AB A new analytical methodology based on solvent bar microextraction has been developed to preconcentrate two triazine and two organochloride pesticides in natural waters prior to analysis by gas chromatography. The method was optimized for the organic solvent, sample pH, sample agitation, length of the fiber, extraction time, and salt concentration. The optimized methodology provides high enrichment factors, ranging between 40.2 (aldrin) to 107.0 (lindane). Since no salinity effects were observed, this method may be used to analyze fresh and salt water. Thus, three real samples with different salinities were analyzed with pesticide recoveries higher than 80%. As this methodology agreed with the principles of green analytical chemistry, it offers low solvent and sample consumption, simplicity, and compatibility with current analytical techniques.
