Resumo: A method for simultaneous analysis of trihalomethanes and organochloride and pyrethroid pesticides in water utilizing SPME-HS and GC-ECD was developed. In the optimized method 25 mL of water containing 2% (w/v) Na2HPO4 were heated to 60 °C for 50 min. The fiber (PDMS - 100 μm) was exposed to a headspace for the same period. For all analytes it was found that LOQ < MCL (Maximum Contaminant Level), CV < 20% and r > 0.9. The method was applied to potable and surface water samples. Some trihalomethanes were encountered in potable waters, at levels below the MCL.
