dc.description.abstractThis study investigated the feasibility of applying solid-phase microextraction (SPME) combined with gas chromatography-mass spectrometry to analyze chlorophenols in urine. The SPME experimental procedures to extract chlorophenols in urine were optimized with a polar polyacrylate coated fiber at pH 1, extraction time for 50 min and desorption in GC injector at 290 degrees C for 2 min. The linearity was obtained with a precision below 10% R.S.D. for the studied chlorophenols in a wide range from 0.1 to 100 mu g/l. In addition, sample extraction by SPME was used to estimate the detection limits of chlorophenols in urine, with selected ion monitoring of GC-RIS operated in the electron impact mode and negative chemical ionization mode. Detection limits were obtained at the low ng/l levels. The application of the methods to the determination of chlorophenols in real samples was tested by analyzing urine samples of sawmill workers. The chlorophenols were found in workers, the urinary concentration ranging from 0.02 mu g/l (PCP) to 1.56 mu g/l (2,4-DCP) depending on chlorophenols. The results show that trace chlorophenols have been detected with SPME-GC-MS in the workers of sawmill where chlorophenol-containing anti-stain agents had been previously used.
