title: Gas chromatography-mass spectrometry with headspace for the analysis of volatile organic compounds in waste water.
abstract: Headspace analysis combined with high-resolution gas chromatography and detection by mass spectrometry was evaluated for the analysis of 53 volatile organic compounds (VOCs) in river waters, waste waters and treated water samples down to 0.1 microgl(-1) concentration levels. The conditions optimised included sample thermostatting time and temperature, autosampler parameters and the nature of salt, added to the sample. The pollutions origin and their seasonal rippling have been done. It was shown that the content of VOCs in river water mainly correlates to the content of these compounds in waste waters, which shows the anthropogenic character of the pollutions.
