Trihalogenmetanes (THM) are produced during water treatment when available chlorine from dissinfection reacts with organic matrices. The frequently formed compounds are chloroform, bromdichlormetane, dibromchlormetane and bromoform. The concentrations of THM in drinking water have been determined in 47 samples by applying high resolution gas chromatography equiped with NB-1701 and NB-54 columns and also with two ECD's. Identification of THM is based on retention indices present in the computer library. Concentrations of THM in 47 samples of drinking water ranged from 0.5-1 microg/l in 6% of samples, 1-10 microg/l in 28% of samples, 10-100 microg/l in 16% of samples, less than 0.5 microg/l - in 50% of samples.
