| The heavy metal concentrations of seawater collected from the Onsan coastal zone in February and July 1996 and mussels(Mytilus edulis) in February 1997 were analysed. The concentrations of cadmium in seawater were in the range of 0.008-2.988 ${mu}g/L$, while the ranges of copper and zinc concentrations were 0.08-2.55, and 0.21-35.12 ${mu}g/L$, respectively. The metal concentrations decreased gradually with increasing distances from Daejeong stream, indicating that this stream was the major source of heavy metal input into the Onsan coastal zone. The concentrations of cadmium, copper and zinc in mussels were in the ranges of 1.40-25.09, 8.5-64.5, and 46.8-291.2 ${mu}g/g$, respectively. The metal concentrations decreased gradually with increasing distances from Daejeong stream. Among organs of mussels, gill showed the highest concentrations of cadmium and the digestive gland showed the highest concentrations of copper and for zine the kidney showed the highest concentrations. The digestive gland and kidney revealed high proportion of cadmium in cytosolic fraction and the percentage of copper was high in the kidney and that of zine was high in the digestive gland. Metal-binding protein of mussels collected from the mouth of Daejeong stream was separated, using gel-filtration chromatography. In the kidney and gill of mussels, most of cadmium was associated with metal-binding protein. In contrast, most of the metal in the digestive gland and remaining tissues is bound to high molecular weight protein rather than metal-binding protein. |
