CHBrI2, CHI3) and other trihalomethanes in drinking water collected from various places of Japan were measured. Standard iodine trihalomethanes were synthesized in water containing acetaldehyde, Ki, KBr and NaCIO. The products were extracted with dichlorometane, and the solution was calibrated using GC/AED. Iodine trihalomethanes in drinking water were extracted with toluene and analyzed using BC/MS SIM detection. Other trihalomethanes were analyzed using SPME ( solid-phase microectraction) and GC/ECD detection. The detection range (μg/l) of trihalomethanes in 53 drinking water samples were as follows. CHCl. (1.8-155), CHBrCl2 (0.6-90), CHBr2Cl (0.8-290), CHBr3 (0.02-210), CHCl2I (nd-3.3), CHBrClI (nd-3.0), CHBr2I (nd -1.1) , CHCII2 (nd-0.24), CHBrI2 (nd-0.07), CHI3 (nd-0.05). Limits of detection of iodine trihalomethanes were 0.01μg/l.}, pages = {11--16}, title = {水道水中のヨウ素系トリハロメタンの測定}, volume = {22}, year = {1996} }
