Abstract

Some triazines and metabolities have been analyzed in water and soil samples, at the 0.1 and 10 ppb level, respectively, by CGCโ€MS and CGCโ€MSโ€MS using an ion trap detector (ITD). The sample preparation consisted of SPE on LiChrolut EN cartridges for water samples, and of ultrasonic treatment followed by SPE for soil samples. Recoveries were in the order of 90%. The advantage of MSโ€MS compared to MS operation of the ITD, is the enhanced selectivity resulting in more precise determinations. The metabolites of atrazine and metribuzin have also been studied. Desethylatrazine and desaminoโ€metribuzin are the main metabolites.
