Rapid gas-chromatographic determination of trichloroethylene and/or tetrachloroethylene in lettuce by direct head-space analysis.
A direct head-space method has been developed for the rapid investigation of the contamination of large numbers of individual lettuce plants as a consequence of local ground water and soil pollution with trichloroethylene and/or tetrachloroethylene. The plants were divided into several anatomically and physiologically distinct parts with different chemico-physical properties.
