Several phenolic compounds are present in tobaccosmoke. They are formed from the pyrolysis of tobaccoduring the smoking process and all of them aretoxic. Therefore, the determination of these compounds in air samples is important. A rapid, simple, and sensitive method using a synchronous spectrofluorimetry technique was developed to quantify hydroquinone and resorcinol simultaneously. One of the advantages of this method is the simple and rapid sampling technique, which uses water as the absorption solution of the analytes in the air sample. The precision of the method (%RSD) was 1.8% and the detection limits were 0.125 mgm?3 and 0.292 mgm?3 for hydroquinone and resorcinol, respectively.
