Solid phase microextraction coupled to gas chromatography-mass spectrometry (SPME-GC-MS) was used determine the adsorption coefficients (Koc) for six target triazines in soil and sediment samples with different organic matter contents textures. SPME-GC-MS conjunction a conventional batch equilibrium method. The recoveries of selected from soils sediments having carbon range 0.2–2.4% were satisfactory. Drawbacks analytical techniques are avoided; owing selectivity SPME-GC-MS, no sample pre-treatment or solvent enrichment steps required so that Koc values could be easily determined. Moreover, sensitivity technique makes it possible work at low triazine concentrations (50–500 ng g–1) where Freundlich isotherm can considered linear.
