Abstract: The purpose of this work was to determine the occurrence of phenol, chlorophenols, chlorocatechols and chlorinated methoxyphenols in the drinking water of the Polish cities of £ód¼ (Lodz), Warszawa (Warsaw), Poznań and Wroc³aw. The compounds were adsorbed on octadecyl (C18) layer in a Baker-Separex system and eluted with methylene chloride, then analyzed using the methods of gas chromatography and mass spectrometry. In samples, chlorophenols, 4-chlorocatechol, chloroguaiacols, chlorosyringols and 5,6-dichlorovaniline were detected. Higher concentrations and number of chlorophenols and their chlorinated derivatives were noted in summer. Among the most toxic compounds, 2,4,5-trichlorophenol in drinking water of Warszawa (summer and winter) and £ód¼ (winter) and tetrachlorophenol in water of Wroc³aw (summer) were noted. Their concentrations were above the admissible standards of the EU and the US EPA. In some cases the concentrations of chloroguaiacols and 5,6-dichlorovanillin also were significant.
