This study was performed to investigate the present contamination level of heavy metals in freshwater fishes in North Han-river Contents of heavy metal in the parts were found respectively by the Atomic Absorption Spectrophotometer. The results were shown as follows: 1. The order of mean value of lead, cadmium and chromium contents in the three parts was shown as bone>gill>muscle respectively. Content of mercury in muscle showed highest in comparison with the other parts. 2. Among the seven heavy metal contents, the highest was zinc and the lowest was cadmium. 3. Among the three kinds of fishes Cyprinus carpio has highly significant correlation with fish size in lead and cadmium.

This study was conducted to measure the diurnal variation and behaviour of atmospheric mercury in an urban area by gold amalgamation and c이d vapour atomic absorption spectrophotometry. The results were as follows: 1. The Hg concentration in ambient air averageq 21.13ngjm3 for 111 determinations (C.V. 78.5) in urban area and 5.91ngjm3 for 140 determinations (C.V. 2 1.3) in suburban area. The urban area concentration was significant1y higher and f1uctuated more than its rural counterpart. 2. Regression analysis of the interaction between mercury concentration and other components showed a significant correlation between mercury concentration and sulfur dioxide; also, TSP were found. Mercury concentration was shown to have a similar behaviour, on the whole, with other air pollutants. 3. It demonstrated a positive correlation with sun1ight (UV-ray), while it had a negative response to wind speed and humidity. Its concentration showed a tendensy to increase during calm weather specifical1y. 4. The Hg concentration at the Mt. DδkYou inland clean area ranged from 1.33ngjm3 to 2.0ngjm3 , with a mean value of 1.63ngjm3
