Abstract

|
|
SPME deuce was applied to determine the THM in an aqueous solution. The 6 kinds of THM was quantitatively detenuned by using GC-ECD which has the sample eutracted on the SPME fiber from an aqueous solution for 10 min. The THM components were well separated from to the last UHh 13 mons at the condition. 6 kinds of the volatile halogenated organic compounds: , , , . and , showed well defirled calibration graph with good llnearlty from a few ppb level up to several tens of pub concentration. and were detected from a few samples among the 10 of river samples. CHCl3, however, was detected In 4 sea water samples with the highest of 10 ppd among the pouuted 6 positions. Trace level of and few pub level of were also detected at the other two sample stations. Most of the 13 rain water samples collected from 6 sampling stations were contained ppd level of , and also , and were only detected at trace level at a few rain samples among them. We could recognize the fact that our Ut and water enoronment has already been contaminated by certain volatile halogenated organic compounds through this study.
