| Abstract |
From 17 tap water sampling points throughout the metropolitan Seoul supplied from paldang, Gueui, Bokwang, Noryang jin and Dukdo water treatment plant, using Han river as water source, trihalomethane concentration were measured 3 times during July, August, and September, 1984. Total trihalomethane were high in tap water samples from Noryang jin and Dukdo water treatment plant and low from Gueui water treatment plant. Average trihalomethane concentrations were 32.2㎍/ℓ, 19.1㎍/ℓand 9.8㎍/ℓfor July, August, and September respectively, and by comparing with the trihalomethane concentrations of August and September, that of July was obviously high. It is noted that average CHCl₂Br concentration of tap water supplied from Noryang jin water treatment plant in July was 12.9 ㎍/ℓ which were attained to about twice of total average concentration of 6.5㎍/ℓ. |
