Abstract: Most solid-phase microextraction methods are based on poly (dimethylsiloxane)-coated silica fibers. Is the present study, pencil lead was used as an alternative sorbent for solid-phase imcroextraction. Its application to three organic pollutants with different polarity in water was investigated. The detection limit for determination by gas chromatography with electron capture detector was 0.005 ng ml-1 for lindane, 0.05 ng ml-1 for methyl parathion and 1 ng ml-1 for 2-chlorophenol. The presence of dissolved humic substances (10 mg l-1) in water did not affect the extraction of the three analytes. © 1994.
