ABSTRACT

THMs in disinfection by products are especially important because of their potential
carcinogenity. In this work two different liquid-phase microextraction methods namely
US EPA 551 microextraction method and German DIN 38407 standard method were
compared for the determination of trihalomethanes (THMs) including chloroform
(CHCl3), bromodichloromethane (CHBrCl2), dibromochloromethane (CHBr2Cl) and
bromoform (CHBr3) in water samples was developed, with analysis by gas
chromatographyelectron capture detection (GC-ECD). The USEPA 551 microextraction
method was used in the analyses of water samples for THMs since the recovery ratios
were better for this method in the fortification experiments. Samples were collected
from drinking water distribution network and analyzed for THMs. The order of THM
compounds in abundance in the distribution network could be given as chloroform>
bromodichloromethane> dibromochloromethane> bromoform.
