초록

For the survey of water pollution, several heavy metals were analyzed in the sediment of the Han River from March 20 to April 22, 1989. The results were as follows : 1. The respective ranges of heavy metal concentrations of Cadimium, Lead, Copper, Zinc and Manganese found in the sediments of the Han River were 0.32!2.41 $\mu g/g$, 15.80~129.64 $\mu g/g$, 13.82~372.36 $\mu g/g$, 58.40~925.40 $\mu g/g$, 271.50~668.30 $\mu g/g$. 2. In the sediment of inflow site Jung Rang Chon the contents of Lead, Copper, Zinc were the highest among other sampling points and An Yang Chon, the contents of Cadmium, was the highest among other sampling points and Wang Sook Chon, the contents of Manganese, was the highest among other sampling points. 3. Through all sampling points general trend of heavy metal contamination showed the highest in Zinc, the next Manganese, Copper, Lead and Cadmium respectively. 4. The higher amount of heavy metal was found in the finer particles of sediment. 5. The amount of Cadmium and Lead of the Han River water was below the standard of environment.
