Methods of isolation and determination of volatile organohalogen compounds in natural and treated waters

Volatile organohalogen environmental pollutants and their sources and the routes of entry into various elements of the environment are described. Comprehensive literature data on the concentrations of these pollutants in natural and treated waters and in wastewaters in various countries are tabulated and discussed. A wide selection of the techniques for the isolation and preconcentration of the above pollutants are presented and discussed. Direct aqueous injection into a capillary column, liquid-liquid extraction, solid-phase extraction and headspace analysis are emphasized.
