The chemistry of the nitrate radical (NO3.) with a number of volatile organic compounds (VOCs) has been well studied (Atkinson 1994). In the indoor environment these reactions can effectively compete with typical air exchange rates of 0.6 h1 (Wilson et al. 1996). Therefore understanding the fate of these chemicals due to reaction with NO3. is important in determining occupant exposures. These reactions can generate a number of oxygenated products indoors such as: alcohols, aldehydes, ketones, dicarbonyls, carboxylic acids, and organic nitrates all of which have the potential to cause a number of adverse health effects including asthma, allergy and respiratory irritation (Charles et al. 2009; Magnano et al. 2009). The relative rate technique was used to determine the NO3. reaction kinetics of some chemicals found in common indoor cleaners, aterpineol, geraniol, citronellol, bionone, dihydromyrcenol , 2-butoxyethanol and benzyl alcohol using gas chromatography mass spectrometry (GC/MS). Products from the reaction of these chemicals and NO3. were determined using the chemical derivatization agents O-( 2,3,4,5,6-pentafluorobenzyl) hydroxylamine (PFBHA) and N,Obis( trimethylsilyl) trifluoroacetamide (BSTFA) with GC/MS.
