%X The volatile CHCl3, CCl4, CHBrCl2, CHBr2Cl, CHBr3 in drinking water have been determined by wide bore capillary gas chromatography/electron capture detector(GC/ECD) with direct aqueous injection method. The method is simple, fast and highly sensitive. It has better accuracy and precision. When the average mass concentration of five halohydrocarbons ranged from 9.03 to 20.19 micrograms/L, the relative deviations ranged from 5.7% to 9.1%, RSD ranged from 2.9% to 7.5%. The standard deviations ranged from 0.3 to 0.9. Correlation coefficients were 0.998 and 0.999. The detection limits ranged from 0.1 to 0.7 microgram/L and were lower than those in other work when the temperature of ECD was 350 degrees C.
