All nine haloacetic acids were completely separated under the optimized gradient elution conditions, and use of selective detection methods or pretreatment with an OnGuard II Ag cartridge resulted in the elimination of interferences from chloride and bromide occurring in soil samples. The procedure for the simultaneous determination of the nine haloacetic acids was simple and rapid. The method detection limits for MFA, DFA, TFA, MCA, DCA, TCA, MBA, DBA, and TBA were 21, 40, 40, 28, 48, 86, 67, 55, and 160 ìg L-1, respectively. Application of this method to the determination of haloacetic acids in real soil samples is illustrated
