㎍/g, 26~101 ㎍/g, 51~263 ㎍/g and 0.8~2.2 ㎍/g in the concentration of Cu, Pb, Zn and Cd of sediments. The concentrations of Cu were significantly different between the contaminated and unpolluted area. The concentration of Cu, Pb, Zn and Cd, in the Mythilus edulis showed the ranges of 0.69~2.27 ㎍/g, 0.29~1.50 ㎍/g, 13.57~52.90 ㎍/g and 0.09~0.85 ㎍/g respectively. These concentrations of trace metal in Mytilus edulis were not significantly different with sites. Trace metal contents of Mytilus edulis in the contaminated site were similar th those in the unpolluted area. This is thought that metal concentration in coastal seawater were not relatively serious.
