Volatile organochlorine compounds in the Tiber and Marta rivers have been analyzed by liquid–liquid extraction and headspace gas chromatography. Several different halogenated compounds were identified, in particular chloroform, bromoform, trichloroethane, trichloroethene, and tetrachloroethene. The concentrations of the halocarbons varied between 0.05 and 4.5 μg L –1 with a relative standard deviation ≤4.0%. The highest concentrations were observed for chloroform, bromoform, and tetrachloroethene in the Marta and Tiber rivers. The results obtained by use of the two analytical methods were similar.
