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 Łódź (Lodz), Warszawa (Warsaw), Poznań and Wrocław. 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 Łódź (winter) and tetrachlorophenol in water of Wrocław (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.

Investigations were undertaken in the north-west part of the Tucholski Landscape Park (northern Poland). Samples were collected from soil adjacent to the banks of Lakes Suszek, Śpierewnik, Grochowskie, Raciąż and Stobno. The compounds were adsorbed by the solid-phase extraction method on octadecyl (C 18) layers, separated by thin-layer chromatography (TLC) and gas chromatography (GC) methods and analysed by the densitometry and mass spectrometry (MS) techniques respectively. In samples, phenol, 4-methylphenol, 4-nitrophenol, chlorophenols, chlorocatechols, chloroguaiacols, chlorosyringols, 3,4,5-trichloroveratrole, 5,6-dichlorovaniline and several monoterpenes were determined. The increase of the number and concentrations of the compounds investigated in summer and spring was stated.
